Astrobee is the designation of series of American sounding rockets with 1 - 3 stages. Aerojet-designed family of sounding rockets conceived as a lower-cost replacement of the liquid-propellant Aerobee. Several versions were realized. The three-stage Astrobee 500 (first stage: Genius, second stage: Alcor, third stage: Asp) has a ceiling of 1000 km, a takeoff thrust of 161 kN, a takeoff weight of 900 kg, a diameter of 0.38 m and a length of 7.80 m. The three-stage Astrobee 1500 (first stage: Recruit, second stage: Aero jet, third stage: Alcor) has a ceiling of 1000 km, a takeoff thrust of 566 kN, a takeoff weight of 5200 kg, a diameter of 0.79 m and a length of 10.40 m. The two-stage Astrobee 200 (first stage: Genius, second stage: Alcor) has a ceiling of 350 km, a takeoff thrust of 161 kN, a takeoff weight of 800 kg, a diameter of 0.38 m and a length of 6.30 m. The single-stage Astrobee D has a ceiling of 140 km, a takeoff thrust of 23.00 kN, a takeoff weight of 100 kg, a diameter of 0.15 m and a length of 3.90 m. The single-stage Astrobee F has a ceiling of 375 km, a takeoff thrust of 178.00 kN, a takeoff weight of 1500 kg, a diameter of 0.38 m and a length of 11.50 m. ==External links== *http://www.astronautix.com/lvs/astee500.htm *http://www.astronautix.com/lvs/aste1500.htm *http://www.astronautix.com/lvs/astee200.htm *http://www.astronautix.com/lvs/astobeed.htm *http://www.astronautix.com/lvs/astobeef.htm 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Astrobee」の詳細全文を読む スポンサード リンク
