A TsAGI project is among the winners of the Aerospace Innovation Projects Competition within the framework of VUZPROMEXPO-2016 exhibition

30 December 2016

In December the project of the Central AeroHydrodynamic Institute named after professor N.E. Zhukovsky (TsAGI, part of the National Research Center “Institute named after N.E. Zhukovsky”) joined the winners of the Aerospace Innovation Projects Competition. The event was held as part of the annual national exhibition forum VUZPROMEXPO-2016.

Forty-five applications from 12 regions of Russia were filed with the Competition. TsAGI was a nominee to “State-supported projects.” The work, “A dual-mode hydraulic actuator with electrical backup and combined speed control for an elevator of an advanced long-haul ‘more electrical aircraft’” won the second prize.

The goal of the project is to enhance fuel and, therefore, environmental efficiency of a passenger aircraft through implementation of the “more electrical aircraft” concept. A subject of the work is an electric power supply actuator deflecting the pitch control elevator of the aircraft (at take-off, climbing, descent and landing stages). The innovative nature of the solution is combining the hydraulic and electrical power supply in the same device. This allows leaving only two of the three centralized hydraulic systems on board the aircraft, thus reducing the airborne equipment weight. In addition, a special algorithm has been derived to implement two classic control methods, that is throttle control (producing the hydraulic resistance to the liquid flow) and volumetric control (changing the mechanism displacement). The first method is applied in conventional hydraulic actuators, and the second one — in electrohydrostatic actuators. This enhances the standby control quality.

“The Competition and entire exhibition have helped us to establish business contacts with other participants, to broaden outlook and to know better th innovation projects of other science-intensive companies,” Anton Steblinkin, the applicant and one of the authors of the winning project, the Engineer of the TsAGI Flight Dynamics and Aircraft Control Systems Department, remarked. “Our win is certainly another opportunity to promote our design, to make it known by specialists of the Russian aviation industry.”

An organizer of the Aerospace Innovation Projects Competition was TsAGI under the auspices of the Ministry of Education and Science of the Russian Federation and the Fund for Infrastructure and Educational Programs. The event demonstrated the evolution of new developments from research ideas and early innovation stages to a production and process level with target introduction into the production process. Also, the Competition drew attention of industrial and investment companies to the current aircraft engineering and space research.
