The shuttle RCS jets are most often used for on orbit maneuvering and attitude control. Although most of the control systems that use RCS jets are in spacecraft, several Earth entry vehicles also use RCS jets during the atmospheric portion of the flight. Typically, only the aft RCS jets are used during entry, due to aerodynamic coupling effects.

These pods also contained the Orbiter's aft set of reaction control system (RCS) engines, and so were referred to as OMS/RCS pods. The OM engine and RCS both burned monomethylhydrazine (MMH) as fuel, which was oxidized with MON-3 (mixed oxides of nitrogen, 3% nitric acid), with the propellants being stored in tanks within the OMS/RCS pod ...

The effect of interaction between the reaction control system (RCS) jets and the flow over the space shuttle orbiter in the atmosphere was investigated in the NASA Langley 31-inch continuous flow hypersonic tunnel at a nominal Mach number of 10.3 and in the AEDC continuous flow hypersonic tunnel B at a nominal Mach number of 6, using 0.01 and ...

This report defines the FCS as including the SDAP, the motion sensors (IMU), and the RCS (jet) model. The RCS hardware models are designed for rotation only. The FCS model can be configured as a logical unit in a shuttle/payload simulation as shown in Figure 1. Figure 1: Shuttle/payload simulation.

Each aft RJDhalf-boxcontrols all jets on oneleft aft and one right aft manifold, with two units also controlling one VRCS manifold pair each. There are five identical IBM AP-101 model GPCs, each with 104K of 35-bit full words.

The space shuttle has a forward reaction control system (RCS) located in the nose of the vehicle and an aft RCS located in the right and left pods at the rear of the shuttle. These reaction control engines can be used for 100 missions and can sustain 20,000 starts and 12,800 seconds of cumulative firing.

After main engine cutoff, the RCS thrusters in the forward and aft RCS pods are used to provide attitude hold until external tank separation. At ET separation, the RCS provides a minus...
