Abstract: A positive displacement, constant pressure Brayton cycle engine (40) including a compressor (42), a combustion chamber (46), a motor (44) and means for operating the engine in a substantially constant pressure Brayton cycle including means for continuously heating the gas in the combustion chamber (46) at constant pressure and means for feeding a continuous stream of hot, compressed gas at constant pressure solely to the motor (44). Preferably one or both of the compressor (42) and motor (44) are positive displacement rotary sliding vane devices. The engine (40) can be operated with an intermittent hot-cool operating cycle and with various throttle control systems.

Abstract: A constant pressure Brayton cycle engine (40) including a combustion chamber (46) and a positive displacement compressor (42) connected by a shaft (41) to an output wheel (44). Gas is fed to the compressor (42), then to the combustion chamber (46) and then to the output wheel (44). The engine (40) can be either open cycle or closed cycle. The compressor (42) can be of any suitable type such as a sliding vane, a Roots type blower (sometimes called a screw or gear compressor), a regenerative blower, or a liquid seal (Nash) blower. The output wheel (44) can be any of these types or also a dynamic (axial or centrifugal) turbine wheel.

Abstract: A vehicle (10) with a rotary sliding vane engine (14) including a compressor (18), a combustion chamber (20), and a motor (22) in which the braking is done by connecting the rotor of the compressor (18) to a wheel (12) and braking rotation of the rotor by controlling the gas flow through the rotary sliding vane compressor (18), 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 (28) for later use in operating the vehicle engine (14), thus recovering a portion of the kinetic energy of the vehicle (10). The rotary slide vane motor (22) can also be used as the brake by controlling the inlet thereto. The compressor (18) and motor (22) can be separate units or portions of one unitary rotary sliding vane device. The compressor brake and motor-brake can be used together or separately and as integral or separate parts of a rotary sliding vane engine (14) and also with other different types of engines.
