Super Loki Motor Assembly- Single (w/out Dart fins)
Product Code: SLMA-1
Super Loki Motor Assembly- Single (w/out Dart fins) Summary
ALSO, FOR A LIMITED TIME AND WHILE SUPPLIES LAST, ALL SUPER LOKI ROCKET MOTOR ASSEMBLY ORDERS WILL INCLUDE A LOKI DART (WITHOUT DART FINS)(A $500 VALUE) AT NO EXTRA CHARGE! THIS IS A COMBINED $2,000 VALUE!
OWN A PIECE OF U.S. SPACE PROGRAM HISTORY!
RCS has a limited number of unused, unloaded Super Loki rocket motor assemblies available. The Super Loki motor assembly consists of a high-strength aluminum alloy casing, graphite nozzle, steel nozzle retainer (all preassembled), four aluminum fins spot welded to the casing and a match-drilled forward bulkhead. The forward bulkhead is designed to be retained in the casing with spring pins (not included).
While supplies last, customers who purchase a Super Loki motor assembly will also receive a casting mandrel assembly at no extra charge!
The forward bulkhead was retained in place with 36 spring pins, the equivalent McMaster part no. is 98296A959. A drawing of the pins can be downloaded by clicking here.
Super Loki motor assembly specifications:
O.D.: 4.00"
I.D.: 3.834"
Length: 78.5"
Empty weight: 11.6 lb
Super Loki performance specifications when loaded:
Propellant weight: 37.2 lb
Loaded weight: 48.8 lb
Total impulse at sea level: 8,900 lb-sec (39,587 N-sec)
Specific impulse at sea level: 239 sec.
Maximum chamber pressure: 1,470 PSI
Average chamber pressure: 1,230 PSI
Burnout velocity when flown at sea level: nearly 6,000 FPS
Maximum altitude of dart when flown at sea level: 372,000 feet (70.5 miles/113.4 km)
Industrial Solid Propulsion (ISP), Inc. loaded around 200 Super Loki and Viper 3A motors for Orbital Sciences Corp. in the 1990s. ISP developed an analog HTPB propellant formulation (designated "8522") to replace the original Polysulfide formulation. The simplified formulation using current RCS ingredients is:
80.40% RCS 200 micron AP blend
0.70% RCS Copper Chromite
1.80% 4 micron Aluminum
2.00% Potassium Perchlorate
9.88% RCS HTPB
0.10% RCS CAO-5
3.78% RCS IDP
1.35% RCS Modified MDI Isocyanate Curative
8522 propellant ballistic properties:
Burn rate coefficient 'a' = 0.027
Burn rate exponent 'n' = 0.405
Density = 0.06087 lb/in3
Gas molecular wt. = 25.278
Stagnation temperature = 5429 deg. R
Gamma = 1.216
The motor was lined with 250 grams of an HTPB-based formulation which consisted of:
143.8 grams RCS HTPB
1.0 grams LICA-38 Titanate
1.0 grams RCS CAO-5
10.0 grams Lampblack
50.0 grams Trichloroethane
44.2 grams RCS Modified MDI Isocyanate Curative
The material was poured into the case, swabbed around the interior and allowed to cure horizontally while rotated on a drum roller for 24 hours.
