• Fuel Pump Design

Delphi participated in the development of the fuel pumps of the F-22 Raptor. This involved brushless DC motor and induction motor control electronics design and flight qualification.

• Rudder Control Software
• Throttle Module Conversion Electronics

Delphi developed two subsystems for this passenger jet: the rudder control software and the throttle module conversion electronics. Both systems were developed under FAA DO-178 Level A processes. This extensive process is applied for systems such as this where the equipment is life-critical. Out of 110 software systems on this aircraft, Delphi was the first developer to pass the FAA audit process and was used by the FAA as a "guinea pig" to prove their new process before applying it to the other developers.

• Booster Stage Thrust Vector Controller

Delphi performed system design, software, and system integration tasks for the Thrust Vector Controller. For about the first 15 seconds of the launch the Tactical Tomahawk missile is powered by a rocket motor. The function of the Thrust Vector Controller is to control the tabs which block portions of the rocket nozzle, controlling the shape of the plume and the path of the missile. At the end of the initial 15 second launch sequence the rocket motor with the TVC hardware and electronics is jettisoned.

The TVC receives commands from the TT Mission Control Unit over an RS-422 bus and uses these commands to control 2 motors. Each motor controls 2 thrust vectoring tabs simultaneously. The two tabs associated with each motor move in parallel with one tab moving into the rocket plume while the second moves out of the plume. One motor controls two tabs for the thrust-vectoring pitch and the other motor controls two tabs for the thrust-vectoring yaw.
