IPTN N-250 - a multi-purpose turboprop civilian aircraft, developed by Indonesian aircraft manufacturer «Indonesian Aircraft» in 1995 year.

Despite the fairly large demand in turboprop aircraft, after successful testing of the aircraft in 1995, the project further development of the airliner was temporarily shelved due to lack of sufficient number of investments, however, in 2014, the Indonesian aircraft manufacturers have announced the beginning of serial production of the aircraft with 2018 years.

The IPTN N-250 aircraft has a multi-purpose purpose, in particular, it is suitable both for passenger transportation on regional air routes, and for the transport of certain cargoes with a total mass of up to 3,8 tons. The initial tests of the IPTN N-250 aircraft were quite successful in 1995, however, the management of the Indonesian aircraft construction company came to the conclusion that the aircraft would not be able to meet all customer requirements, which resulted in the appearance of an expanded version of this aircraft a few months earlier Processing, however, due to lack of funds, the project was completely frozen.

Depending on the aircraft, on board IPTN N-250 can accommodate up to 50 68 passengers, largely superior to most turbo-prop aircraft in civil aviation. In addition, it is assumed that with the start of serial production of passenger aircraft IPTN N-250 increase to 70-75 people, which in turn will allow the already compete even jet airliners.

The power plant of the aircraft IPTN N-250 is represented by two turboprop aircraft engines of the Allison AE2100C model, each of which is capable of developing traction in 3270 hp, which is very high. The maximum speed of the flight of this aircraft is 690 km / h, which in turn is slightly less than for jet aircraft equipped with turbofan engines, but significantly larger than the existing turboprop aircraft. One of the most striking shortcomings of this aircraft is the short distance, which is only 1480 kilometers, but if the project is resumed, it is expected that this figure will be increased to 1700-2000 kilometers.

According to 2015 year, model aircraft IPTN N-250 was designed in two different versions:

  • IPTN N-250 - Main production version of the prototype;
  • IPTN N-250-100 - An enhanced version of the plane, with more than The length of the fuselage, and the increase in the passenger capacity, the maximum take-off weight, and others.
