TL;DR: An aircraft on-board auxiliary power unit including a gas turbine core and ram combustor uninterruptedly producing relatively low and high velocity hot gases to drive a free, power turbine positioned downstream thereof and interconnected with, and driving an auxiliary equipment-operating shaft to thereby provide a turboramjet aircraft with all flight vehicle power requirements throughout its entire operating regime, including ground standby as mentioned in this paper.

TL;DR: In this paper, the brake pedal engages a clutch disposed between the engine powered transmission and a compressor whereby the compressor is actuated and also supplies air under pressure to the accumulator.
Abstract: Air pumps actuated by rotating wheels of a vehicle force air under pressure into an accumulator. An electrically operated valve suitably controlled by manual switches releases air under pressure from the accumulator to rotate an air turbine, thus rotating a generator supplying power to a battery via a voltage regulator. Depression of the brake pedal engages a clutch disposed between the engine powered transmission and a compressor whereby the compressor is actuated and also supplies air under pressure to the accumulator.

TL;DR: In this paper, an accumulation power station consisting of an electric motor, an air compressor driven by the motor, a storage space for the compressed air generated by the compressor, and an air turbine which is driven during peak-load periods by compressed air from the storage space, is provided.
Abstract: In an accumulation power station comprising an electric motor, an air compressor driven by the motor, a storage space for the compressed air generated by the compressor, an air turbine which is driven during peak-load periods by compressed air from the storage space, and an electric generator driven by the air turbine there is provided a regenerative heat exchanger which accumulates the heat produced when air is compressed while the compressed air storage space is being charged, and which gives off the accumulated heat to the compressed air when the compressed air storage space is being discharged.

TL;DR: For many years, ram air turbines have been used as a source of power on aircraft should an emergency arise or as a continuous source of energy and because the turbine is air operated it can produce power for as long as the aircraft is flying as mentioned in this paper.
