The Bell Aerosystems Company XLR81 (Model 8096) was an American liquid-propellant rocket engine, which was used on the Agena upper stage. It burned UDMH and RFNA fed by a turbopump in a fuel rich gas generator cycle.

2023年1月19日 · But when selected as the engine to power a new Lockheed upper stage designed specifically for the TOP SECRET Air Force WS-117L space-based reconnaissance program, the re-engineered IRFNA/UDMH rocket engine soon known as Agena became the primary workhorse of America’s first decades in space.

Bell Nitric acid/UDMH rocket engine. Out of production. Used in Agena stage on top of Thor, Atlas, and Titan launch vehicles. First flight 1963. AKA: YLR81-BA. Status: Out of production. Number: 175 . Thrust: 71.20 kN (16,006 lbf). Unfuelled mass: 132 kg (291 lb). Specific impulse: 293 s. Burn time: 265 s. Diameter: 1.52 m (4.98 ft).

阿金纳B为阿金纳A的改型，改进了主要电子和制导装置，换用了贝尔（Bell）公司8096型发动机，真空推力提高了1.95 kN，真空比冲增加了98 m/s，并具有了二次启动能力；箭体贮箱加长了，工作时间较阿金纳A增加了1倍。

The Agena D variant was essentially a "standardized" Agena B, which could accept a variety of payloads. Both used the new engine Bell 8096 with a 30 cm extended nozzle and surface structure. Later, the Agena-D was filled with the new fuel combination HDA/UDMH, what has improves the performance of the engine Bell 8096-39.

It was launched atop Atlas, Thor, Thorad and Titan IIIB rockets. It was equipped with a Bell 8096 engine, which could generate 71 kN of thrust with a burn time of 265 seconds. The first Agena-D launch was of KH-4 #7 on June 28, 1963, and a total of 269 Agena-Ds were launched.

Engine: Bell 8096. Status: Out of Production. One of the real workhorses of U. S. space exploration, Agena was an upper stage which was also employed as a spacecraft, the whole vehicle going into orbit. Agena played a key role in manned space flight; it was the target vehicle for rendezvous and docking maneuvers in NASA's Gemini project.

The Agena B used a Bell 8096 engine and propellant tanks, made integral with the vehicle body. It was used for Ranger lunar probes, with the last three successful. The early Agenas were built to satisfy specific mission requirements, and it was not until the D …

2020年7月26日 · 发动机：BELL 8096*2 【5】整流罩数据. 长度：1.96~3.66 m. 最大直径：1.53 m. 结构质量：~90kg （小型整流罩） 大力神3C（TITAN 3C） 大力神3C运载火箭是在大力神3A的基础上发展起来的。它是以大力神3A为芯级，一级加装2枚固体助推器的捆绑式火箭。
