Soft Limit violations are called out, but their violation has no consequences for aerodynamics or component failures. Dependent on the trajectory of the orbiter, there may or may not be sufficient time to redeem the situation. Where applicable, warnings when the state of the orbiter is getting dangerously close to a limit are called out in addition to a recommendation how to deal with the situation. The general philosophy on limit modeling is that they can be treated dependent on a user setting as 'soft', 'hard' and 'realistic'. The project contains code to simulate the various structural and aerodynamical limits as well as component failures based on sections 4 and 6 of the Space Shuttle crew manual. In the following, descriptions refer to the development version - the last stable or the release version may not have all features described. ascent, orbital insertion, de-orbit, entry, terminal area energy management and landing can be flown largely 'by the book', i.e. The authoritative source for procedures for trajectory management, instrumentation, limits and emergency procedures is the Space Shuttle Crew Operations Manual and currently a normal mission, i.e. The NASA technical reports server supplies a large base of wind tunnel and in-situ performance data of both the mated launch vehicle and the orbiter, and the aerodynamics of the simulated shuttle is based on these documents. In addition to the real avionics and control modes, the idea is also to provide various 'educational' modes and instruments in order to explore and appreciate certain aspects of a Shuttle mission more. While most of the time the real Shuttle is under the control of automatic guidance systems, there are fallback modes to control the spacecraft manually, the so-called CSS (control stick steering) modes, and it is these modes we primarily try to implement. The aim of the Shuttle Project is to create a highly realistic simulation of the capabilities of the Space Shuttle in FlightGear. 12.1 General Space knowledge and tutorials.12 Educational Links / Shuttle technical files.8.3 Nominal Operations Advanced Tutorial.5.2 Auxiliary Power Unit and Hydraulics System.4.7 Entry and touchdown structural and aerodynamical limits.4.4 A note on thruster efficiency in the atmosphere.4 Aerodynamics of the Space Shuttle Orbiter.3.4.3 Key mapping for RCS translation DAP.3.1 The Orbital Maneuvering System engines.2.6 Ascent structural and aerodynamical limits. ![]() 2.3 A note on aerodynamics of the mated vehicle.Sign up for Astronomy Now's NewsAlert service and have the latest news in astronomy and space e-mailed directly to your desktop (free of charge). Step aboard the space shuttle Columbia for a virtual reality tour of the spaceship midway through its maintenance and modification period. The new mirror-like thermal tape saves 37 pounds. Each wing had 15 of the 40-pound doors the aluminum doors weigh only 16 pounds each.Įven the aluminized tape covering the inside of the shuttle's wheel wells is being replaced. Replacing so-called flipper doors on the shuttle's wings with new aluminum ones will also make additional weight savings. ![]() About 1,000 pounds shall be removed, equaling the additional amount of cargo Columbia will be able to launch. The equipment, however, hasn't been used since and now NASA wants it taken out while the Boeing technicians have the shuttle ripped apart. The sensors were flown to gather information about how the shuttle performed during the daring missions, ultimately allowing NASA to declare the space shuttle operational. ![]() In comparison, Columbia is 8,000 pounds heavier than Endeavour, the newest shuttle built in the early 90s.īut efforts are underway to lose some excess pounds on Columbia like removing gauges and data-collecting equipment used on the shuttle's first four test flights in 19. Photos: Spaceflight NowĬolumbia was the first shuttle built to fly into space and it was the heaviest. Below workers remove the heavier tape in the wheel wells. The older flipper doors are removed from Columbia's wings as seen in top photo. ![]() Spaceflight Now | Orbiter Overhaul | The Columbia weight loss plan
