No particular effort had been made to maximize the specific impulse, that not being the reactor's purpose, but Pewee achieved a vacuum specific impulse of 901 seconds (8.84 km/s), well …

Ideal vacuum specific impulse is reported throughout this document. The calculated value assumes an infinite nozzle expansion ratio, without losses, discharging into a perfect vacuum.

Pewee-1 was a nuclear reactor, designed and built as part of the Rover program, specifically to investigate the performance characteristics of a small reactor for nuclear propulsion in space.

The aerial monitoring and sampling missions of the U-3A and WERL aircraft are reported separately, as is the special study on reactor-released particles of high specific radioactivity.

The exhaust of the engine in the final days of the program was calculated to have a specific impulse of near 850 seconds, almost three times the performance of the kerosene engines of …

Feb 24, 2014 · The Phoebus series of research reactors began testing at test cell C, in June 1965 with Phoebus 1A. Phoebus 1A operated for 10.5 minutes at 1100 MW before unexpected loss …
