A series of turbine wheels are turned by a gas turbine engine found in turbine helicopters. The gearbox then reduces the engine’s output to the ideal rotor RPM. It is quite close to the speed of sound at sea level, which is 340 metres per second, when a conventional turbine helicopter is flying forward at 150 knots with its advancing blade tip moving at about 295 metres per second.
For every 100,000 flying hours, turbine helicopters had an accident rate of 6.69, compared to 3.59 for the S-76 globally. According to 100,000 flight hours, there were 9.11 accidents in general aviation involving both fixed- and rotary-wing aircraft.
The Global Turbine helicopter market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Enstrom announced that the 480B turbine helicopter has completed its first flight. The 480B is the 1317th helicopter Enstrom has built and the 255th in its 480 series, the company stated, emphasising that the recently flown aircraft was not a “left-over airframe” from the pre-bankruptcy production line but was instead constructed using components that were newly made and put together on-site.
There are no problems. The flight test procedures could be finished entirely and promptly. In building this helicopter, the team did a fantastic job.
The first helicopter to use a gas turbine-driven gearbox to fly was the Kaman K-225. Turbines provided significant benefits for helicopters, including lighter weight, more reliability, simpler maintenance, and higher power-to-weight ratios that allowed for greater usable weights, higher safety standards, and cheaper operating costs. The commercial K-225 model was produced by Kaman in 1949, principally as a crop-duster.
The intermeshing rotor system and the unique blade mounted servo-flap control system were ordered by the Navy, and two were sent out to assess their benefits.
Kaman installed a Boeing 502-2 gas turbine in lieu of the reciprocating engine that had previously propelled this K-225 in order to show the Navy the potential of jet-powered helicopters. Kaman’s successful HOK series of military helicopters, which included a cabin in place of a cockpit, was based on the K-225 as a prototype.
