Military aviation
In aerodefence applications, Avio plays two distinct roles. It designs and manufactures high-tech products like low pressure turbines, power transmissions, accessory gearboxes, afterburner stages and auxiliary power units. It is also responsible for component assembly, testing, qualification, delivery and after sales services for the Italian armed forces.
A recognised leader in component design and manufacture, Avio is a participating partner in many European defence aerospace programmes as a design responsible company. These responsibilities comprise turbofans (SPEY for AMX; RB199 for Tornado; EJ200 for Typhoon), turboshafts (T700 in risk revenue sharing with General Electric for the EH101 and NH90 military helicopters and the CargoLifter 160 dirigible), and auxiliary power units (150 Argo for AMX; 36-170 built with Honeywell and Cesa for the Eurofighter).
With the innovative EJ200 engine being built by the Eurojet Consortium for installation on the new AF2000 "Typhoon", Avio is responsible for several of the engine’s key components, including the gearbox, low pressure turbine and afterburner.
But Avio’s efforts in the development of the Typhoon go beyond the aircraft engine. In fact, Avio also heads the DFZI Consortium, which will build the AMAD gearbox, and is a member of the Consortium which will produce the aircraft’s Auxiliary Power Unit (APU).
Avio also produces accessory gearboxes for the Pratt & Whitney F119 engine which will power the U.S. Airforce’s fighter F22 Raptor.
In addition to its role as a design responsible company for the F124 engine modules, Avio is also responsible for the assembly and test activities for most of the F124 engines that will power the Aermacchi M346 trainer.
Complete engine
Avio participation in several military programs allowed the development of a significant capability in the management and performance of overall engine assembly and test.

Accessory gearbox engine mounted
The accessory gearbox is a key module in modern jet and turbofan engines. Its function is to transfer mechanical power from the engine shaft, through a properly designed gear train, to different outlet shafts, rotating at selected speeds, on which accessories and components like starters, hydraulic pump, etc. are mounted.
Low Pressure Turbine
The low pressure turbine is one of the main engine modules. It drives the low pressure compressor or the fan by taking energy from the hot gas coming from the engine combustion chamber and high pressure turbine.
Combustion chambers, re-heat, exhaust system
Avio began its involvement in the analysis and design of combustion systems in various military and space propulsion programs during the '80s. The development of the EJ200 re-heat system helped improve the design and testing capability and manufacturing technologies.
Auxiliary Power Unit
The Auxiliary Power Unit mainly provides electrical power to drive aircraft accessories and compressed air to start the engine.
Components and structures
Besides the development and production of complete engine modules, Avio is also involved in the design, test, manufacturing and repair of complex and technologically valuable components on a wide variety of jet engines and turbofan. Among the most challenging parts are: turbine blades and vanes, turbine and compressor disks and shafts, rotating seals, bearing and shroud supports, big frames, casings and other structural parts.
