linear aerospike engine การใช้

• The RS-2200 Linear Aerospike Engine was derived from the XRS-2200.
• In fact, a linear aerospike engine was used in the X-33 design.
• The power plant is a linear aerospike engine that adjusts itself to perform with maximum efficiency at all altitudes.
• And it is developing the linear aerospike engine for the X-33 vehicle that may replace the shuttle and an airborne laser weapon system.
• The linear aerospike engines are supposed to save weight and complexity by forgoing the movable, bell-shaped engine nozzles used for conventional rocket engines.
• The 18-second test of what is known as a linear aerospike engine was carried out on Dec . 18 at a NASA center in Mississippi.
• The rocket, and eventually the Venture Star, is to be powered by linear aerospike engines, which promises to be more efficient than conventional ones.
• The X-33 and its successor are to be powered by linear aerospike engines, which save weight and complexity by forgoing the moveable, bell-shaped engine nozzles used for conventional rocket engines.
• Furthermore, design specifications called for the use of linear aerospike engines that maintain thrust efficiency at all altitudes, whereas the Shuttle relied upon conventional nozzle engines which achieve maximum efficiency at only a certain altitude.
• The X-33 and the proposed Venture Star are wedge-shaped, flat-bottomed craft with wide rectangular tail ends, ideal for lining up a row of linear aerospike engines that smoothly integrate into the shape of the vehicle, their designers say.
• The X-33 did create some valuable technologies, Stephenson said, among them the creation of the linear aerospike engines built by Boeing's Rocketdyne division in Canoga Park, new advanced thermal protection, and " self-healing " electronic instruments.
• _X-33 : 67 feet ( 20.4 meters ) tall, 68 feet ( 20.7 meters ) wide at base, gross liftoff weight of 273, 000 pounds ( 124, 000 kilograms ), two linear aerospike engines, payload bay 5 feet by 10 feet ( 1.5 meters by 3 meters ).
• _Full-scale operational vehicle : 127 feet ( 38.7 meters ) tall, 128 feet ( 39 meters ) wide at base, gross liftoff weight of 2.18 million pounds ( 990, 000 kilograms ), seven linear aerospike engines, payload bay 15 feet by 45 feet . ( 4.6 meters by 13.7 meters ).
