Latest Patents

One of Petsche's latest patents is an "Assembly for thermal shielding of low pressure turbine." This invention features a thermal seal and insulating assembly designed for the low pressure turbine stage of a gas turbine engine. The assembly includes an inner liner and an outer liner connected by a 360-degree ring, which serves to insulate the low pressure turbine case from high-temperature fluid flow. The inner liner is integrally connected to a liner extension that deflects thermal fluid flow away from it. Additionally, the assembly houses a plurality of tubular and axially aligned honeycombed cells that provide a barrier against radiation heat transfer.

Another significant patent by Petsche is the "Blade tip clearance control apparatus using bellcrank mechanism." This apparatus includes a positioning mechanism that controls the clearance between rotor blade tips and a shroud segment of a gas turbine engine casing. The mechanism is supported by the casing and is actuatable to move the shroud segment toward and away from the rotor blade tips, establishing the desired clearance. The design incorporates a shaft and a bellcrank actuating assembly, allowing for precise control of the rotor blade tips' positioning.
