This book was released on 2018-06-11 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aircraft industry jointly with NASA is studying enabling technologies for higher speed, longer range aircraft configurations. Higher speeds, higher temperatures, and aerodynamics are driving these newer aircraft configurations towards long, slender, flexible fuselages. Aircraft response during ground operations, although often overlooked, is a concern due to the increased fuselage flexibility. This paper discusses modeling and simulation of the High Speed Civil Transport aircraft during taxiing, take-off, and landing. Finite element models of the airframe for various configurations are used and combined with nonlinear landing gear models to provide a simulation tool to study responses to different ground input conditions. A commercial computer simulation program is used to numerically integrate the equations of motion and to compute estimates of the responses using an existing runway profile. Results show aircraft responses exceeding safe acceptable human response levels.Reaves, Mercedes C. and Horta, Lucas G.Langley Research CenterAIRCRAFT PERFORMANCE; COMPUTERIZED SIMULATION; FINITE ELEMENT METHOD; LANDING SIMULATION; SUPERSONIC TRANSPORTS; TAKEOFF; TAXIING; AIRFIELD SURFACE MOVEMENTS; DYNAMIC RESPONSE; MATHEMATICAL MODELS; FLIGHT CHARACTERISTICS; TRANSPORT AIRCRAFT; EQUATIONS OF MOTION; AIRCRAFT LANDING; COMMERCIAL AIRCRAFT; LANDING GEAR; NUMERICAL INTEGRATION; VIBRATION MODE

This book was released on 2018-09-23 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mathematical model and associated code to simulate a high speed civil transport aircraft - the Boeing Reference H configuration - are described. The simulation was constructed in support of advanced control law research. In addition to providing time histories of the dynamic response, the code includes the capabilities for calculating trim solutions and for generating linear models. The simulation relies on the nonlinear, six-degree-of-freedom equations which govern the motion of a rigid aircraft in atmospheric flight. The 1962 Standard Atmosphere Tables are used along with a turbulence model to simulate the Earth atmosphere. The aircraft model has three parts - an aerodynamic model, an engine model, and a mass model. These models use the data from the Boeing Reference H cycle 1 simulation data base. Models for the actuator dynamics, landing gear, and flight control system are not included in this aircraft model. Dynamic responses generated by the nonlinear simulation are presented and compared with results generated from alternate simulations at Boeing Commercial Aircraft Company and NASA Langley Research Center. Also, dynamic responses generated using linear models are presented and compared with dynamic responses generated using the nonlinear simulation.Sotack, Robert A. and Chowdhry, Rajiv S. and Buttrill, Carey S.Langley Research CenterSUPERSONIC TRANSPORTS; TRANSPORT AIRCRAFT; BOEING AIRCRAFT; CIVIL AVIATION; AIRCRAFT MODELS; MATHEMATICAL MODELS; COMPUTERIZED SIMULATION; ALGORITHMS; AERODYNAMIC CHARACTERISTICS; DYNAMIC RESPONSE; FLIGHT CONTROL; CONTROL SYSTEMS DESIGN; LANDING GEAR; NONLINEAR EQUATIONS; EQUATIONS OF MOTION; UNSTEADY FLOW; STEADY FLOW...

Available in PDF, EPUB and Kindle. Book excerpt: An assessment of a proposed configuration of a high-speed civil transport was conducted by using NASA and industry research pilots. The assessment was conducted to evaluate operational aspects of the configuration from a pilot's perspective, with the primary goal being to identify potential deficiencies in the configuration. The configuration was evaluated within and at the limits of the design operating envelope to determine the suitability of the configuration to maneuver in a typical mission as well as in emergency Or envelope-limit conditions. The Cooper-Harper rating scale was used to evaluate the flying qualities of the configuration. A summary flying qualities metric was also calculated. The assessment was performed in the Langley six-degree-of-freedom Visual Motion Simulator. The effect of a restricted cockpit field-of-view due to obstruction by the vehicle nose was not included in this study.

Book excerpt: After the completion of the National Research Council (NRC) report, Maintaining U.S. Leadership in Aeronautics: Scenario-Based Strategic Planning for NASA's Aeronautics Enterprise (1997), the National Aeronautics and Space Administration (NASA) Office of Aeronautics and Space Transportation Technology requested that the NRC remain involved in its strategic planning process by conducting a study to identify a short list of revolutionary or breakthrough technologies that could be critical to the 20 to 25 year future of aeronautics and space transportation. These technologies were to address the areas of need and opportunity identified in the above mentioned NRC report, which have been characterized by NASA's 10 goals (see Box ES-1) in "Aeronautics & Space Transportation Technology: Three Pillars for Success" (NASA, 1997). The present study would also examine the 10 goals to determine if they are likely to be achievable, either through evolutionary steps in technology or through the identification and application of breakthrough ideas, concepts, and technologies.

This book was released on 2019-12-11 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2019 in the subject Engineering - Aerospace Technology, grade: 1,5, University of Applied Sciences Wildau, language: English, abstract: This Paper will introduce the most developed concept of vertical take off and landing (VTOL) aircrafts and assess them. It will also analyse the key technology challenges and the legislative situation. The world’s population is growing and people continue to move from rural to urban areas. This is accompanied by an increasing number of cars. As a result of this, traffic jams in densely populated areas and long commutes are becoming omnipresent. Extension possibilities for existing infrastructure, especially within urban areas, are very limited due to space. Consequently, innovative alternatives are required. Flying cars, also known as vertical take off and landing (VTOL) aircraft, still appear to be a future vision which seems to be far away. However, to date, more than 200 of such concepts around the world are being developed, some of which are even performing flight tests. The objective of this Master’s Thesis therefore is to evaluate if flying cars have a realistic potential to improve the overloaded ground infrastructure systems on a mid-term ten years basis. In order to answer the research question, a conceptual examination and subsequent classification of the existing concepts is conducted. Based on this a profound content analysis of the four most mature aircraft is carried out. As a result, three significant technical challenges emerge: batteries, noise pollution and the autonomous flying capability. By performing another content analysis on these obstacles, their respective relevance and impact following an upcoming vehicle certification is investigated. Furthermore, VTOL aircraft operations would require legislative amendments. Hence, the current legal situations and actual activities in those regions are studied, where the four companies with the most mature concepts are based. On that basis it can be concluded, that flying cars have a huge potential to relieve the overstressed infrastructure systems on the ground. Although more than ten years will be required to significantly improve this situation, the first flying cars will most likely be visible much sooner. Technical as well as legal challenges exist, but are not insurmountable and especially the latter are relatively well developed already to enable VTOL operations in an urban environment in the near future.

Book excerpt: A simulation study to determine the effect on air traffic control when both Vertical and Short Takeoff and Landing aircraft are introduced into a terminal air traffic control environment was conducted. The simulation was conducted using the Model B Dynamic Air Traffic Control Simulator. Several approach conditions, various glide slope angles, and separation criteria were investigated to determine the effect on a terminal environment. It was concluded that Vertical and Short Takeoff and Landing aircraft could be accommodated in the terminal area using present operational procedures as contained in the Terminal Air Traffic Control Manual 7110.8. However, when Vertical and Short Takeoff and Landing aircraft reduced from terminal area speed to a slow final approach speed, difficulties were encountered in providing not only the desired spacing between these aircraft but between these aircraft and conventional aircraft in the sequence to and on the final approach course. These problems did not exist when Vertical and Short Takeoff and Landing aircraft used a final approach speed compatible with that of conventional aircraft. (Author).
