Aerospace Technic and Technology

In the "Antonov" Company, a unique medium-sized tactical military transport aircraft An-12 and An-70 have been created. Based on the Аn-12 basic version, several modifications have been developed, which operate in many countries around the world.

To replace this aircraft has been created the An-70 with a higher capacity and hourly capacity, which on some key parameters outperforms the competition-analogs: American C-130J-30, West-European A400M, and Japanese C-2.

However, the range with the maximum capacity is worse for Аn-77 compared to the A400M, but cruising speed and combat readiness – for C-2.

For the most complete implementation of tactical tasks:

– transportation of personnel, equipment, goods, and means of procurement;

– delivery of military units, equipment, and cargo in the interests of peacekeeping or counter-terrorism operations;

– transportation of troops, arms, military equipment and material resources of strategic direction;

– delivery of units and formations of the airborne forces and ground forces in the areas of military purpose;

– provision of the relocation of aviation units and formations, and provision of superiority at range with maximum load, at cruising speed and combat readiness the team of the “Antonov” Company created the An-188 – the medium-sized tactical aircraft with short takeoff and landing, which provides execution of a series of tasks, not available even for C-2.

At the initial stage of designing this modification scientific principles the "Design techniques of modifications of the MTA taking into account the profound changes in the wing and the power plant" were used. The most important modification change in An-188 is the replacement of the D-27 turboprop engine for СFM LЕАР-1A turbofan engine, which increased the capacity and combat readiness of modification.

Another important modification change was the use of discrete geometric twist of the wing local chord, bringing its shape in plan view to elliptical one and has brought a reduction in induced drag for a given lift force. This solution provided an increase in the range of up to 3200 km.

Such profound modification changes in the power plant and the geometry of the wing have contributed to the complete superiority of the An-188 in the class of operational-tactical MTA.

In combination with An-132D and An-178 modification, the An-188 can be considered as a unified system of support for the troops with military transport planes.
