Introducing the HFV-3X, AeroRocket's version of the DARPA HTV-3X known as the Blackswift  represents AeroRocket's proposal for a new hypersonic spacecraft capable of flight to 300,000 feet and top speed from Mach 5 to Mach 10. A miniature subsonic wind tunnel model of the new HFV-3X has been fabricated for experimental determination of CD, CL, CLa, CMa and L/D for use with AeroWindTunnel a subsonic and supersonic aircraft design program. Supersonic drag and lift properties of the HFV-3X design will be investigated using AeroRocket's new shock tube wind tunnel system.

SUBSONIC WIND TUNNEL
The AeroRocket subsonic wind tunnel is a suction system powered by a two speed 1/3 horsepower fan. The test section is 7 inches wide x 10 inches high x 16 inches long. A research quality pitot tube measures the difference between static and dynamic pressure in the test section. The resulting differential determines flow velocity using an analog velocity meter. Small models that represent large designs are routinely tested in the AeroRocket wind tunnel.

SUPERSONIC SHOCK TUBE  WIND TUNNEL
The AeroRocket shock tube (supersonic) wind tunnel performs drag and lift measurements from Mach 1 to Mach 5. The shock tube is 21 feet long or 26 feet long depending on specific Mach number requirements. This system is operational for supersonic wind tunnel testing. Also, AeroRocket's unique expertise in the fabrication of miniature supersonic wind tunnel models allows testing realistic shapes for accurate flow field and CD measurements for a wide variety of R&D applications, including the HFV-3X.
