The Mil Mi-38 is a medium-weight Russian helicopter made by the manufacturer Kazaner Hubschrauberwerk AG and the design office Mil . In the initial phase of the project part was Eurocopter an investment provided, but this rose from 2,003 before the first flight from the project. The helicopter has since been developed by the design office Mil and Kazan Helicopters, both companies of the Russian Helicopters Group. The Mi-38 is to replace the types Mi-8 and Mi-17 .
history
The preparatory work began in the early 1980s; In 1983 it was decided to develop a completely new helicopter. In 1989 the first model was shown in Paris, and in 1993 the production of two prototypes began in Kazan, the first flight of which was initially planned for 1995, but which was repeatedly postponed due to financial difficulties. As development costs for the program will be 800 million US dollars and dollar US stated as price per machine 10-15 millions. Finally, the first flight took place on December 22, 2003. Approval according to FAR-29 / JAR-29 is sought.

In May 2006, Thales was hired as an avionics supplier. On September 27, 2006 the prototype reached a record altitude of 8,170 m during certification tests with a take-off mass of 11.1 t. The first flight of the second prototype (also with P&W engines) took place on December 2, 2010. The third prototype (called Mi-38-2 ) was again equipped with the Klimow TW7-117W and was supposed to fly for the first time in mid-2010, but could not be delivered in early 2011. The first flight finally took place on November 29, 2013. We are working on versions for patient transport with 16 stretchers, a VIP helicopter for twelve people, a sea variant and a variant for search and rescue services. The fourth prototype was included in the test program on November 12, 2014.

The delivery of the first series machine was originally supposed to take place in 2008, but has been postponed several times. The Mi-38 received type certification from the Russian Aviation Authority Rosaviazija at the end of 2015 . The first series helicopter was presented at MAKS 2019, the first delivery to Gazprombank Leasing took place in February 2020 . Two helicopters of the variant Mi-38T with a rescue hoist and a loading dock for the transport of 40 soldiers or up to 12 stretchers are in the Russian armed forces tested.
construction
The cabin, largely made of composite material , has been enlarged compared to its predecessor. The six-blade main rotor made of composite material with elastomeric joints was taken over from the Mi-28N , the tail rotor is formed by two independent two-blade rotors in an X arrangement. Initially two shaft turbines Pratt & Whitney Canada PW127 and later two Klimow TW7-117W , each equipped with FADEC , served as drive . In addition, an EFIS with five color displays and a fly-by-wire system with mechanical backup are used. The nose gear is not retractable.
