Bölkow Bo 108

The Bölkow Bo 108 is a German multi-purpose helicopter developed by Messerschmitt-Bölkow-Blohm in 1988.

The design of the helicopter model Bölkow Bo 108 began by German engineers and designers in the early 80s of the last century, while, as preliminary developments, aircraft manufacturers used previously created aircraft, including models such as Bölkow Bo 105, Bölkow Bo 106 and others.

Even though some elements of the Bölkow Bo 108 helicopter are similar to previous models, the aircraft is almost unique in-flight performance, which made it very popular, both in the military sphere and in the civilian one.

The first flight tests of the Bölkow Bo 108 helicopter were carried out in 1988, however, the aircraft could not complete them, and therefore, already in 1991, the second prototype of this aircraft was presented, which turned out to be both more reliable and more advanced in terms of its operational capabilities.

Due to its special aerodynamic shape, the Bölkow Bo 108 helicopter is a rather maneuverable aircraft, which has successfully proved itself in its subsequent application, however, already under the release of the aircraft manufacturer Eurocopter, better known as the Eurocopter EC135 model, although up to now there are original versions produced by the German company “Messerschmitt-Bölkow-Blohm”.

The helicopter cabin allows you to place on board an aircraft up to 7 people, including 1-2 crew members and five passengers, which is very acceptable both in the civilian sphere of aviation and in the military sphere, where the helicopter was also subsequently actively operated. Among other things, due to the presence of a rather large free space, the Bölkow Bo 108 helicopter can also be used to transport quite large loads on its board, the only limitation of which is the maximum take-off weight of the aircraft, which is 2500 kilograms.

The power plant of the aircraft model Bölkow Bo 108 consists of two gas turbine engines of the brand Allison 250-C20R-3, or the brand Turbomeca TM-319 Arrius 1B, having a thrust of 455 and 490 hp each, respectively, which provides the aircraft with an appropriate cruising flight speed of 270 and 285 km \ h. The maximum distance over which the aircraft model Bölkow Bo 108 can fly is 800 kilometers.

To date, the production of Bölkow Bo 108 helicopters is carried out exclusively by Airbus Helicopters under the name Airbus Helicopters H135.
