Alternative Space Vehicle Launch Systems
Over the last century chemical propellants have been the dominant fuel source for the aviation and aerospace industry, primarily because they are able to provide ample power for a limited cost. However, over the last decade as the price of chemical propellant continues to soar and their detrimental effect on our environment comes to light, there has been a surge to develop an alternative propul...
متن کاملAdaptive Guidance Systems for Hypersonic Reusable Launch Vehicles
1 0-7803-6599-2/01/$10.00 © 2001 IEEE. Abstract— This paper presents an adaptive guidance system approach applied to hypersonic Reusable Launch Vehicles (RLVs). After an effector failure, it is assumed that the inner-closed-loop system utilizes a reconfigurable control algorithm to recover nominal maneuvering capabilities to the extent possible. However, nominal performance will typically not b...
متن کاملD4ops: Design for Operations of Future Reusable Launch Systems
Designers of space launch systems should be cognizant of the impact of their design assumptions on operational characteristics. Operational metrics such as turnaround time, recurring cost, and headcount are critical factors for the future viability of such systems. The results presented here are from a study that seeks to determine in what manner design approaches can improve the operability of...
متن کاملGeneric Simulation Models of Reusable Launch Vehicles
Analyzing systems by means of simulation is necessarily a time consuming process. This becomes even more pronounced when models of multiple systems must be compared. In general, and even more so in today’s fast-paced environment, competitive pressure does not allow for waiting on the results of a lengthy analysis. That competitive pressure also makes it more imperative that the processing perfo...
متن کاملThe Road from the NASA Access-to-Space Study to a Reusable Launch Vehicle
portunity to reduce launch costs, and improve safety and reliability was to develop a fully reusable single-stage-to-orbit vehicle capable of delivering 25,000 lb to the International Space Station. The study identified many technologies that had to be matured before a commitment could be made to build such a vehicle. NASA accepted the recommendation and the need for new technology as the key t...
