Hypersonic Flight Demonstration (HyFly)

Program Manager: Dr. Thomas Bussing

Overview

The Hypersonics Flight Demonstration program (HyFly) developed and demonstrated advanced technologies for hypersonic flight. The ultimate goal of the program was to demonstrate vehicle performance that could lead to an operational tactical surface launched missile range of 600 nautical miles. Specifically, the program demonstrated an F-15 launched missile configuration with a range of 400 nautical miles, a maximum sustainable cruise speed in excess of Mach 6, and the ability to accurately terminate the missile on a GPS guided impact target. Technical challenges included the scramjet propulsion system, lightweight, high-temperature materials for both aerodynamic and propulsion structures, and guidance and control in the hypersonic flight regime. Recently demonstrated performance in ground testing of the dual combustion ramjet engine coupled with advances in high temperature, lightweight aerospace materials were enabling technologies for this program. The core program focused on development and demonstration of capabilities requisite for an operational weapon.
