Test Stand 403

[image-51]Test Stand 403 is a 32 ft diameter by 33 ft high (9.75 m diameter by 10 m high) carbon steel altitude chamber, capable of accommodating a vehicle with a thrust vector controlled, 110-kN-thrust engine firing vertically downward. It can test articles of 15 ft by 15 ft by 45 ft tall (4.6 m by 4.6 m by 13.7 m tall). It consists of three interior levels which can be reconfigured to meet test requirements.


  • Single-position, vertical firing capability
  • Altitude test capability to 100 K ft (30.5 km) for engine firing with steam system; up to 250 K ft non-firing with vacuum pumps
  • Propellants: N2O4 & Hydrazines
  • Propellant capability - 2000-gal storage/run tanks for hypergolic propellants (MMH/N2O4) can be saturated with helium up to 300 psi; both propellants can be temperature conditioned from 40 to 120 °F (4 to 49 °C); pressure or pump transfer of propellants; two propellant aspiration systems installed
  • Maximum thrust - 25 K lbf (111 N); vertical firing; screw-jack precision test article positioning system; ambient pressure-temperature conditioning from 30 to 120 °F (-1 to 49 °C)
  • Low-pressure cryogenics: 28,000 gal liquid hydrogen, 13,500 gal liquid oxygen, vacuum-jacked feed lines
  • 400-ft3 (11 m3) gaseous oxygen at 3000 psi
  • 500-gal, 600-psi hydrocarbon fuel system (currently ethyl alcohol)
