ALTITUDE SIMULATION

LE M altitude System (G . Gaylord )

Further evaluation of T.,.EM engine propellant flow at low theist

has shown that the rates are within the values e_recified to

Thiokol for design of the altitude system . This refutes the

Thiokol argument that non-performance of the system at minimum

thrust is due to excess engine flow . V

Efforts to secure the consultant services of Dr. Addy of theUniversity of Illinois have failed .

A .S .I . Altitude System (H . Zweig)

A three-stage hold ejector system is being fabricated for CTL-3cell 36 . This system i s designed to evacuate the A. S .I . testcell in 30 seconds after A.S.I .. cutoff. These ejectors will complete

all operational requirements for the altitude system .

J.-2 Altitude System • VTS+3A (0. Haroldsen )

FL1I ..5•.¢049, "Temperature History, VTS-~3A Diffuser Nugrer 3 ;

Addendum I," predicts that the mean diffuser wall temperatureafter 4.5 .seconds of J-2 engine operation will be 2500E without

film coolant. At 4.5 seconds, the film-coolant shroud temperaturewill reach 10000F . Since a 250OF maximum mean wall temperature

has been established, film coolant must be. present at 1, 5seconds after MLV opening.
