Turbine sound Studios is proud to present the Mighty Sikorsky S-61 helicopter soundpack.

As one of the worlds most versatile, and popular, helicopters, in use by many forces throughout many continents this is a soundpack we have truly worked hard to bring to you in vivid clarity.

Designed in harmony with the Microsoft Flight Simulator Sound Engine we feel that this could possibly be the best helicopter soundpack available as of this moment.

Accurately recorded "live" by TSS thanks to the Danish military we guarantee nobody has put as much work into a helicopter soundpack as this ever before (and we mean that!)

You can hear the swing of the massive blades as the T58 engines power up and down. The hum of the avionics as recorded from inside the cabin, as if you were there!

 

See the preview below (compressed quality) to see for yourself:

The General Electric T58 was a US 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. It was the first turbine engine to power a helicopter in the United Sates, and the first turbine engine to gain FAA certification for civil helicopter use. The engine was licence-built and further developed by de Havilland in the UK as the Gnome, and also manufactured by Alfa Romeo and IHI.

Development commenced with a 1953 US Navy requirement for a helicopter turboshaft to weigh under 400 lb (180 kg) while delivering 800 hp (600 kW). The engine that General Electric eventually built weighed only 250 lb (110 kg) and delivered 1,050 hp (780 kW) and was soon ordered into production. First flight was on a modified Sikorsky HSS-1 in 1957 and civil certification for the CT58 variant was obtained two years later.

The main production version of the engine was the T58-GE-10, developing 1,400 hp (1044 kW), as depicted in this Soundpack
