Patent number: 11878810Abstract: Auxiliary power systems, aircraft including the same, and related methods are disclosed herein. In one embodiment, the aircraft includes an airframe and an auxiliary power system that includes an auxiliary power unit (APU), an APU controller, and a bleed air temperature (BAT) sensor. The APU defines a bleed air outlet and is configured to regulate a BAT of a bleed air flow generated by the auxiliary power unit. The BAT sensor is positioned at a remote BAT location that is outside the bleed air outlet of the APU. In another embodiment, the auxiliary power system includes an APU configured to generate a bleed air flow, an APU controller configured to receive and transmit signals, and a BAT sensor suite configured to measure the BAT of the bleed air flow and to generate a BAT signal that is based, at least in part, on the BAT.Type: GrantFiled: March 18, 2022Date of Patent: January 23, 2024Assignee: The Boeing CompanyInventors: Scott Schorn, John Carl Szillat, David Scott Krug, Paul R. Tretow, Keith Douglas Choyke, Royal E. Boggs, Angela O'Gorman

Patent number: 11279490Abstract: Auxiliary power systems, aircraft including the same, and related methods. An auxiliary power system comprises an auxiliary power unit (APU) controller and an APU with an air intake, a powerhead, and a load compressor stage. The load compressor stage includes a flow regulator assembly, a load compressor, and a bleed air temperature (BAT) sensor for generating a BAT signal. The APU controller regulates a flow rate of a load compressor airflow through the load compressor based on the BAT signal. A method of utilizing an auxiliary power system includes compressing a load compressor airflow to generate a bleed air flow, measuring the BAT with a BAT sensor, generating a BAT signal based on the BAT, transmitting the BAT signal to an APU controller, generating a flow regulator command with the APU controller, transmitting the flow regulator command to a flow regulator assembly, and controlling a flow regulator assembly.Type: GrantFiled: January 3, 2019Date of Patent: March 22, 2022Assignee: The Boeing CompanyInventors: John Carl Szillat, David Scott Krug, Paul R. Tretow, Scott Schorn, Royal E. Boggs, Keith Douglas Choyke

Patent number: 11041501Abstract: A method for controlling compressed air sent to pneumatic systems. The method includes acquiring a set of performance demands for each of a plurality of pneumatic systems in a platform, where the performance demands indicate needs for the compressed air supplied to each of the pneumatic systems, identifying a maximum allowable air discharge temperature limit of a variable speed air compressor configured to supply compressed air to the pneumatic systems, and controlling an operation of the compressor to supply the compressed air to the pneumatic systems to meet the acquired performance demands for at least one of the pneumatic systems while operating the compressor below the maximum allowable air discharge temperature limit.Type: GrantFiled: March 20, 2019Date of Patent: June 22, 2021Assignee: The Boeing CompanyInventors: Warren A. Atkey, Steve G. Mackin, Royal E. Boggs, Hosam E. El-Gabalawy

Patent number: 10427796Abstract: An air distribution system and method for an air conditioning system in an air vehicle are provided. The air distribution system has lower lobe ducts below a cabin floor of a cabin of the air vehicle. Each lower lobe duct is in fluid communication with a mix manifold coupled to AC packs. The air distribution system further has sidewall riser ducts, outboard manifold ducts, a recirculation air duct, and either recirculation downer ducts, or branch recirculation ducts coupled to the recirculation air duct. The air distribution system has a conditioned air flow, distributed to either the lower lobe ducts, or the lower lobe ducts and then the sidewall riser ducts; has a recirculated air flow, distributed to either the recirculation downer ducts or branch recirculation ducts; and has a mixed air flow distributed to the outboard manifold ducts, and into the cabin.Type: GrantFiled: March 31, 2017Date of Patent: October 1, 2019Assignee: The Boeing CompanyInventors: Annika E. Carden, Royal E. Boggs, Brian D. Hlavka, Sidney D. Shell
