The Honeywell 757 Flying Test Bed (FTB) is just one example in SIE’s long history of modifying  aircraft  that combine elegant form with utilitarian function.   The Honeywell 757 FTB is a tool that allows the  OEM to fully evaluate the prototype engine through all phases of the flight envelope.

Creation of the Honeywell 757 FTB by SIE involved extensive aerodynamic analysis, structural design elements, and systems development and integration.  

The SIE Team designed fuselage reinforcements, frame redesign, pylon support structure, and fairing design and sub-structure.  On the systems side, SIE designed the fuel, hydraulic, pneumatic, electrical, and FIRE-EX systems in support of the OEM’s engine flight test requirements.
