Hartzell introduced a turboprop propeller in 1961 and, in 1975, certified a 5-bladed propeller for the Short 330. [9] [12] In 1978, the company produced a composite aramid fiber propeller for the CASA 212. [13] In 1989, Hartzell produced sixteen-foot propellers for the Boeing Condor, another record-breaking aircraft. [11]
The 715 shp TPE331-6 used in the Beech King Air B100 have a 400-hr. fuel nozzle cleaning interval, 1,800-hr. hot section inspection interval and a 5,400-hr. time between overhaul; approval is possible for 3,000-hr. HSIs and 6,000-hr. overhauls and engine reserves are cheaper than for the PT6A.
Robert Norris Hartzell (born June 3, 1896 in Ohio, died December 11, 1968) was an American entrepreneur who started Hartzell Propeller in 1917, a company that produces aircraft propellers. [ 1 ] [ 2 ]

The TBM 900 saw the adoption of a new five-bladed propeller, specially optimised by Hartzell based upon airflow simulations conducted of the TBM's forward section. According to SOCATA, Hartzell's selection over a similar advanced counterpart from MT-Propeller was made due to the former raising the cruise speed by around 3 to 5 kn (5.5 to 9 km/h).
A constant-speed propeller is a variable-pitch propeller that automatically changes its blade pitch in order to maintain a chosen rotational speed, regardless of the operational conditions of the aircraft. This is achieved by use of a constant-speed unit (CSU) or propeller governor, which automatically changes the propeller's blade pitch.
