Embodiment Construction

[0017] In a preferred embodiment of the present invention, figure 1 The rotary reciprocating sliding vane air pump shown, and the two boundary layer gas turbines ( figure 2 one of which is shown) combine to form Figure 3-4 The deflagration-driven gas turbine system shown.

[0018] refer to figure 1 , the rotary reciprocating sliding vane air pump includes a housing 11 having a slotted rotor 12 mounted on a slotted shaft 13 . The housing 11 has a cavity whose center is offset from the centerline of the shaft 13, whereby an eccentric annular space is formed between the rotor 12 and the cavity wall. A single mechanically reciprocating sliding metal vane 14 is positioned in the slotted rotor 12 to extend across the diameter of the cavity 15 of the housing 11 . The blades are dimensioned such that, when the rotor turns, both ends of the blades contact the cavity walls. The cavity walls are generally cylindrical; however, can be made slightly non-cylindrical if desired to mai...

Abstract

A rotary mechanically reciprocated sliding vane air pump is integrated with pulse driven boundary layer gas turbines on a single shaft. The shaft is slotted and is aligned with a slotted rotor that mechanically drives a reciprocating sliding metal vane. The cavity in the housing is offset from the center line of the shaft, creating a cavity between the rotor and the cavity wall. Air is positivelyinduced at the inlet of the cavitated housing and is positively displaced at the outlet. Air inlet and outlet ports enter and exit the cavitated housing wall at 90 degrees and 270 degrees respectively. The compressed air is directed via manifolds into combustion chambers mounted on side walls of the turbine housings. Arcing electrodes detonate the fuel-air mixture producing high temperature and pressure pulsed working fluid that is exhausted via nozzles into the vanes of the boundary layer gas turbines.

Description

technical field [0001] The present invention relates to the technical field in which a rotary mechanical reciprocating sliding metal vane air pump and a boundary layer turbine are combined into a deflagration pulse driven gas turbine system. Background technique [0002] In the field of explosion-pulse driven gas turbines, such as the gas turbine proposed in U.S. Patent 6,000,214, the turbine is a modified Pelton (Pelton) water wheel driven by explosion, which has the effect of kinetic energy impact and expansion gas A vane that passes through the vane race for forced movement. The compressed air is generated using a Roots-type lobe blower or a sliding lobe blower mounted externally on the main turbine and shaft assembly. [0003] A lobe blower has two shafts driving two vanes synchronized by a gearbox and therefore cannot be mechanically coupled to the main shaft of a pulse-driven gas turbine. Sliding vane blowers in commercial use use graphite vanes, usually four vanes p...
