  • Patent number: 9096315
    Abstract: An apparatus for recovering kinetic energy released during and aircraft landing after ground contact, for ground and/or flight operation, comprising at least one energy converter for conversion of the kinetic energy into another energy form, where the energy converter is located in the area of the nose landing gear and/or in the area of the main landing gear of the aircraft. At least one energy storage system is provided for receiving and releasing at least a part of the converted kinetic energy. The apparatus has a high degree of multiple utilization and enables, for example, maneuvering of a landed aircraft on the taxiway independently of the engines, where the aircraft is substantially moved with the braking energy recovered during the landing process. Since the main engines are no longer required for maneuvering, there is a considerable potential for saving energy and the use of motor-operated tow vehicles is eliminated.

  • Patent number: 4798053
    Abstract: A vehicle kinetic energy reclaiming system employs the vehicle's engine (10) to compress air when the vehicle decelerates and reuses the stored compressed air to drive an air motor (78) which assists in powering the vehicle when it is underway again. When the vehicle begins to decelerate, an accelerator switch (24) causes a valve (38) in a carburetor (34) bypass pipe to open, allowing ample air to enter and be compressed by the engine, which is driven by the vehicle's kinetic energy through the transmission (42). This helps decelerate the vehicle and saves its brakes. The same switch closes a valve (22) in the exhaust line (18-19), causing the compressed air to be diverted to a storage tank (26). When enough pressure in accumulated in the tank, a pressure release valve (74) in the tanks' output opens and a valve switch (72) closes, allowing air to reach an accelerator-controlled valve (88). This enables a clutch (76), which connects the air motor to the vehicle's transmission, to be operated.

  • Patent number: 4637213
    Abstract: Arrangement for a thermal, steam-powered engine in a submarine vehicle, for example a torpedo. A condenser is so arranged as to separate the exhaust from the engine into a condensable exhaust fraction and into a non-condensable exhaust fraction. A compressor, which is connected to the engine for the purpose of silencing, is so arranged as to compress only the non-condensable exhaust fraction which, after compression, is discharged through an exhaust outlet into the surrounding sea water. The condenser is in the form of a sleeve which for silencing purposes encloses both the engine and the compressor. A sound-deadening gap is arranged between the condenser and the hull of the vehicle.

  • Patent number: 4590767
    Abstract: The invention comprises a vehicle having wheels, a drive shaft, and a gasoline or diesel engine as a primary source of power, and an air operated engine and an electrohydraulic motor coupled to the drive shaft as the secondary and auxiliary power. Coupled to the output shaft of the air engine is a rotary vane which utilizes bypassed exhaust gases from both the gasoline/diesel engine and the air engine as an auxiliary assist to the air engine, and both the rotary vane and the air engine compress air for storage during vehicle deceleration and braking. Kinetic energy for operating the secondary and auxiliary power to the vehicle is recovered by the application of an alternator, hydraulic pump and an air compressor to each moving tire and the drive train shaft of the non stationary vehicle during acceleration, deceleration and braking. The recovered kinetic energy is transmitted either directly to the auxiliary power equipment for immediate application or is stored for later use.

  • Patent number: 4479356
    Abstract: An energy recovery system for a machine, and particularly an automotive vehicle, includes an energy storage device which selectively receives energy from the prime mover for storage via a predetermined path and delivers stored energy to the prime mover load via the same path. In the preferred embodiment the energy storage device is an elastomeric tube which is disposed for rotational movement about a shaft and secured at the ends to respective end members. Braking units permit selective braking and releasing of the end members relative to fixed supports. A set of planet gears are controlled by the brake actuation to drive a sun gear or be driven by a ring gear to effect energy inflow and outflow, respectively, from the elastomeric tube. The storage device is permitted to store energy or release its stored energy as a function of vehicle control and operational parameters.

  • Patent number: 4290268
    Abstract: An auxiliary kinetic energy recovery system is provided for a vehicle with a rotary sliding vane engine including a compressor, a combustion chamber and a motor in which the braking is done by connecting the rotor of the compressor to a wheel and braking rotation of the rotor by controlling the gas flow through the rotary sliding vane compressor, such as by varying the outlet to increase the pressure ratio. This eliminates the conventional friction brakes. The compressed air generated during braking is fed to a surge tank for later use in operating the vehicle engine, thus recovering a portion of the kinetic energy of the vehicle. Additional amounts of kinetic energy are recovered by means of a closed circuit compressible gas circulating system which comprises an auxiliary compressor actuated by the same shaft as that attached to the engine compressor.

  • Patent number: 4163367
    Abstract: The adaptation of a compressed-fluid (such as compressed-air) powered turbine in conjunction with the use of a flywheel as a hybrid propulsion system for nonstationary applications, such as vehicle drive, is shown and its practicality demonstrated. This propulsion system requires a nonpolluting fluid, such as air, and a source of mechanical or electrical energy to compress said fluid and energize said flywheel, both of which act as energy storage media. An expander/compressor unit, such as a turbine, is used for converting the stored energy of said compressed-fluid into shaft power by expanding said fluid, and recovering the braking energy during vehicle deceleration by compressing and storing the atmospheric air (if air is used). Said flywheel is used not only for providing peak powers necessary for vehicle acceleration but also for recovering the braking energy during vehicle deceleration and refilling said compressed-fluid in an emergency.
