3. Dr. Ted Talay<br />

Dr. Talay worked in the Vehicle Analysis Branch at NASA Langley Research<br />

Center. These equations were handed out as class notes <strong>for</strong> ME250, Launch<br />

Vehicle Design, at George Washington University in 1992, which he taught.<br />

Their emphasis is on rocket powered vehicles. Many <strong>of</strong> the equations provided<br />

are based on the Space Shuttle.<br />

4. Marquardt report NAS7-377 [iv]<br />

a. These equations are from a report by The Marquardt Corporation in 1966.<br />

They are published in NAS7-377, a study <strong>of</strong> composite propulsion systems on<br />

launch vehicle mass. The study vehicle is TSTO, and takes <strong>of</strong>f horizontally.<br />

The first stage uses the composite propulsion system on multiple body<br />

configurations. The lifting body version <strong>of</strong> the first stage can be seen in Figure<br />

2 with the second stage attached. Conical and cylindrical body versions were<br />

also modeled with these equations.<br />
