Bombardier Aerospace has confirmed that a new bleedless APU it is developing with Microturbo (Safran), Thales and Saft, has successfully started after a 10-hour soak at -40°F. The prototype e-APU uses a starter/generation system and lithium-ion battery system and has been designed for use on business jets.
The tests were conducted at the Turbomeca's (Safran) cold chamber facility in Pau, France, and were a first in the aerospace industry, according to Bombardier.
When in use, the new technology will reduce fuel use and carbon emissions due to its lower weight, longer lifecycle and unrestricted operation at extremely low temperatures, claims the Canadian firm. It will also simplify aircraft manufacturing and assembly, and lead to reduced maintenance costs, according to Bombardier
