Introduction

Donald W. Burns is a notable inventor based in Danville, IN (US). He has made significant contributions to the field of gas turbine engine technology, holding a total of 2 patents. His work focuses on enhancing the performance and stability of gas turbine engines through innovative bearing systems.

Latest Patents

One of his latest patents is for a combination bearing for gas turbine engines. This invention contemplates a combination bearing that supports a rotating rotor within a gas turbine engine. The combination bearing includes a magnetic bearing system and dry solid lubricated rolling element auxiliary bearing units for sharing the shaft load. The rotating central shaft is normally supported by the active electromagnetic bearing system. The auxiliary bearing unit is soft mounted to the shaft and engine housing, allowing for a stable transition from all magnetic bearing support to a physically contacting mechanically assisted support of the shaft.

Another significant patent by Burns involves magnetic bearings as actuation for active compressor stability control. This integrated system controls the positioning of a rotating rotor within a compressor to enhance the performance of a gas turbine engine. The rotor is attached to a rotating shaft that is coupled to the compressor housing by a magnetic bearing system. These magnetic bearings support and position the rotor within the high-speed turbomachine. During operation, the magnetic bearings non-axially position the rotor relative to the compressor housing, providing compressor instability control.
