Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ISO 1585.
If Imperial units are used, and if torque is in pounds-force feet and rotational speed in revolutions per minute, the above equation gives power in foot pounds-force per minute. The horsepower form of the equation is then derived by applying the conversion factor 33,000 ft⋅lbf/min per horsepower:
One metric horsepower is needed to lift 75 kilograms by 1 metre in 1 second. Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity.
The tax horsepower rating was computed not from actual engine power but by a mathematical formula based on cylinder dimensions. At the beginning of the twentieth century, tax power was reasonably close to real power; as the internal combustion engine developed, real power became larger than nominal taxable power by a factor of ten or more.
Power 115 hp (86 kW) at 2800 rpm, dry weight 247 lb (112 kg) Similar to O-235-C2A but with two S-1200 series magnetos. [2] O-235-C2C Power 108 hp (81 kW) at 2600 rpm, alternate rated maximum continuous power rating of 100 hp at 2400 rpm, dry weight 244 lb (111 kg) Similar to O-235-C2B except with Slick magnetos and shielded ignition harness.
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific.
The six-seat CitationJet is a monoplane with a cantilever wing, a retractable tricycle landing gear and a pressurized cabin.. The jet uses the Citation II's forward fuselage, a new carry-through section, a new laminar flow, supercritical wing developed with NASA and Boeing, and a T-tail.
