Project: Quiet Spike
NASA F-15B #836 in flight with Quiet Spike attached. The project centered around a retractable, 24-foot-long lance-like spike mounted on the nose of NASA Dryden’s F-15B research testbed aircraft. The spike, made primarily of composite materials, created three small shock waves that traveled parallel to each other all the way to the ground, producing less noise than typical shock waves that build up at the front of supersonic jets.
