A Rolls Royce AE3007 Engine powers the Global Hawk UAV. In order to start the engine, an Air Turbine Starter is required. Since the UAV does not have an Auxiliary Power Unit on board, this engine could only be started on the ground. This means that in case of a flame out this aircraft could be lost. Therefore, the ability to start the engine in the air would contribute significantly to the UAV survivability. Furthermore, if the starter could also start the engine on the ground, we could eliminate the ATS and save significant weight and cost.
Innovative Power Solutions is proposing to develop a brushless Starter/Generator, capable of starting the AE3007 engine, as well as supplying 500 Amps at 28 VDC. This generator will replace the current 200 Amp, 28 VDC brush type generator, which requires periodic (less than 1000 hours) overhauling. A Starter/GCU will control this generator. During the start mode the start converter will control the start sequence that will be tailored to the engine requirements. The GCU will control the generator during the power generation mode. Other significant improvements are extended life due to matching torque/speed curve to start sequence and reduced maintenance requirements.
