TsAGI participates in the International Electric & Hybrid Aerospace Technology Symposium 2017

29 November 2017

In November 2017 the Zhukovsky Central AeroHydrodynamic Institute (TsAGI, a member of the National Research Center “Zhukovsky Institute”) participated in the International Conference “Electric & Hybrid Aerospace Technology Symposium 2017,” dedicated to the development of hybrid electric aircraft. The event took place in Cologne (Germany).

The key issues of the Symposium were the questions how to make aviation environmentally friendly, cost effective, reliable, personal (we are talking about a single-seat drone aircraft) due to the use of electric and hybrid power systems, and their integration with airframes. Participants discussed all aspects of aerospace activity, from general aviation and drones to regional and mainline aircraft.

TsAGI scientists presented the report on “Comparative Evaluation of the Efficiency of a Regional STOL Aircraft with Distributed Electric Propulsion System (DEPS).” Parametric studies were conducted to compare the characteristics of a 40-seat regional aircraft with two turboprop engines and 10 additional electric engines with propellers, blowing on the wing at take-off and landing to increase the lift. In cruise flight, the propellers of DEPS were retracted into the wing without creating additional drag. DEPS engines were powered by generators installed on gas-turbine, turboprop or turbojet, or from an electric battery.

“The use of DEPS, additional generators for its power supply and electrical wiring leads to an increase in operational weight,” said Semyon Mikhalyov, Research Officer in Department of System Research and Conceptual Design of Aerospace Technology of TsAGI. “At the same time, propeller effects allow us to increase the lift and reduce the wing area, which leads to improved fuel efficiency.” Also, TsAGI specialists had consultations with representatives of foreign organizations as part of the expansion of international cooperation and the development of this research.

The Conference is held annually and is one of the most important events for professionals in the field of aerospace engineering. The event allows participants to discuss and analyze the development of hybrid electric aircraft and even the possibility of pure electric-only commercial platforms.
