ARC's LEROS 1C Apogee Engine Successfully Flown.Business Editors/High Tech Writers NOTE TO MEDIA: Photo is available in a Smart News Release(TM) on Business Wire's Home Page at www.businesswire.com GAINESVILLE, Va.--(BUSINESS WIRE)--June 26, 2000 Atlantic Research Corporation's (ARC) LEROS 1C Liquid Apogee Engine has successfully performed orbit-raising maneuvers for two A2100 satellites built by Lockheed Martin Space Systems Lockheed Martin Space Systems is one of the 4 major business divisions of Lockheed Martin. It is headquartered in Denver, Colorado. From a rich history of major companies Lockheed Martin has brought them together to offer design, integration, and production of: The LEROS 1C engine uses a conventional columbium columbium (kəlŭm`bēəm), symbol Cb, former name of the chemical element niobium. chamber with hydrazine hydrazine (hī`drəzēn'), chemical compound, formula NH2NH2, m.p. 1.4°C;, b.p. 113.5°C;, specific gravity 1.011 at 15°C;. It is very soluble in water and soluble in alcohol. and nitrogen tetraoxide as propellants. It delivers a specific impulse Specific impulse The impulse produced by a rocket divided by the mass mp of propellant consumed. Specific impulse Isp is a widely used measure of performance for chemical, nuclear, and electric rockets. in excess of 325 seconds, which is up to 10 seconds higher than other engines of its class. This increased performance offers significant advantages, including increased payload capability, longer on-station life, and reduced launch costs. The LEROS 1C was developed and manufactured by ARC UK Ltd. located in Westcott, England. The LEROS 1C is the third generation in the successful LEROS 1 engine series, of which over 45 engines have been flown on various communications satellites and interplanetary missions. ARC UK Ltd. is currently developing the LEROS 1D apogee engine, designed to deliver specific impulse in excess of 330 seconds. Development is also proceeding on an advanced 5-lbf attitude control thruster, the LEROS 20Ha, which will use the same propellants as the LEROS 1C and 1D apogee engines. Both programs are co-funded by the European Space Agency European Space Agency (ESA), multinational agency dedicated to the promotion, for exclusively peaceful purposes, of cooperation among European states in space research and technology. and are part of ARC's continuing commitment to provide advanced engines to the space industry. ARC, a unit of Sequa Corporation, is a leading developer and producer of solid propellant solid propellant n.
