For High Cruising Speed: TsAGI Tests Wing Sections with Impeller Distributed Power Plant

The concept may be applied in the future for regional and long-haul aircraft

TsAGI (Zhukovsky Central AeroHydrodynamic Institute) continues to work on the comprehensive scientific and technical project (CSTP) "Integral", related to the appearance of future Russian civil aviation aircraft.

One of the promising elements recently passed successful tests — it is an electric distributed power plant with impeller propulsion units on a promising regional aircraft with energy flow control. It will help the aircraft to expand basing conditions and provide it with a relatively high cruising speed.

Experiments have demonstrated a more than twofold increase in the wing's lift characteristics in takeoff and landing modes. This result was obtained primarily due to the implementation of the supercirculation effect: the operation of the impellers "rebuilds" the flow around the wing. Other factors also played a favorable role: elimination of boundary layer separation from the wing surface and deviation of the thrust vector.

TsAGI conducted studies in a low-speed wind tunnel over a wide range of angles of attack, which confirmed the expected characteristics in computational studies. The scientists also assessed the effectiveness of integrating the power plant with the wing in takeoff and landing modes.

TsAGI notes that the results of these tests will allow the developed approaches to be applied to assess the aerodynamic characteristics of a wing with an impeller distributed power plant when designing a promising aircraft with energy flow control.

Earlier in 2024, TsAGI design engineers said that they created a new type of wing for aircraft with a movable skin. It can be useful for both air aviation and underwater gliders.
