MOBEV F2B |
Status: Cancelled 1968. Gross mass: 392 kg (864 lb). Unfuelled mass: 206 kg (454 lb). Specific impulse: 290 s.
It used differential throttling of the lift thrusters. Eight thrusters were used to provide engine out capability and provide an initial lunar thrust to weight ratio of 3. Two thrusters were mounted at the corners of the body in a slightly canted position to provide yaw control. An active three-axis attitude control system was provided. Continuous communications with the lunar base or roving vehicle during exploration were provided by an S-band system integrated with the PLSS system. Multiple landing capability was provided by reusable friction devices for landing energy absorption. A strap-down inertial guidance system provided the required guidance accuracy.
