TsAGI holds visualization tests of heavy transport aircraft

20 December 2018

Specialists of the Zhukovsky Central AeroHydrodynamic Institute (TsAGI, a member of the National Research Center “Zhukovsky Institute”) completed the next stage testing of the heavy transport aircraft, the integrated circuit model. Scientists studied the physical phenomenon of the airfoil flow. The experiments were conducted in TsAGI low-speed wind tunnel.

The tufting survey provided the possibility to see the directions of spot speeds of the studied model and identify the point of separating flow. It is indicative of the developed aerodynamic layout’s perfection.

The experiments helped to determine the reasons for reducing the aerodynamic characteristics at certain angles of attack, as well as helped to highlight a number of interesting features of the flow phenomena of such a layout. So, the Institute’s specialists found that the center wing maintained attached flow at the angles of attack, significantly exceeding its incidence capability.

Using the results of visualization and weight tests, scientists will be able to find solutions to improve the aerodynamic performance of the aircraft by testing the general and local aerodynamics.

The advanced heavy transport aircraft of integrating circuit is designed for intercontinental transportation (up to 6 thousand km) of a large volume of cargo (up to 500 tons), including standard containers. They will be placed in a wing cell and loaded via flap doors in the front sections of the aircraft’s central part.

The aircraft is planned to be used on existing runways. Such an aircraft flies primarily at an altitude of 3-12 mabove water, ice or land. These surfaces create a screen effect, which increases the aerodynamic quality. It results in an increase in range and fuel (natural compressed gas) economy.

Such an aircraft could be used for heavy transport, both domestic and international.
