Brake horsepower - 14 CFR 1.1
Tags: 14 CFR 1.1, FAA, Regulatory
Brake horsepower means the power delivered at the propeller shaft (main drive or main output) of an aircraft engine.
Horsepower
By the American definition, one horsepower (HP) is the amount of energy required to lift 550 pounds one foot in one second, disregarding any friction.
Horsepower Loading
The ratio of gross wieght to horsepower, obtained by dividing the total weight by the engine′s horsepower rating.
Hovering in Ground Effect ...
HORSEPOWER - The motive energy required to raise 550# one foot in one second, friction disregarded.
HYPERSONIC - Speed of flight at or greater than Mach 5.0, exceeding SUPERSONIC.
Brake Horsepower. (Abbreviated b.h.p.) The Horsepower available at the propeller shaft of an aero engine. It differs from the Indicated Horsepower by the power needed to overcome the internal friction of the engine.

bhp - brake horsepower.
BHPA - British Hang Gliding and Paragliding Association.
Bleed air - Hot compressed air taken from turbine engines.
shp - shaft horsepower.
SID - standard instrument departure. A standard IFR departure route enabling air traffic controllers to issue abbreviated clearances and thus speed the flow of traffic.
Engine flywheel horsepower.
Engine fuel efficiency, commonly referred to as BSFC or Brake Specific Fuel Consumption.
Maximum fuel system pressure and the pump's flow volume at that pressure.
In order to climb, extra horsepower is required beyond that necessary for more horizontal flight. The machine can, for instance, fly at 56 miles per hour at which speed it requires 43 hp.
the later Ki 44 Type 2 Army Fighter, the Shioki or "Tojo".) Designer Hideo Itokawa, (who passed away in Feb 1999) undertook the difficult task of equaling the Ki 27's tight-turning and dogfighting qualities in a heavier 1,000 horsepower class ...
The engine used was the Wright R-2600-20 (which produced 1,900 horsepower). There were three crew members-pilot, turret gunner, and radioman/bombardier/ventral gunner. A .50-caliber machine gun was mounted in each wing, and one more .
Despite the massive injection of horsepower, the big Lycoming doesn't exactly foam at the mouth. Still, there's little question you're going someplace when you put the big knob against the panel.
By calculating this maximum and not exceeding it, the pilot derates the engine from the 160 horsepower which is actually available, to the derated maximum which is 124 horsepower continuous, or 131 horsepower for up to 5 minutes.
Maxim was adept at building lightweight steam engines, including one that produced 180 horsepower. He constructed a test track that would allow an aircraft to take off but would then keep it close to the track.
The Krogs soon became the proud parents of a 90-horsepower J-3 Cub. Steve decided that he wanted to share his pride and joy with as many pilots as he could, so he put the Cub to work and started taking on students, ...
The C-3, with only 37 horsepower and a lot of hope, could, if given enough time, lug a student and an instructor off the ground, and the first inexpensive trainer was born.
For a given thrust (engine horsepower, intake, exhaust and propeller) we want a high cruise speed, thus need low drag at high speed.
The traditional units for the vertical axis in this figure would be horsepower, but I have used feet per second instead. This is intended to clarify the equivalence of all four forms of energy by measuring them in a common set of units.
There are eight V- belts, tightened via an electric actuator, that connect the normally aspirated, 180-horsepower Lycoming HO-360-C1A engine to the transmission.
Piper Super Cub PA-18-150 is powered with Lycoming O-320 engine, with a rated horsepower of 150 at 2700 RPM.
This pumping process uses lots of horsepower and accelerates the air to relatively high velocities. Air velocity under the helicopter may reach 60 to 100 knots, depending on the size of the rotor and the gross weight of the helicopter.
It also was considered a safer plane, built of an aluminum alloy stronger than materials previously used in aircraft construction. It had more powerful engines (1,000 horsepower versus 710 horsepower for the DC-2), ...
Such aircraft can be single- or multi-engine. Turboprop engines are increasingly used when more horsepower is needed for speed or payload than the 300-400 horsepower available from current light-aircraft piston engines.
Engine wear and fuel savings can be achieved by reducing RPM and increasing manifold air pressure, MAP to maintain horsepower. Modern engines have approved power ranges for which this practice is allowed.
Edison reported that it would take a motor with a ratio of three to four pounds per horsepower produced to be successful, based on his experiments.
