Powered by a 300-horsepower Continental IO-550-B engine and a three-blade constant-speed propeller
, the Bonanza G36 has a maximum cruise speed of 176 knots, a maximum range of more than 860 nautical miles, a 1,038-pound maximum payload and a 18,500-foot service ceiling.
The diameter and blade size of a constant-speed propeller is often larger (than a fixed-pitch), due to the variability of blade angles.
The constant-speed propeller, meanwhile, is designed to maintain a specific rpm no matter the airplane's airspeed or the engine's power setting.
It had retractable landing gear, a constant-speed propeller
, and hydraulic flaps and brakes.
Unpressurised, and powered by a Textron-Lycoming 180hp piston engine driving a Hoffman three-bladed, constant-speed propeller
, the Tutor can cruise at 130kts at sea level and climb to 5,000ft in seven minutes.
On multi-engine aircraft, this Hydromatic constant-speed propeller
had the ability to "feather," stopping the propeller's rotation, to keep the propeller from windmilling after an engine failure.
For a constant-speed propeller
, an overhaul consists of an initial visual inspection; disassembly; cleaning of all components that are not to be replaced; inspect, measure, conduct nondestructive testing, which may include dye penetrant, eddy current and/or magniflux; rework/refinish components to be reused; cadmium plate components with a corrosion risk; finish/paint components; replace hub studs, miscellaneous hardware, seals and gaskets; reassemble; balance; and bench test--set pitch angles and assure the blades match at all reference stations.
keep eta at this efficiency level at pretty much all cruise speeds.
Hartzell Propeller has signed an agreement with Hawker Beechcraft to supply constant-speed propellers
for the airframer's new piston and turboprop aircraft, including the Beechcraft G36 Bonanza, G58 Baron and the King Air C90GTX, B200GT and 350i.
With the formation of NACA, groundbreaking aeronautical research led to the growth in the 1920s and 1930s of technical improvements such as constant-speed propellers
and standardized airfoil sections.
were a great thing to have, straightening us out before we hit a dry spot.
For other manufacturers, most of which concentrate on constant-speed propellers
, 72 months is the upper calendar limit and 2400 hours the maximum time-in-service before a prop mounted on a piston engine needs to see a shop.
