AIRPLANE DESIGN

UAV Design:
- Flying Wing Research and Design:
  - Design of an unconventional reconnaissance U.A.V. The study yielded a successful radio controlled flying wing. The 2.4 meters span flying wing flew successfully in April’99 and performed numerous acrobatic maneuvers such barrel-rolls, hammer heads and loops without the aid of any computer augmentation control.
    - Final Presentation Aircraft Design.
    - Videos: Compilation, Barrel-roll-1, Barrel-rol-2, flyby, loop, touch-and-go1, touch-and-go2, touch-and-go3, touch-and-go4
