Weight Engineering - System Design %X The mass properties are identified for a plane that is an ‘aerospace’ plane in the literal sense in that it can take off at sea level and fly on a ballistic trajectory above the atmosphere. The vehicle is tactical in nature, as opposed to logistical, having a crew of two and a payload limited to under-wing missiles. The configuration is dominated by the engine duct which makes up the main body airframe. The propulsion system is made up of a traditional jet engine mounted in the forward end of the duct and a JP rocket engine mounted aft. Annulus space around the two engines serves as area cross-section for ramjet operation. Structure and thermal protection are modeled after the X-15 rocket plane that flew on a ballistic trajectory to Mach 6.7 and an altitude of 150,000 ft. %B 64th Annual Conference, Annapolis, Maryland %I Society of Allied Weight Engineers, Inc. %C Annapolis, Maryland %P 13 %8 5/14/05 %G eng %U https://www.sawe.org/papers/3364/buy %9 24.
