There are various approaches to compress air, and throughout the years a wide range of sorts of compressors have been imagined to do as such. Their brilliant outlines permit a strategy to pressurize atmospheric air and there are three basic methods for doing as such. The three best air compressor are the reciprocating air compressor, centrifugal air compressor, and rotary screw compressor.

The Rolls-Royce Gnome is a British turboshaft engine originally developed by the de Havilland Engine Company as a licence-built General Electric T58, an American mid-1950's design. The Gnome came to Rolls-Royce after their takeover of Bristol Siddeley in 1968, Bristol having absorbed de Havilland Engines Limited in 1961. A licence to manufacture the T58 was purchased in 1958, they began bench testing in 1955 and by 1958 had already been used in helicopters and de Havilland were able to test their first engines in a Westland Whirlwind and Wasp helicopters in August 1959 and March 1960 respectively. A free-turbine turboshaft, it was used in helicopters such as the Westland Sea King and Westland Whirlwind. The design was sub-licensed to Alfa-Romeo. There were two series produced: the ''H'' turboshaft for helicopter use, and the ''P'' turboprop for fixed-wing aircraft.
A two-stage turbine drives the 10 stage all-axial compressor, whilst a single-stage free power turbine drives the load. The combustor is annular. The Gnome differed from the T-58 in having a British developed fuel control system (Lucas). Because an all-axial design is employed, the final stage compressor rotor blades are amongst the smallest ever manufactured. Normally, a small engine such as this would feature an axial/centrifugal or even a double centrifugal compressor. The engine was the first developed with a full authority analogue computer, de Havilland Propellers' own, as part of the fuel control system, specifically to anticipate helicopter power demand from pilot control inputs and to limit fuel flow during acceleration to prevent engine surge from occurring. The system developed relieved the helicopter pilot of the need to control rotor speed directly, it delivered constant rotor speed under varying rotor load, and in this way was the analogue forerunner of all subsequent full authority digital engine control (FADEC) systems worldwide.

An old air compressor that was used when work on the memorial started. In the orientation film, Ziolkowski told a story about starting the compressor, climbing up the mountain, hearing it go "kaput kaput kaput" and die, and climbing back down the mountain to restart it.
The air conditioner compressor and all of the right side engine brackets were cleaned and inspected then installed.
