Page "Beal Aerospace" Paragraph 3

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.
