The multi-purpose fifth-generation Su-57 fighter "caused an unimaginable stir" at the Airshow China air show in Zhuhai. This proves the interest in Russian aircraft construction, said Sergei Bogdan, chief pilot of the Sukhoi Design Bureau.
Russian aviation is respected. The excitement around the Su-57 aircraft confirms interest in Russia itself and its aircraft construction.
On the complexities of aerobatics on the Su-57
According to Bogdan, another element was added to the program — an ascending spin.
Previously, we did a descending spin. We made a long bell: when the plane moves forward at almost zero speed, but from the side it looks like it is standing still. This is due to engine thrust and the control system.
What factors influence piloting?
The chief pilot of the Sukhoi Design Bureau admitted that the weather is a critical factor for demonstration piloting. The pilot needs to build the program in such a way that the weather does not affect it.
An hour before the flight, the weather may be one, but it will change before departure. This is perhaps the most difficult moment at air shows. No improvisations are allowed — everything must be planned and worked out.
Spin in aviation
Spin is one of the most difficult flight modes. Piloting an aircraft in this mode differs from normal flight operations.
A spin is called the involuntary movement of an aircraft along a steep spiral trajectory of small radius in autorotation mode. In an ascending spin, the aircraft moves along an ascending trajectory, that is, it performs a dynamic climb in a spiral.
Soviet pilot Konstantin Artseulov first performed a spin on the Nieuport-21 aircraft in 1916. He rose above the Kacha airfield to a height of 1500 m and sent the plane into a spin. Professor Sergei Vedrov and test pilot Yuri Stankevich studied the spin in 1935.
In modern aviation, pilots deliberately put the aircraft into a spin during training flights, when performing individual aerobatics, and during special flight tests. The spin is also used as a tactical maneuver to escape from anti-aircraft artillery fire.
