Available in PDF, EPUB and Kindle. Book excerpt: As the orbital debris environment deteriorates, the threat to spacecraft is becoming increasingly significant. Additionally, current protection techniques leave them vulnerable to objects between 1 and 10 cm. The objective for this project was to design a "defender" space vehicle capable of shielding spacecraft from objects in this range of sizes. The design was divided into three stages: first, using SPH simulations, a shield capable of defeating large projectiles was designed based on existing shield types; next, a deployment mechanism that allowed the shield to be stored compactly for launch was designed and analyzed using a vector-based kinematics and dynamics method; finally, a general design of the service module was made. The final design consisted of an eight-layer shield with an umbrella-inspired deployment mechanism. It was 3 m in diameter by 7 m long with the shield folded and had a mass of 5100 kg; proving the feasibility of this measure.

This book was released on 2018-11-07 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current Lower Earth Orbit (LEO) environment has become overly crowded with space debris. An evaluation of types of debris is presented in order to determine which debris poses the greatest threat to operation in space, and would therefore provide a feasible target for removal. A target meeting these functional requirements was found in the Cosmos C-1B Rocket Body. These launchers are spent space transporters which constitute a very grave risk of collision and fragmentation in LEO. The motion and physical characteristics of these rocket bodies have determined the most feasible method of removal. The proposed Orbital Debris Collector (ODC) device is designed to attach to the Orbital Maneuvering Vehicle (OMV), which provides all propulsion, tracking, and power systems. The OMV/ODC combination, the Rocket Body Retrieval Vehicle (RBRV), will match orbits with the rocket body, use a spin table to match the rotational motion of the debris, capture it, despin it, and remove it from orbit by allowing it to fall into the Earth's atmosphere. A disposal analysis is presented to show how the debris will be deorbited into the Earth's atmosphere. The conceptual means of operation of a sample mission is described.

Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of space flight, the collision hazard in Earth orbit has increased as the number of artificial objects orbiting the Earth has grown. Spacecraft performing communications, navigation, scientific, and other missions now share Earth orbit with spent rocket bodies, nonfunctional spacecraft, fragments from spacecraft breakups, and other debris created as a byproduct of space operations. Orbital Debris examines the methods we can use to characterize orbital debris, estimates the magnitude of the debris population, and assesses the hazard that this population poses to spacecraft. Potential methods to protect spacecraft are explored. The report also takes a close look at the projected future growth in the debris population and evaluates approaches to reducing that growth. Orbital Debris offers clear recommendations for targeted research on the debris population, for methods to improve the protection of spacecraft, on methods to reduce the creation of debris in the future, and much more.

Available in PDF, EPUB and Kindle. Book excerpt: The safety of any space system requires a deliberate and interdisciplinary integration of the flight hardware design with the design of its operations throughout the entire lifecycle of the system. This chapter introduces the subsequent chapters that more thoroughly address safety issues associated with the operations of space vehicles, from the design of the infrastructure on ground, through launch, on-orbit, and re-entry operations. This chapter begins with a discussion of safety and risk management at the conceptual level, including several fundamental goals and definitions. The balance of the chapter describes several seminal events and lays the foundation for a graduate level education in space operations safety.

Available in PDF, EPUB and Kindle. Book excerpt: This chapter deals with some key topics of orbital safety. It starts with an overview of the issue of space traffic control and space situational awareness, and then proceeds to address conjunction analyses and collision avoidance maneuvers (CAM), including for the International Space Station. Another kind of collision risk discussed is the jettison of discarded hardware. The chapter then covers rendezvous and docking/berthing operations. Collision safety risks, their causes and consequences, and the measures for protection are discussed in detail. The chapter also covers the issues of space vehicles charging and contamination hazards, including the shock hazard for astronauts involved in extravehicular activities. Finally, the chapter presents end-of life mitigation measures and techniques for space debris removal, such as space tugs, drag devices and electrodynamic propulsion.

Available in PDF, EPUB and Kindle. Book excerpt: Includes the proceedings from the 7th IAASS Conference, "Space Safety is No Accident," held in Friedrichshafen, Germany, in October 2014. The 7th IAASS Conference, “Space Safety is No Accident” is an invitation to reflect and exchange information on a number of topics in space safety and sustainability of national and international interest. The conference is also a forum to promote mutual understanding, trust and the widest possible international cooperation in such matters. The once exclusive “club” of nations with autonomous sub-orbital and orbital space access capabilities is becoming crowded with fresh and ambitious new entrants. New commercial spaceports are starting operations and others are being built. In the manned spaceflight arena a commercial market is becoming a tangible reality with suborbital spaceflights and government use of commercial services for cargo and crew transportation to orbit. Besides the national ambitions in space, the international cooperation both civil and commercial is also gaining momentum. In the meantime robotic space exploration will accelerate and with it the need to internationally better regulate the usage of nuclear power sources. Space-bound systems and aviation traffic will share more and more a crowded airspace, while aviation will increasingly rely on space-based safety-critical services. Finally, most nations own nowadays space assets, mainly satellites of various kinds and purposes, which are under the constant threat of collision with other spacecraft and with the ever increasing number of space debris. Awareness is increasing internationally (as solemnly declared since decades in space treaties) that space is a mankind asset and that we all have the duty of caring for it. Without proactive and courageous international initiatives to organize space, we risk to negate access and use of space to future generations.

