The National Fire Protection Association (NFPA) definition of a high-power rocket is one that has a total weight of more than 1,500 grams (3.3 lb) and contains a motor or motors containing more than 125 grams (4.4 oz) of propellant and/or rated at more than 160 Newton-seconds (40.47 lbf·s) of total impulse, or that uses a motor with an average ...
Patrick Laverty - altitude world record: 5,348 metres (17,546 ft), U.K., May 24, 2009 On May 24, 2009, Irish pilot Patrick Laverty broke the foot-launched powered hang glider altitude world record. He used an Aeros Discus 15 hang glider coupled to a supine custom-made harness equipped with a 29 hp ROS 125 engine with the Supa-Tuna tuning lights ...
Model rocketry is a safe and widespread hobby. Individuals such as G. Harry Stine and Vernon Estes helped to ensure this by developing and publishing the NAR Model Rocket Safety Codes [1] [13] [14] and by commercially producing safe, professionally designed and manufactured model rocket motors.
Amateur rocketry, sometimes known as experimental rocketry or amateur experimental rocketry, is a hobby in which participants experiment with fuels and make their own rocket motors, launching a wide variety of types and sizes of rockets.
The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...
XRS-2200 linear aerospike engine for the X-33 program being tested at the Stennis Space Center. The aerospike engine is a type of rocket engine that maintains its aerodynamic efficiency across a wide range of altitudes. [1]
The suborbital X-15 and a companion training aero-spacecraft, the NF-104 AST, both intended to travel to an altitude that rendered their aerodynamic control surfaces unusable, established a convention for locations for thrusters on winged vehicles not intended to dock in space; that is, those that only have attitude control thrusters. Those for ...
