TsAGI to present models of future aircraft at MAKS-2013

26 August 2013


Zhukovsky Central Aero-Hydrodynamic Institute will take part in the International Aviation and Space Salon MAKS-2013 and will act as organizer of a joint exposition by seven Russian aviation science centers. TsAGI, CIAM, VIAM, GosNIIAS, LII, SibNIA and FSE “GkNIPAS” who will present their scientific and technological achievements in an exhibition space of over 400 square meters, located in Pavilion № D2.

In the central part of the joint exposition there will be models of future aircraft, in the development of which all the participants in the stand took part.

The public will be able to see models of aviation technology tested in TsAGI wind tunnels, and models being presented for the first time include:

A model of a light multi-purpose aircraft (LMA).

The LMA demonstrator model was designed, produced and tested at TsAGI. The project is being implemented to support creation and mass production of a range of aircraft, with a capacity of 9, 13 and 19 seats, capable of operating on low-cost regional routes with short dirt runways and other difficult conditions. In the future, the demonstrator aircraft will make it possible to develop innovative solutions such as: improving aerodynamic design with a high-lift wing, which will allow for combining efficient cruising with short take-off and landing, the use of two motors with synchronized transmission, a pressurized cabin, which improves comfort, range and flight speed; an all-composite airframe, providing weight efficiency and low labor intensity, and an automated control system, providing increased safety. Having drawn a “portrait” of this future aircraft, TsAGI is actively pursuing its research. The real demonstrator aircraft is expected to appear in three years.

Model of a flying-wing design long-distance aircraft.

The model airplane was designed, produced and tested in TsAGI. The “flying wing” is one of the most promising configurations for future aircraft. The main advantage of the “flying wing” is its ability to achieve high aerodynamic efficiency at a cruising flight of over 23, and significantly reduce ground noise by shielding the motor elements of the airframe. TsAGI has studied this design for a number of years, and has now dispelled the misconception that this aircraft can only be for super-large passenger volumes of up to 1,000 seats, demand for which is very limited. The model presented is not just a model of a long-haul aircraft in the form of a “flying wing”, it is the model of an airplane with 180-200 seats, which makes this project competitive in terms of the global market. The “flying wing” will be able to achieve similar speeds as current long-haul aircraft, but it will be 25-30% cheaper. Some of the seats in these aircraft are located in the wing. Various options are being considered for the number and location of engines and the geometry of the tail.

Model of sub-sonic executive aircraft.

The model airplane was designed, produced and tested in TsAGI. This future small executive jet with an increased comfort level has a unique patented layout — a drop-shaped fuselage and straight wing. And contrary to the prevailing belief in the aerodynamic community, the new aircraft will be able to reach speeds up to M = 0.77 for maximum-range flights and up to M = 0.8 at the so-called maximum cruising speed. The interior height of the aircraft, designed for 3-9 passengers, will be one of the biggest in the world (1.9 m). The maximum take-off weight of the aircraft is about 6000 kg, and its range is 3200 km with 6 passengers and 4,200 km with three passengers. TsAGI presented a version that has certain advantages. The large size of the cockpit ensures a high level of comfort, and the small size of the aircraft itself will make the transportation of a limited number of passengers more economical.

“The main criterion when choosing the models was the topicality of the specific scientific work and its contemporary relevance to the domestic industry,” TsAGI Executive Director Sergey Chernyshev said. “So, the work on creating the LMS was a response to a request from the country’s leaders to work on aircraft for local airlines. Business aviation is not currently very well developed in Russia and the original layout of the subsonic business jet is our contribution to this segment. Another non-traditional aircraft — the ‘flying wing,’ — is a long term project. This is the next generation of aircraft, with which existing aircraft will not be able to compete.”

Visitors to the TsAGI stand will also be able to see:

Concept for demonstrator model of plane for local airlines.

The model has an original patented layout for a propulsion system for an aircraft for local airlines, developed by TsAGI specialists. The location of the two motors in the tail of the plane, spinning one propeller located on the T-tail, makes it possible to, among other things, improve environmental safety, the reliability of the propulsion system, and to raise the comfort level of passengers (noise reduction on the ground and in the cabin). Its high aerodynamic performance during takeoff and landing are due to its relatively low landing speed. This improves safety when operating from aerodromes where there is no automated landing. The passenger capacity of the local aircraft is 15-19 seats. The cargo version of the aircraft can carry up to 2000 kg.

Idealised model of agile aircraft with strain gauge control mechanisms.

The model and measurement instruments were designed and manufactured by TSAGI for Sukhoi. These developments are designed to study the aerodynamic loads and moments acting on the controls and to determine their effectiveness in TsAGI wind tunnels in high Mach numbers ranges, at high angles of attack and slip. This model shows TsAGI’s capabilities for determining aerodynamic design and forming new ideas and solutions for modern agile aircraft.

Complex model of the Angara-A5 space rocket.

This model was designed, produced and fitted with instruments for measuring heat flow and static pressure at TsAGI on behalf of the Khrunichev State Research and Production Space Center. The model will be used for experimental studies in the TsAGI large hypersonic wind tunnel for the simultaneous determination of static pressure and heat flow in zones of interference on the central and side blocks of the rocket. The Angara-A5 is an example of very close cooperation with the developers, and demonstrates the broad research capabilities of the Institute, not only for the development of aviation technology, but also of launch vehicles.