Download or read book Space Launch Vehicle Design written by David Woodward and published by . This book was released on 2017 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering design can be broken down into three phases: conceptual design, preliminary design, and detailed design. During the conceptual design phase, several potential configurations are studied towards the identification of the baseline vehicle. Although the least amount of detail is known about the design during the early conceptual design phase, the decisions made during this phase lock in major features effecting life-cycle cost and overall product success. As the next big space race begins, it is critically important to have a readily available tool for launch vehicle designers that is intuitive to use, easy to modify, cost effective, and provides correct results. This thesis details the creation of such a tool for use during the early conceptual design phase by analyzing existing launch vehicle design software and literature in order to adopt a best-practice approach to launch vehicle sizing. In addition to correctly sizing the vehicle calculating the initial parameters, the tool also determines the vehicle's basic geometric information and runs an ascent-to-orbit trajectory simulation to verify the design's validity. The tool is capable of sizing fully expendable space launch vehicles, fully expendable vehicles whose final stage is to be used for both ascent-to-orbit and additional orbital maneuvering after reaching the parking orbit, and vehicles whose first stage performs a self-recovery through the boostback and vertical landing method.

Download or read book Conceptual Design of Two Stage To Orbit Hybrid Launch Vehicle written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-24 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of this design class was to design an earth-to orbit vehicle to replace the present NASA space shuttle. The major motivations for designing a new vehicle were to reduce the cost of putting payloads into orbit and to design a vehicle that could better service the space station with a faster turn-around time. Another factor considered in the design was that near-term technology was to be used. Materials, engines and other important technologies were to be realized in the next 10 to 15 years. The first concept put forth by NASA to meet these objectives was the National Aerospace Plane (NASP). The NASP is a single-stage earth-to-orbit air-breathing vehicle. This concept ran into problems with the air-breathing engine providing enough thrust in the upper atmosphere, among other things. The solution of this design class is a two-stage-to-orbit vehicle. The first stage is air-breathing and the second stage is rocket-powered, similar to the space shuttle. The second stage is mounted on the top of the first stage in a piggy-back style. The vehicle takes off horizontally using only air-breathing engines, flies to Mach six at 100,000 feet, and launches the second stage towards its orbital path. The first stage, or booster, will weigh approximately 800,000 pounds and the second stage, or orbiter will weigh approximately 300,000 pounds. The major advantage of this design is the full recoverability of the first stage compared with the present solid rocket booster that are only partially recoverable and used only a few times. This reduces the cost as well as providing a more reliable and more readily available design for servicing the space station. The booster can fly an orbiter up, turn around, land, refuel, and be ready to launch another orbiter in a matter of hours. Unspecified Center NASA-CR-190006, NAS 1.26:190006 NASW-4435...

Available in PDF, EPUB and Kindle. Book excerpt: The lack of widespread education in space safety engineering and management has profound effects on project team effectiveness in integrating safety during design. On one side, it slows down the professional development of junior safety engineers, while on the other side it creates a sectarian attitude that isolates safety engineers from the rest of the project team. To speed up professional development, bridge the gap within the team, and prevent hampered communication and missed feedback, the entire project team needs to acquire and develop a shared culture of space safety principles and techniques.The second edition of Safety Design for Space Systems continues to address these issues with substantial updates to chapters such as battery safety, life support systems, robotic systems safety, and fire safety. This book also features new chapters on crew survivability design and nuclear space systems safety. Finally, the discussion of human rating concepts, safety-by-design principles, and safety management practices have also been revised and improved. With contributions from leading experts worldwide, this second edition represents an essential educational resource and reference tool for engineers and managers working on space projects.

