Turbomeca Makila
The Turbomeca Makila is a family of turboshaft engines developed for medium to heavy helicopter applications and marine naval use, introduced in the mid-1970s by the French company Turbomeca (now part of Safran). The Makila series powered a range of rotorcraft produced by manufacturers such as Aérospatiale, Westland Helicopters, Sikorsky Aircraft, and Eurocopter and saw service with operators including the French Army, Royal Air Force, Indian Air Force, and Royal Netherlands Air Force.
Development began in the early 1970s within Turbomeca as a response to requirements from Aérospatiale for higher-powered turboshafts to equip the Puma-class and next-generation transport helicopters, alongside competing efforts such as the General Electric T700 and Allison T406. Design work emphasized a single-stage centrifugal compressor coupled with a multi-stage axial compressor and an annular combustor, reflecting contemporary approaches seen in engines like the Rolls-Royce Gem and the Pratt & Whitney Canada PT6. The Makila incorporated advancements in hot-section metallurgy sourced from developments by Peugeot Société Anonyme suppliers and benefited from collaborative testing at facilities linked to ONERA and the Direction générale de l'armement.
Design priorities included power-to-weight ratio, fuel consumption consistent with long-range transport missions exemplified by the NHIndustries NH90 program, and maintainability aligned with support concepts from organizations such as NATO and the European Defence Agency. Certification testing followed protocols of the European Aviation Safety Agency and national authorities including Direction générale de l'aviation civile.
The Makila family evolved through iterative variants optimized for different power classes and environmental envelopes, similar to variant proliferation in families like the Rolls-Royce RTM322 and Honeywell TPE331. Major certified versions included low-rated early series used on machines analogous to the Aérospatiale SA 330 Puma and higher-rated later series intended for heavy transports comparable to the Aérospatiale AS332 Super Puma and Eurocopter AS365 Dauphin derivatives. Specialized maritime-adapted and tropicalized versions addressed corrosion and sand ingestion standards used by operators such as the Brazilian Navy and Indian Navy.
Upgraded subvariants incorporated improvements in turbine blade cooling and erosion-resistant coatings developed in parallel with research at institutions like CNRS and technology partners including Safran Helicopter Engines research centers. Export-specific variants met requirements of procurement agencies including the Ministry of Defence (United Kingdom) and the Ministry of Defence (India).
The Makila series was selected for a range of rotorcraft and maritime platforms. Notable helicopter installations included Aérospatiale SA 330 Puma-family transports, Aérospatiale AS 332 Super Puma, Eurocopter EC225 Super Puma Mk-2, and certain Westland Sea King upgrades, reflecting commonality with programs involving NHIndustries and Eurocopter procurement. Civilian operators included national flag carriers’ offshore support fleets exemplified by Helicopter Transportation Services and CHC Helicopter-style operators, while military users encompassed the French Air Force, Royal Danish Air Force, Royal Canadian Air Force, and export forces such as the Egyptian Air Force.
Beyond aviation, marine auxiliary power and small gas turbine generators for remote bases drew on Makila derivatives in installations analogous to equipment used by Thales Group and DCNS platforms.
Typical specifications varied by subvariant but key parameters paralleled contemporary turboshafts like the General Electric CT7. A representative Makila variant featured approximate take-off power ratings in the 1,800–2,500 shaft horsepower range, a two-stage centrifugal compressor coupled with axial stages, an annular combustion chamber, single-stage high-pressure turbine and multi-stage free-power turbine, and accessory gearbox arrangements compatible with rotorcraft transmission systems developed by Snecma partners and established suppliers such as Hamilton Sundstrand. Materials and cooling systems reflected advances from industrial programs at CEA and component suppliers including ArcelorMittal and proprietary coating firms supplying Safran.
Engines were certified to ambient and icing performance standards promulgated in coordination with authorities such as EASA and were offered with modular line-replaceable units to align with maintenance philosophies used by fleets under contracts with Babcock International and Sikorsky Support Services.
Makila-equipped helicopters entered service in the late 1970s and saw operational deployment in diverse theaters including NATO exercises, United Nations peacekeeping operations, and national emergency responses by agencies such as Sécurité Civile and Ministry of Home Affairs (India). The engine demonstrated reliability in hot-and-high environments similar to missions flown by the Indian Air Force in the Siachen Glacier region and in maritime search-and-rescue operations alongside Coast Guard assets. Over decades, Makila fleets underwent life-extension and mid-life refurbishment programs coordinated with Safran Helicopter Engines overhaul networks and maintenance organizations like Air France Industries.
Logistical support and obsolescence management reflected patterns seen in long-lived engine families such as the Lycoming T53, with aftermarket upgrades provided by partners including MTU Aero Engines in joint ventures.
Production originated at Turbomeca facilities in Aerospace Valley in southwestern France, with supply chain elements spanning Europe including subcontractors in Germany, Italy, and United Kingdom. Component manufacturing employed machining and casting technologies from suppliers comparable to Fives, with quality systems aligned to standards promoted by ISO and procurement practices used by European Aeronautic Defence and Space Company programs. After corporate restructuring, production and support integrated into Safran Helicopter Engines operations, with final assembly, testing, and overhaul performed at specialized sites and test cells coordinated with national test ranges and industrial partners such as Thales and Dassault Aviation.
