Abstract:

Delays were measured in a small rocket motor using a single pair of impinging fuel and oxidizer streams at 70 deg, 32 deg, and -40 deg F with fuel containing 0, 10, 20, 30, and 40 vol- heptane. The acid was adjusted to 1 H sub2 O, 0.5 NO sub2, and 98.5 HNO sub3. Hard starts and long, variable delays were obtained in the lowest EtSsub3 P concentration range. The delays were short and independent of concentration or temperature with 90 and 100 EtSsub3 P. The time of ignition was determined by photocell and chamber-pressure pickup methods the values agreed within the precision of measurement. Precaution similar to those for PhNH sub2 or N sub2 H sub 4 are necessary in handling EtS sub3 P.
