2. Trolling motor - Wikipedia

   en.wikipedia.org/wiki/Trolling_motor

   A trolling motor is a self-contained marine propulsion unit that includes an electric motor, propeller and control system, and is affixed to an angler's boat, either at the bow or stern. A gasoline-powered outboard used in trolling , if it is not the vessel's primary source of propulsion, may also be referred to as a trolling motor.

3. 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 ...

4. Thrust-specific fuel consumption - Wikipedia

   en.wikipedia.org/wiki/Thrust-specific_fuel...

   TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rockets, etc.) is the mass of fuel needed to provide the net thrust for a given period e.g. lb/(h·lbf) (pounds of fuel per hour-pound of thrust) or g/(s·kN) (grams of fuel per second-kilonewton). Mass of fuel is used, rather than volume (gallons or litres) for the fuel ...

5. Pratt & Whitney J57 - Wikipedia

   en.wikipedia.org/wiki/Pratt_&_Whitney_J57

   The J57 (first run January 1950 [1]) was the first 10,000 lbf (45 kN) thrust class engine in the United States. It is a two spool engine. It is a two spool engine. The J57/JT3C was developed into the J52 turbojet, the J75/JT4A turbojet, the JT3D/TF33 turbofan , and the XT57 turboprop (of which only one was built). [ 2 ]

6. Specific impulse - Wikipedia

   en.wikipedia.org/wiki/Specific_impulse

   Thrust is the force supplied by the engine and depends on the propellant mass flow through the engine. Specific impulse measures the thrust per propellant mass flow. Thrust and specific impulse are related by the design and propellants of the engine in question, but this relationship is tenuous: in most cases, high thrust and high specific ...

7. Honeywell T55 - Wikipedia

   First experimental high-bypass turbofan engine produced in the United States, initially run in February 1964; two produced; used the engine core of the T55-L-7; [13] 40 in diameter (100 cm) geared fan stage, producing a static thrust of 4,320 lb (1,960 kg); predecessor of the ALF 502 and LF 507 production turbofans; [14] bypass ratio of 6:1 ...
