Russia is developing a new generation supersonic passenger aircraft (SPS). Leading Russian scientists and engineers, united in a consortium of the world-class Supersonic Research Center, are working on innovative solutions for a promising machine. About how work is being done on aircraft, Izvestia was told at the Moscow Aviation Institute (MAI).
The Institute carries out work on optimizing the aerodynamic appearance of an aircraft, modeling the impact of a sonic boom, the behavior of the airframe structure, harmful emissions, acoustic loads, and others.
“In addition to being highly aerodynamic, a supersonic aircraft must provide low noise levels during takeoff and landing and low sonic boom during supersonic cruise flight. Our tasks include optimizing the layout, that is, the appearance of the ATP, in terms of these criteria, ”said Andrey Kataev, a participant in the work, head of laboratory No. 1 of NIO-101 MAI.
MAI specialists have created their own calculation methodology and a software package that allows solving these problems. Several variants of the shape of the future aircraft in 3D have already been developed.
One of the innovative solutions of the development team is the use of probionic structures in the new aircraft. Structural-power schemes of aircraft units are proposed to be built, for example, according to the principle of an animal skeleton, where different parts are adapted to different loads. Two versions of the SPS wing probionic structures have already been developed. They are investigated in terms of mass and strength.
The main purpose of using proionic structures is to reduce the weight of aircraft units and increase their degree of integrity.
To date, the MAI has developed a methodology for performing calculations and made a layout of the software package: the user in three-dimensional space can designate the airport area with the terrain, the permissible radius of pollution, the wind rose. Sources of pollution are also specified: aircraft taking off and landing at this airport at a certain time, their types of engines and fuel.
Using the program, you can calculate the spread of pollution from given sources.
Another layer of work is associated with the SPS cabin. Direct vision of the space ahead of the aircraft is not provided, and the pilot will receive all information about the flight through a set of displays combined into a single information field. As part of this direction, the MAI is developing a special predictive display that improves piloting safety. The technology makes it possible to predict the trajectory of an aircraft and visualize it as a three-dimensional corridor with a set of marks that will help the pilot to correct the course.
The MAI specialists also proposed the idea of an active aircraft control lever. The output signal of such a lever is proportional to the force applied to it. As preliminary studies have shown, when using such a device, the piloting error is reduced by 2.3 times.
In addition, research participants are working on optimizing the ATP trajectory in terms of noise reduction and avoiding collisions with other aircraft, developing an intelligent pilot support system, a complex for monitoring all aircraft systems, a reconfiguration system, and cybersecurity.
On January 31, MAI told Izvestia that the LMS-901 Baikal light multi-purpose aircraft, the airframe assembly of which was carried out at MAI, can be called an improved successor to the An-2 aircraft.
It is noted that Baikal will be able to lift 2 tons of payload, develop a cruising speed of 300 km/h and cover distances of up to 1.5 thousand km, taking off from unpaved strips 250 m long.
On January 30, the head of the Ministry of Industry and Trade of the Russian Federation, Denis Manturov, announced that Baikal had made its first flight. The plane took off from the Ekaterinburg airfield in the city of Aramil, Sverdlovsk region. The flight took place at an altitude of 500 m and lasted about 25 minutes. As part of the flight mission, test pilot 1st class Valentin Lavrentiev performed maneuvers to test the stability and controllability of the aircraft in the air. According to the pilot, during the flight mission, the aircraft systems worked in the normal mode.
