A mounting system for two turboshaft gas turbine engines which are connected by a coupling gearbox. The mounting system comprises a front mounting attached to the gearbox which permits pivotal movement of the engine/gearbox assembly but restrains longitudinal movement and two strut members which support the engines vertically but provide no lateral or longitudinal support. The engines are interconnected by link members and an intermediate member rotatably attached to the vehicle which permit relative lateral movement between the engines but constrain any lateral movements of the engines which are in unison relative to the vehicle.

Mounting system for coupled turboshaft gas turbine engines

An oil tank suitable for an aircraft mounted gas turbine engine is divided into three series connected chambers. Aerated oil after engine use is fed into the first chamber and de-aerated oil withdrawn from the third chamber for engine use. The chambers are interconnected in such a manner that when the tank is inverted, a reservoir of oil is retained within the third chamber to provide a continued supply of oil to the oil outlet for a finite time period and insufficient oil flows into the first chamber from the second to obstruct an air vent provided in the first chamber.
