The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters developed in the late 1980s and used since 1990. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant.
All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories: Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants , typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder.
TRW Inc. was an American corporation involved in a variety of businesses, mainly aerospace, electronics, automotive, and credit reporting. [2] It was a pioneer in multiple fields including electronic components, integrated circuits, computers, software and systems engineering.
The carrier aircraft (initially a NASA B-52, now an L-1011 owned by Northrop Grumman) serves as a booster to increase payloads at reduced cost. 12,000 m (39,000 ft) is only about 4% of a low Earth orbital altitude, and the subsonic aircraft reaches only about 3% of orbital velocity, yet by delivering the launch vehicle to this speed and ...
As its name suggests, the Grumman LLV is easily capable of a long life. The required lifespan specified by the U.S. Postal Service was 24 years, but in 2009, this was extended to 30 years. The Grumman LLV can easily last over 200,000 miles on its original engine and transmission before needing an overhaul. [13] [14] 1987 LLV (left) and 2000 FFV ...
