Tripoli Rocketry Association
The Tripoli Rocketry Association (TRA) is an international organization and one of the two major organizing bodies for high power rocketry in the United States. History Tripoli Rocketry Association was founded in 1964 in the Pittsburgh, Pennsylvania, region as a high school science club, integrating both rocketry and space science. The name "Tripoli" was chosen because the founding members came from three different towns, and one of them helped fund the club's early projects using gold coins that his father had brought back from Tripoli (whose name approximately means "three towns") Lebanon after World War II. By the late-1980s, it transitioned from a regional club into formal, incorporated, USA-national organization, with a focus on self-regulating advanced, High-Power Rocketry (HPR). The deregulation of the aviation industry by the Reagan Administration also facilitated the growth of HPR activities. The founder was Francis G. Graham. Early members who helped expand the clu ...

Non-profit Organization
A nonprofit organization (NPO), also known as a nonbusiness entity, nonprofit institution, not-for-profit organization, or simply a nonprofit, is a non-governmental (private) legal entity organized and operated for a collective, public, or social benefit, as opposed to an entity that operates as a business aiming to generate a Profit (accounting), profit for its owners. A nonprofit organization is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. Depending on the local laws, charities are regularly organized as non-profits. A host of organizations may be non-profit, including some political organizations, schools, hospitals, business associations, churches, foundations, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be Tax exemption, tax-exempt, and some may also qualify to receive tax-deductible contributions, but an enti ...

High Powered Rocket
High-power rocketry is a hobby similar to model rocketry. The major difference is that higher impulse range motors are used. The National Fire Protection Association (NFPA) definition of a high-power rocket is one that has a total weight of more than and contains a motor or motors containing more than of propellant and/or rated at 160.1 Newton-seconds (40.47 lbf·s) or more of total impulse, or that uses a motor with an average thrust of or more. Types High-power rockets are defined as rockets flown using commercially available motors ranging from H to O class. In the U.S., the NFPA1122 standard dictates guidelines for model rocketry, while NFPA1127 is specific to high-power rockets. In most U.S. states NFPA1122 has been adopted as part of the legal code. A smaller number of states use NFPA1127. Associations The Tripoli Rocketry Association and the National Association of Rocketry are the major sanctioning bodies for the hobby in the US, providing member certifications, and cr ...

Ammonium Perchlorate Composite Propellant
Ammonium perchlorate composite propellant (APCP) is a solid rocket propellant. It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by being cast into shape, as opposed to powder pressing as with black powder. This provides manufacturing regularity and repeatability, which are necessary requirements for use in the aerospace industry. Uses Ammonium perchlorate composite propellant is typically for aerospace rocket propulsion where simplicity and reliability are desired and specific impulses (depending on the composition and operating pressure) of are adequate. Because of these performance attributes, APCP has been used in the Space Shuttle Solid Rocket Boosters, aircraft ejection seats, and specialty space exploration applications such as NASA's Mars Exploration Rover descent stage retrorockets. In addition, the high-power rocketry community regularly uses APCP i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
