Thiokol solid rocket engine. 0.166 kN. In Production. Isp=249s. Space Gnat was designed to provide a minimum acceleration, extended burn delta-V impulse, for small payload replacement or spin-up applications.

With a low average thrust and a unique off-center nozzle design, the motor can be utilized in many nonstandard geometric configurations for small payload replacement or spin-up applications. As with most STAR motors, the STAR 5A has been demonstrated to allow a 20 percent offload capability. The STAR 5A is typical of Elkton DLV division's quick response to small motor needs as it was designed, qualified, and delivered in 10 months. Total impulse 584 kgf-s. Propellant mass fraction 0.493.

AKA: 32.02-KS-38; TE-M-863-1; Space Gnat.
Status: In Production.
Gross mass: 4.60 kg (10.10 lb).
Unfuelled mass: 2.33 kg (5.13 lb).
Diameter: 0.13 m (0.43 ft).
Thrust: 166 N (37 lbf).
Specific impulse: 250 s.
Burn time: 32 s.
Number: 8 .

Associated Propellants
  • Solid Solid propellants have the fuel and oxidiser embedded in a rubbery matrix. They were developed to a high degree of perfection in the United States in the 1950's and 1960's. In Russia, development was slower, due to a lack of technical leadership in the area and rail handling problems. Solid propellants have the fuel and oxidiser embedded in a rubbery matrix.
