Auxiliary power unit

On the Boeing more-electric aircraft, the APU delivers only electricity to the aircraft.

Auxiliary power unit

During ascent, the APUs provided hydraulic power for gimballing of the Shuttle's three engines and control of their large valves, and for movement of the control surfaces.

Power available for battery charging and electrical accessories; 60 amp, 12 volt solid state. As the main engines are powered up, they take over the air conditioning and everything else, and the APU is typically shut down.

Power section[ edit ] The power section is the gas generator portion of the engine and produces all the shaft power for the APU. Note an electrical load may be used with no warm up period.

Power Management

Within the gearbox, power is also transferred to engine accessories such as the fuel control unit, the lubrication module, and cooling fan. The coked fuel on the fuel nozzle can result in hot streaks through the APU that can cause localized damage to the combustor and the first stage turbine nozzle and accelerates wear through the entire hot section.

Pony Pack: The Reliable Auxiliary Power Unit

For questions or comments, please use the information listed here. This unit operates independently of the truck Freon or cooling systems. The SOFC would use air from a compressor passed through a heat exchanger for its gas turbine section.

Here's why that's a problem. Noun For more information about the fundraiser, visit the GoFundMe page, or the auxiliary's website. Rather, when an airplane is parked at the gate, pilots will use the APU to power onboard electric systems—from cabin lights and coffee makers to various cockpit systems—as well as to provide airflow to the air conditioning systems.

With 2 packs supplying the cabin cooling requirements the pressure requirement is lower, resulting in lower turbine inlet temperatures, EGTs and far less unused air being discharged through the surge valve.

It concluded that the SOFC would have to improve its power to weight ratio by at least a factor of 2 to break even on power produced against the fuel burn to carry its increased weight over a conventional APU. But after a resplendent summer last year at Triple A Pawtucket and a winter of panegyrics from a giddy Boston press, first baseman Maurice Samuel Mo Vaughn, 23, has arrived as a "real" rookie who everyone in Red Sox-land hopes is the real thing.

The SOFC would use air from a compressor passed through a heat exchanger for its gas turbine section. Although much quieter than gas turbines, this could still be a problem at airports which require the APU to be shutdown during the turnaround for environmental reasons.The APU is a source of bleed air and AC electrics for the aircraft, this gives independence during turnarounds, electrical backup in the event of engine failure and provides air conditioning & pressurisation during an engine bleeds off take-off.