Download or read book Conceptual Design of a Lunar Shuttle Transport Vehicle written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1961 the former Soviet Union successfully launched the first human into space marking the beginning of the 'Space Race' with the United States. Forty years later, the United States and Russia are working together in support of the International Space Station (ISS). The US Space Shuttle fleet and Russian Soyuz capsule and rockets are being used to replenish the ISS. In light of the latest shuttle accident and aging systems, NASA has been pursing alternatives to replace the shuttle fleet. This study is a conceptual design of a spacecraft designed to meet the following requirements: 1. Transport a crew of eight from Kennedy Space Center in Florida to and from the International Space Station recovering at the Edwards Air Force Base complex in southern California, 2. Transport a crew of eight from the Kennedy Space Center to a future lunar base, and 3. Refuel at the future lunar base using propellant sources mined from moon, launch and return to earth. The spacecraft system, Lunar Shuttle Transport (LST), was designed by tailoring the aircraft design methods presented in Raymer's, 'Aircraft Design: A Conceptual Approach' (1999) to spacecraft design. A design method outline was developed to establish a roadmap for the vehicle design. This study found that the desired configuration for the vehicle would be very similar in shape to the proposed lifting body designs of NASA's Assured Crew Return Vehicle and Orbital Space Plane. Unlike NASA's cancelled X-33 demonstration program, the 1st system would not be a single stage to orbit design but rather would launch using a rocket system with multiple stages. The Lunar Shuttle Transport (LST) would use aerodynamic braking to decelerate during reentry into earth's atmosphere and would rely on a parachute system and rocket engines for the final landing on skids. For the lunar mission, the 1st would use an additional stage for the translunar orbit insertion. The 1st would rely on its main engines both for insertion into the low lunar orbit and the eventual landing on the moon. The launch from the moon would require that the 1st be refueled by a source on the moon. The lunar launch and return trip to earth would be accomplished using the 1st main engines.

This book was released on 1989 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The orbital debris environment model contained in this report is intended to be used by the spacecraft community for the design and operation of spacecraft in low Earth orbit. This environment, when combined with material dependent impact tests and spacecraft failure analysis, is intended to be used to evaluate spacecraft vulnerability, reliability, and shielding requirements. The environment represents a compromise between existing data to measure the environment, modeling of these data to predict the future environment, the uncertainty in both measurements and modeling, and the need to describe the environment so that various options concerning spacecraft design and operations can be easily evaluated.

Download or read book Design and Analysis of Orbital Debris Protection for Spacecraft Composite Pressure Vessels written by Aleksandr Cherniaev and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Being parts of spacecraft systems, composite overwrapped pressure vessels (COPVs) are exposed to orbital debris environment. In the case of impact of orbital debris on a composite vessel, the vessel may fail non-catastrophically, possibly resulting in the loss of spacecraft, or catastrophically, producing numerous non-trackable fragments, which may result in the loss of spacecraft and also affect and destroy other active and future spacecraft in neighbor orbits. Consequences of orbital debris impacts, therefore, must be minimized with the use of an appropriate design strategy. For a weight-efficient design providing high level of protection for spacecraft composite pressure vessels, the following design strategy is suggested in this study: • Exclude any involvement of the pressure wall in resisting orbital debris impacts by means of an external shielding designed for the same tolerable risk of penetration as the shielding of any other critical subsystem of the spacecraft (R1tol; typically, 1-5%); • Ensure that the shielded COPV will not fail catastrophically under conditions corresponding to even stricter tolerable risk of penetration (R2tol), such that R2tol

Download or read book Limiting Future Collision Risk to Spacecraft written by National Research Council and published by National Academies Press. This book was released on 2011-12-16 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Derelict satellites, equipment and other debris orbiting Earth (aka space junk) have been accumulating for many decades and could damage or even possibly destroy satellites and human spacecraft if they collide. During the past 50 years, various National Aeronautics and Space Administration (NASA) communities have contributed significantly to maturing meteoroid and orbital debris (MMOD) programs to their current state. Satellites have been redesigned to protect critical components from MMOD damage by moving critical components from exterior surfaces to deep inside a satellite's structure. Orbits are monitored and altered to minimize the risk of collision with tracked orbital debris. MMOD shielding added to the International Space Station (ISS) protects critical components and astronauts from potentially catastrophic damage that might result from smaller, untracked debris and meteoroid impacts. Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Program examines NASA's efforts to understand the meteoroid and orbital debris environment, identifies what NASA is and is not doing to mitigate the risks posed by this threat, and makes recommendations as to how they can improve their programs. While the report identified many positive aspects of NASA's MMOD programs and efforts including responsible use of resources, it recommends that the agency develop a formal strategic plan that provides the basis for prioritizing the allocation of funds and effort over various MMOD program needs. Other necessary steps include improvements in long-term modeling, better measurements, more regular updates of the debris environmental models, and other actions to better characterize the long-term evolution of the debris environment.
