Honeywell, Pratt and Whitney contracted by Air Force for power system support
by Stephen Carlson
Washington (UPI) Jul 13, 2017


Honeywell International and Pratt and Whitney have received requirements contracts totaling $27 million for engineering and research and development on secondary power systems for multiple platforms of the U.S. Air Force.

The twin contracts, announced Wednesday by the Department of Defense, will cover much of the U.S. Air Force's existing air fleet.

The companies have been tasked with the development of improved safety, reliability, and lower operating costs on the secondary powers systems of F-15, F-14, and A-10 fighters, alongside B-1 and B-2 bombers, and the C-130 and C-5 cargo planes and KC-135 tanker.

Honeywell and Pratt and Whitney will conduct the work at East Hartford, Conn., and Phoenix, Ariz., with completion of the project expected by July 11, 2025. No funds have been obligated yet for either company.

Maintaining and upgrading the secondary power systems is vital to keeping older legacy aircraft viable toward the end of their service lives.

Secondary power systems are a key part of the modern power plants on aircraft. They serve two main purposes -- starting the aircraft's engines with the aid of a start cart,and then transmitting power to the aircraft's other systems once the engine's operation is self-sustaining.

Global warming may limit airplane takeoffs in coming decades
Washington (UPI) Jul 13, 2017
As climate change brings high temperatures around the globe, new research suggests some airplanes could struggle to takeoff. Airplane wings generate less lift in thin air. Warmer air is thinner air, as molecules in the atmosphere move farther apart as they heat up. Thus, during extremely hot portions of the day, some plane models may need to dump weight - whether fuel, cargo or ... read more
