Available in PDF, EPUB and Kindle. Book excerpt: The space simulation chambers are systems used to recreate as closely as possible the thermal environmental conditions that spacecraft experience in space, as well as also serve to space components qualification and material research used in spacecraft. These systems analyze spacecraft behavior, evaluating its thermal balance, and functionalities to ensure mission success and survivability. The objective of this chapter is to give a broad overview on space simulation chambers, describe which are the environmental parameters of space that can be simulated in this type of ground test facilities, types of the space environment simulators, class of phenomena generated inside, and the technological evolution of these systems from its conception. This chapter describes the basic systems and devices that compose the space simulation chambers.

This book was released on 2012 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 2001 the Space Science and Engineering Lab (SSEL) at Montana State University has designed and built a variety of space hardware, as well as developed the facilities necessary for environmental testing of flight hardware. In late 2005, the SSEL began developing a system to simulate the vacuum environment of near-space which would allow for rudimentary outgassing testing as well as thermal testing of electronics and spacecraft components. To truly test hardware and validate hardware analysis and design, the ability to cycle between the expected temperature extremes in a vacuum environment was essential. The usage and operation of thermal vacuum systems was investigated, requirements for a thermal vacuum system were defined, and possible design options were considered. A Finite Element Analysis (FEA) was performed to predict the heat load in Watts on the system when a 40 kg nanosatellite (50 cm x 50 cm x 60 cm) was cycled between -40°C and +80°C at rates of temperature change from 1°C/min to 5°C/min. Additional research, analysis, and design was performed on a thermal shroud surrounding the same nanosatellite and operating under identical conditions. Radiation heat transfer between the satellite on the shroud's inside and the vacuum chamber on the shroud's outside was calculated using the radiation network approach. The LU decomposition method was used to solve the resulting set of simultaneous equations. From the results, a design was selected for the system base plate on which the nanosatellite rested, with the capability of sinking or sourcing 833 W of heat power. Similarly, the thermal shroud was designed to sink or source up to 704 W through the shroud body, and up to 229 W through the shroud top. Testing was performed to validate both the FEA model and the physical hardware. Temperature measurements were taken during system testing to validate the design, and as a means to compare the FEA model of the base plate and the radiation heat transfer calculations with the performance of the system hardware. The results indicated that the system functioned as designed, that it met the design requirements, and that it was capable of completely and safely testing satellites and other space hardware.

This book was released on 2018-06-11 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few undertakings in the history of humanity can compare to the great technological achievement known as Project Apollo. Among those who witnessed Armstrong#s flickering television image were thousands of people who had directly contributed to this historic moment. Amongst those in this vast anonymous cadre were the personnel of the Space Environment Simulation Laboratory (SESL) at the Manned Spacecraft Center (MSC) in Houston, Texas. SESL houses two large thermal-vacuum chambers with solar simulation capabilities. At a time when NASA engineers had a limited understanding of the effects of extremes of space on hardware and crews, SESL was designed to literally create the conditions of space on Earth. With interior dimensions of 90 feet in height and a 55-foot diameter, Chamber A dwarfed the Apollo command/service module (CSM) it was constructed to test. The chamber#s vacuum pumping capacity of 1 x 10(exp -6) torr can simulate an altitude greater than 130 miles above the Earth. A "lunar plane" capable of rotating a 150,000-pound test vehicle 180 deg replicates the revolution of a craft in space. To reproduce the temperature extremes of space, interior chamber walls cool to -280F as two banks of carbon arc modules simulate the unfiltered solar light/heat of the Sun. With capabilities similar to that of Chamber A, early Chamber B tests included the Gemini modular maneuvering unit, Apollo EVA mobility unit and the lunar module. Since Gemini astronaut Charles Bassett first ventured into the chamber in 1966, Chamber B has assisted astronauts in testing hardware and preparing them for work in the harsh extremes of space.Walters, Lori C.Johnson Space CenterCARBON ARCS; COMMAND SERVICE MODULES; EXTRAVEHICULAR ACTIVITY; FLICKER; LUNAR MODULE; ROTATION; SOLAR SIMULATION; SPACE ENVIRONMENT SIMULATION; VACUUM CHAMBERS; ASTRONAUTS; ENGINEERS; HOUSTON (TX); MANEUVERS; MANNED SPACECRAFT; MOBILITY; PERSONNEL; TELEVISION SYSTEMS

Available in PDF, EPUB and Kindle. Book excerpt: Simulation techniques provide a practical and relatively inexpensive means of obtaining thermal-vacuum characteristics of spacecraft and components. The results of these tests can be evaluated and compared with telemetered measurements of equipment when under actual orbital flight conditions. The ANNA earth satellite (1962 Beta MU 1) cited in this report is a typical example of a spacecraft being subjected to a thorough environmental test program prior to a successful orbital flight.
