Ram Air Turbine (RAT)
You’ll note a donated Ram Air Turbine (RAT) display which was made possible with assistance of UTAS, the manufacturer of 604’s RAT.
Due to it being one of the most asked about aspects at the Exhibit, the RAT display is being enhanced. The display content will be expanded with help from the engineer involved in the initial B-767/757 joint RAT development programs. We also now have acquired 604’s original RAT fuselage Powerpoint presentation . Additionally we have on display the 604 fuselage RAT door.
One member of the RAT development team said to us “At the time of the 767 & 757 co-development, this RAT turbine was of a novel and new design that had a number of innovative features that made it both more reliable and cost-effective. This design approach, the first of its kind, has gone on to be the standard for essentially all modern RAT’s since that time including those used on Airbus, Embraer, Bombardier, and military transport aircraft. To my knowledge there have been at least 17 verified aircraft “saves” with something around 2600 lives saved due to this piece of safety equipment.”
We’ve also learned that back then, some propulsion engineers were of the opinion that the RAT was not needed and would never be used
