Hello All,
Below are illustrations of--and links to more illustrations of (and information on)--a new vehicle that would make a good (and unusual) scale model rocket. Orbital Sciences Corporation's GQM-163A Coyote is a sea-skimming supersonic target that is powered by a solid fuel ducted rocket/ramjet motor. Designed to simulate sea-skimming supersonic anti-ship missiles, the Coyote typically cruises at Mach 2.5 at an altitude of only about 15 feet above the sea surface. Its maximum speed is Mach 2.8. The vehicle is boosted to ducted rocket/ramjet ignition velocity by a solid propellant rocket booster from the Mark 70 Standard Missile.
A flying scale model of the Coyote could also utilize a ducted rocket system to augment the thrust of the model rocket (or HPR) rocket motor in its motor mount. Although the full-scale Coyote is designed for horizontal flight, its rocket-like configuration (with four fins [plus four rear winglets on later versions] and four ramjet air intake scoops located at the rear of the target) would make a scale model of the Coyote very stable in standard vertical and near-vertical model rocket (or HPR) ascents. Here are the links:
