2. Solenoid (engineering) - Wikipedia

   en.wikipedia.org/wiki/Solenoid_(engineering)

   The solenoid can be useful for positioning, stopping mid-stroke, or for low velocity actuation; especially in a closed loop control system. A uni-directional solenoid would actuate against an opposing force or a dual solenoid system would be self cycling. The proportional concept is more fully described in SAE publication 860759 (1986).

3. Solenoid valve - Wikipedia

   en.wikipedia.org/wiki/Solenoid_valve

   A direct-acting solenoid valve typically operates in 5 to 10 milliseconds. Pilot-operated valves are slightly slower; depending on their size, typical values range from 15 to 150 milliseconds. [2] Power consumption and supply requirements of the solenoid vary with application, being primarily determined by fluid pressure and orifice diameter.

4. Solenoid - Wikipedia

   en.wikipedia.org/wiki/Solenoid

   A finite solenoid is a solenoid with finite length. Continuous means that the solenoid is not formed by discrete coils but by a sheet of conductive material. We assume the current is uniformly distributed on the surface of the solenoid, with a surface current density K ; in cylindrical coordinates : K → = I l ϕ ^ . {\displaystyle {\vec {K ...

5. Model rocket motor classification - Wikipedia

   en.wikipedia.org/wiki/Model_rocket_motor...

   The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...

6. Electrohydraulic servo valve - Wikipedia

   en.wikipedia.org/wiki/Electrohydraulic_servo_valve

   The servo valves of the World War II-era were similar to this — using a solenoid to drive a spool valve. Advancement of EHSVs took off in the 1950s, largely due to the adoption of permanent magnet torque motors as the first stage (as opposed to solenoids).

7. Radio-controlled aircraft - Wikipedia

   en.wikipedia.org/wiki/Radio-controlled_aircraft

   Micro-sized 3D plane. Park flyers are small, primarily electric-powered planes, so named because their size enables some of them to be operated within the confines of a large public park. The smallest park flyers are called micro planes, and are slow and docile enough to fly within an enclosed area such as a gymnasium or even a living room.
