The Artouste II family, mainly used in the Aérospatiale Alouette II helicopter, had a one-stage centrifugal compressor and a two-stage turbine, with gearbox-limited power of 300 kW (400 hp). The Artouste III family, mainly used in Aérospatiale's Alouette III and Lama helicopters, had a two-stage axial-centrifugal compressor and a three-stage ...
The Rover 1S60 is a gas turbine manufactured by Rover Company and the first industrial type for production [1] Many were used for aircraft such as Auxiliary power units for groundcrew and Auxiliary Airborne Power Plants on aircraft. [2] Other uses of the Rover 1S60 was used as fire pumps and Auxiliary generators on hovercraft.

TRS 18-076 Intended for the Meteor-Mirach 100. Includes an engine driven alternator and fuel and oil lubrication pumps. Dry weight as 18-046.
Safran Helicopter Engines, previously known as Turbomeca, is a French manufacturer of low- and medium-power gas turbine turboshaft engines for helicopters. The company also produces gas turbine engines for aircraft and missiles, as well as turbines for land, industrial and marine applications.
It can be seen from the tables that the pass rate (score of 3 or higher) of AP Calculus BC is higher than AP Calculus AB. It can also be noted that about 1/3 as many take the BC exam as take the AB exam. A possible explanation for the higher scores on BC is that students who take AP Calculus BC are more prepared and advanced in math.
Wright R-3350 Duplex-Cyclone Turbo-Compound radial engine.. The first aircraft engine to be tested with a power-recovery turbine was the Rolls-Royce Crecy.This was used primarily to drive a geared centrifugal supercharger, although it was also coupled to the crankshaft and gave an extra 15 to 35 percent fuel economy.
In the late 1980s there was a need for a similar but more powerful engine for the next generation of the cruise missiles and drones. Microturbo addressed this by developing the "Quadri-axial" class of TRI 60 engines. They increased the air flow through the engine and added a fourth compressor stage (hence the name). [1]
The General Electric T58 is an American turboshaft engine developed for helicopter use. First run in 1955, it remained in production until 1984, by which time some 6,300 units had been built. On July 1, 1959, it became the first turbine engine to gain FAA certification for civil helicopter use.
