Title: The Innovations of Alain Varizat
Introduction
Alain Varizat is a notable inventor based in Bois-le-Roi, France. He has made significant contributions to the field of fuel supply systems for gas turbine engines. With a total of 3 patents to his name, Varizat's work has had a considerable impact on aviation technology.
Latest Patents
One of his latest patents is a device for supplying fuel to a gas turbine engine with a regulated fuel flow rate. This innovative fuel supply device includes a fuel supply pipe that receives fuel at a non-regulated pressure delivered by a pump. It features a device for measuring the flow rate of fuel in the pipe, a first controlled variable-restriction valve mounted in the supply pipe, and a control system connected to the flow rate measurement device and the first valve. This system allows for the delivery of fuel to the engine at a desired flow rate under normal operating conditions. Additionally, there is a second controlled variable-restriction valve that enables the engine to be supplied with fuel at an adjustable, reduced flow rate in response to detecting over-speed or over-thrust of the engine.
Another significant patent by Varizat is related to aircraft engine fuel supply. This invention involves a centrifugal pump driven by mechanical coupling with an engine. It has a low-pressure inlet receiving fuel from a fuel circuit of an aircraft and a high-pressure outlet connected to a regulator circuit for regulating the flow rate of fuel supplied to the engine. An assistance pump unit, which is electrically controlled, is also included to ensure that fuel is delivered at a predetermined minimum pressure.
