Robinson is one of only two helicopter manufacturers employing piston engines (the other is Schweizer).
Piston Ring: A ring inset into the piston of an engine intended to preserve a gas-tight seal between the piston and the cylinder wall.

Piston engined aircraft have an advantage compared to turbine powered types, they make more noise thus warning the birds to get out of the way.
Piston helicopters also benefit because power available is directly proportional to RPM. If the engine is run at 95% of maximum allowable RPM, power available is 5% lower than if the engine is run at 100% of allowable RPM.

The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder full of air and gasoline. This is the intake stroke.
Multiengine Piston
These airplanes have two or more piston engines using propellers to drive the airplane.

Most early jets were designed like piston-engined fighters with straight wings, limiting their high speed performance.
BOXER OR BOXER ENGINE - Any horizontally opposed engine in which the corresponding pistons reach top dead center simultaneously, such as those found in most light general aviation aircraft.
The TB-3 had four 819 hp Mikulin AM-34-RN piston engines as power plants. It had a maximum speed of 152 mph-a major feat for this kind of unorthodox aircraft. The engines gave the TB-3 a climb rate of 410 ft/min. to 3,280ft.
It consists of a piston in a cylinder filled with both oil (“oleo”) and air (“pneuma”). Figure 10.5 shows the general idea. If the piston is moved up into the cylinder, the air at the top of the cylinder is compressed.
These engines use an aluminum piston, and a chrome or nickel plated brass sleeve. The engine is harder to turn over and start due to the tight fit between the piston and cylinder. This tight fit is what makes the engine more efficient, and powerful.
visual flight rules - Rules governing flight during periods of generally good visibility and limited cloud cover (i.e., a pilot's ability to fly and navigate by looking out the windows of the airplane), predominantly employed by piston-powered ...
TURBOPROP An airplane using a turboprop engine, a jet rather than piston engine connected to a propeller. Such aircraft can be single- or multi-engine.
The development of floats made floatplanes more popular than flying boats for small aircraft designs, since it allowed a single piston engine to be installed at the nose of the fuselage rather than high above the fuselage.
SUPERCHARGER - A form of compressor, often turbine-driven, to force more fuel/air mixture into the cylinders of a piston-engine than can be induced by the pistons at ambient atmospheric pressure.
SUPERSONIC - Speed in excess of that of sound.
EGT - exhaust gas temperature (gauge). A device which provides a cockpit readout of the exhaust gas temperature of an aircraft's (piston) engine(s), enabling the pilot to lean the mixture for maximum fuel efficiency.
Conventional aircraft, like piston-engine or jet, are unable to travel to the exosphere. Special aircraft such as the X-15 rocketplane, the Space Shuttle, and SpaceShipOne are designed to fly that high and beyond.
TURBOPROP An aircraft in which the propeller is driven by a jet-style turbine rather than a piston.
When you unpause and fly, your engine lends its lyrical baritone accompaniment to your very heart-beat. If you listen carefully, you can hear voices in its rich pistons and in its throaty, muffled explosions, far-out voices talking to you, saying: ...
GENERAL AVIATION (GA) - All civil aviation except that classified as air carrier or air taxi. The types of aircraft typically used in GA activities vary from multiengine jet aircraft to single engine piston aircraft.
Most modern airliners are equipped with jet engines, which are more powerful and mechanically simpler and more reliable than piston engines. Jet engines first entered commercial service in the late 1950s and were in widespread use by the mid-1960s.

AVGAS: Aviation Gasoline. Usually followed by the octane rating. Used by piston-engined aircraft.
AVTUR: Aviation Turbine fuel (kerosene). Used by turboprops and jet aircraft.
