Most aircraft engineers, tasked with designing a new STOL aircraft, wouldn’t opt to drill 160,000 holes in the wing and utilize two piston engines to drive a single pusher propeller.
But then again, most engineers aren’t Jim Bede.
Bede XBD-2: Experimental Prototype for Unique Technologies
The clean-sheet aircraft design sought to improve aerodynamics by incorporating its twin engines in the aft fuselage.
Key Takeaways:
- Jim Bede's experimental XBD-2 aircraft featured several unconventional designs, including two fuselage-mounted piston engines driving a single pusher propeller for aerodynamic efficiency.
- It integrated a Boundary Layer Control (BLC) system with 160,000 pinholes in the wing, significantly lowering the stall speed from 64 mph to 42 mph.
- The aircraft also incorporated a shrouded propeller, claimed to drastically increase static thrust and reduce noise, contributing to impressive STOL performance.
- Despite its innovative technologies and performance, the XBD-2 remained a proof-of-concept, and its unique systems were not carried forward into Bede's subsequent aircraft designs.
