Four firings, and one engine start to expiration of the ignition phase timer, of the Rocketdyne J-2 rocket engine were conducted in Test Cell J-4. The firings were accomplished during test period J4-1801-02 at pressure altitudes from 97,000 to 106,000 ft at engine start. The objectives of the test were to evaluate S-IVB/S-V start condition effects on (1) gas generator and augmented spark igniter chamber ignition characteristics and (2) fuel pump stall characteristics during start tank blowdown for J-2 engine J-2052. Engine thermal conditions predicted for the J-2 engine flight configuration first burn, and restarts after one and two orbits, were simulated.
