Essay / CEV Design - 694
My design is very similar to the Orion, but not quite the same. The shape of the service module is spherical, as it is the most efficient 3D shape, while the control module has a conical shape. This CEV is powered by a single OMS (Orbital Maneuvering System) engine at the end of the service module. . The booster will use a methane/oxygen fuel rather than the hydrazine/nitrogen tetroxide fuel used on Apollo because it has a greater specific impulse, meaning it burns longer for the same amount. Four RCS (reaction control system) thrusters located on the control module above the engine can modify the orientation of the craft in space. They enable the CEV to perform pitch, roll and yaw rotational maneuvers as well as translational maneuvers along the X, Y and Z axes. The guidance, navigation and control system concerns the destination, The current location and trajectory of the CEV. These devices detect vehicle movement and inform the CNG of what is happening. Inertial measurement units (IMU) contain gyroscopes to measure and provide attitude and inertial velocity data to the G...
