Alcor (rocket Engine)
Alcor (also known as Zebra or 30-KS-8000) was a solid rocket engine, originally developed by Aerojet for the United States Air Force, US Air Force as the third stage of the Athena RTV, Athena test vehicle. Its main appeal was a high mass fraction due to the Aerowrap chamber fabrication process. However, production issues with joint sections limited its use. Alcor engines were used from 1960 to 1977. The original version was used on a series of rockets: Blue Scout Jr, Blue Scout Junior, Astrobee, Astrobee 200, Blue Scout Jr SLV-1C, Ram (rocket), RAM B, Blue Scout Jr SLV-1B(m), Athena RTV, Strypi, Strypi VI and Strypi VIIAR. Initially produced with polyurethane propellant, it transitioned to Polybutadiene acrylonitrile, polybutadiene, leading to the Alcor 1A (23KS-11000) variant. This variant featured improved nozzle, chamber insulation, and expansion ratio, increasing the mass fraction from 0.886 to 0.906. Both Alcor 1 and 1A were used in Astrobee, Astrobee 500 and 1500 vehicles. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
