List of Items Controlled
Related Controls: Items described in 9A106.a, .b, and .c are “subject to the ITAR” (see 22 CFR parts 120 through 130).
Related Definitions: N/A
Items: a. Ablative liners for thrust or combustion chambers;
b. Rocket nozzles;
c. Thrust vector control sub-systems;
Technical Note:
Examples of methods of achieving thrust vector control controlled by 9A106.c includes:
1. Flexible nozzle;
2. Fluid or secondary gas injection;
3. Movable engine or nozzle;
4. Deflection of exhaust gas steam (jet vanes or probes); or 5. Thrust tabs.
d. Liquid, slurry and gel propellant (including oxidizers) control systems, and “specially designed” “parts” and “components” therefor, designed or modified to operate in vibration environments greater than 10 g rms between 20 Hz and 2000 Hz.
Note:
The only servo valves, pumps and gas turbines controlled by 9A106.d, are the following:
a. Servo valves designed for flow rates equal to or greater than 24 liters per minute, at an absolute pressure equal to or greater than 7 MPa, that have an actuator response time of less than 100 ms;
b. Pumps, for liquid propellants, with shaft speeds equal to or greater than 8,000 rpm at the maximum operating mode or with discharge pressures equal to or greater than 7 Mpa; or
c. Gas turbines, for liquid propellant turbopumps, with shaft speeds equal to or greater than 8,000 rpm at the maximum operating mode.
e. Flight control servo valves designed or modified for use in “missiles” and designed or modified to operate in a vibration environment greater than 10g rms over the entire range between 20Hz and 2 kHz.
