Launch Vehicles
Beal Aerospace initially considered a rocket that used kerosene and liquid oxygen, but soon switched to kerosene fuel in combination with high concentration hydrogen peroxide oxidizer. This combination was selected in order to avoid the expense and complexity of cryogenic storage, and to reduce development costs. Kerosene was injected into the hot steam and oxygen exhaust products of catalytically decomposed hydrogen peroxide, resulting in spontaneous ignition. The original BA-1 launch vehicle design was intended to service the LEO (Low Earth Orbit) satellite constellation launch market, but was replaced by the much larger BA-2 design when it was decided to concentrate on the more stable Geostationary satellite launch market as the LEO constellations became financially unsound. All three stages of the BA-2 vehicle were to be pressure-fed using high-pressure helium storage to replace the expense and complexity of turbopumps. All of the BA-2 propellant tanks and primary structures were to be manufactured from lightweight composite materials. The engines were self-cooled with ablative materials.

Famous quotes containing the words launch and/or vehicles:
“Now launch the small ship, now as the body dies
and life departs, launch out, the fragile soul
in the fragile ship of courage, the ark of faith
with its store of food and little cooking pans
and change of clothes,”
—D.H. (David Herbert)
“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
