Bio-Inspired Rotating Empennage (BIRE) - Demonstration Model
Jacob McFall
Introduction / Motivation:
A concept fighter aircraft is being investigated by the Air Force Research Labs that eliminates the vertical tail and uses a bio inspired rotating empennage (BIRE). The motion of the empennage is intended to mimic the agile flight displayed by birds of prey. The removal of the vertical tail will both decrease the weight of the aircraft and significantly reduce the radar signature. Only theoretical design models exist with no available demonstration model
Product Development:
Traditional Structure
Original Research design used; parts modified for ease of printing
Topographically Optimized Structure
New researched framework used printing whole frame as one piece
3D Printing Technology Used:
Bambu Labs Carbon X1 Printer used for both models
Traditional Structure
Frame broken into layers, printed in one batch to avoid support and save material
Topographically Optimized Structure
Empennage frame and Fuselage frame kept as one piece to simplify printing and assembly
