Abstract

The paper presents exemplary results of numerical simulations focused on numerical simulations and reconstructions of aircraft flights and accidents.

These works were carried out for both fixed-wing and rotary-wing aircraft during last seven years at the Institute of Aviation Technology.

These investigations were mainly theoretical but some of them were verified on the basis of data recorded during flight tests. All investigations were founded on the classic model of an aircraft, which was treated as a rigid body. Spatial manoeuvres of aircraft were modelled by making use of inverse simulations.

This method allows to determine control necessary to perform an assumed manoeuvre. Some main results are presented for both normal flight and aircraft crash.
