Patent number: 7417337Abstract: An improved method and system for facilitating no-break power transfer between an APU and a main engine includes determining a required APU speed for conducting power transfer based on various APU operating parameters, such as engine speed, fuel, environmental temperature, etc. The APU controller then adjusts the APU speed up or down to the required APU speed. Communication between an aircraft computer and the APU controller may also be provided so that operational data can be exchanged to adjust the electrical load of the aircraft below a maximum load threshold set by the APU, avoiding overloading of the APU during power transfer. By exchanging operational data between the APU controller and the aircraft computer, both the APU and the electrical load can be adjusted to optimize no-break power transfer despite varying APU operating conditions and main engine generator frequencies.Type: GrantFiled: September 4, 2003Date of Patent: August 26, 2008Assignee: Hamilton Sundstrand CorporationInventor: Peter J.

Patent number: 7408327Abstract: The output voltage generated by permanent magnet generator (PMG) is regulated by controlling a buck/boost voltage applied to selected sub-coils within the PMG. The PMG includes a number of stator coils that are each divided into a number of sub-coils. A buck/boost voltage source generates a buck/boost voltage, and a controller connected to monitor the output voltage generated by the PMG selectively applies the buck/boost voltage to selected sub-coils based on the monitored output voltage. In this way, the controller is able to regulate the output voltage by selectively controlling the buck/boost voltage applied to the selected sub-coils.Type: GrantFiled: April 23, 2007Date of Patent: August 5, 2008Assignee: Hamilton Sunstrand CorporationInventors: Mahesh J.

Patent number: 7401588Abstract: A cylinder block for an axial piston pump or motor is formed from a steel material. The block includes a plurality of bores that each have an internal bore surface of a predefined final material surface finish. The bores are subjected to various machining and heat treating processes to provide a bore surface formed from the same material as the cylinder block, and which has the desired final surface finish. Pistons are mounted within each of the bores for axial movement relative to the cylinder block. Each of the pistons is formed from a steel material and has an exterior surface that is in sliding contact with the internal bore surface. The subject cylinder block is processed to provide a steel-to-steel interface between the bore and piston and eliminates the need for liners to be specially formed or installed within each piston bore.Type: GrantFiled: November 7, 2003Date of Patent: July 22, 2008Assignee: Hamilton Sundstrand CorporationInventor: Henry R.
