H14ST-P 29mm x 230mm single-use DMS Disposable Motor System, long burn solid composite propellant, high-power hobby rocket motor - A081400
H14ST-P 29mm x 230mm single-use DMS Disposable Motor System, long burn solid composite propellant, high-power hobby rocket motor.
The new H14ST-P DMS high-power rocket motor was designed by Gary Rosenfield, RCS/AeroTech founder and president, after developing the H13ST-P for the Hamster Dance competition at Black Rock Desert, NV during the BALLS-28 launch. The new H14ST-P is capable of reaching altitudes over 20,000 feet with an 18.3 second burn time. This low-thrust, long burn high-power hobby rocket motor has the highest total-impulse of any 29mm long burn high-power rocket motor available.
The H14ST-P is offered in two versions, with a built-in thrust ring (P/N 081400) and without (P/N 081400NTR). This is a great rocket motor for both heavier gliders and lighter weight, high altitude rockets as a single-stage or upper stage low thrust / long burn propulsion system. Featuring AeroTech’s fast-burning Super Thunder propellant formulation, the H14ST-P delivers a sharp high-thrust spike followed by a reduced sustain thrust for the remainder of the burn.
The H14ST-P delivers 240.12 N-sec (53.98 lb.-sec) of total-impulse with a peak thrust of 42.13 N (9.35 lbs.). This is a “plugged” motor that does not produce delay smoke or contain any ejection charge. Rockets using this type of rocket motor must utilize an electronically-activated recovery system.
The AeroTech Disposable Motor System DMS is a single-use motor in kit form that is assembled by the user. All of the Aerotech DMS motors use all-disposable components. The nozzle and propellant are already installed.
The H14ST-P is a Plugged/Smoke motor. Plugged reload kits do not utilize a motor-actuated ejection charge. Plugged motors must be used in conjunction with a timer, altimeter or radio-activated recovery system. The motor case includes the thrust ring.
DMS motors feature a filament-wound fiberglass casing, a glass-reinforced composite phenolic nozzle, a molded plastic bulkhead and RCSs exclusive Super Thunder™ aerospace grade composite propellant formulation, which produces a bright violet-blue flame with a minimum of exhaust smoke. Super Thunder™ motors provide a higher ISP than Blue Thunder™.
This AeroTech motor pack comes with 1 rocket motor and 1 FirstFire™ Initiator. Requires HAZMAT shipping via UPS or FEDEX.
