The chamber has a sparkplug (3) with a body (2) having a free end in an opening (8) of a chamber wall (5) to compensate relative movements between a case and the wall. A sealing device (1) has an annular spark plug guide (10) mounted at a radial external e...

A power electrical system is disclosed for a microturbine power generator (12, 14). The invention permits the microturbine to be started using an external DC power source (18). The DC voltage is converted to a variable DC voltage by means of a bi-direction...

An augmenter includes at least one igniter (30) which provides a uniform ignition within the augmenter. The igniter is secured to an igniter housing (82) with a self-locking nut (54) and each igniter includes a biasing mechanism (60) which biases the ignit...
