TsAGI to Develop Propeller Design Principles for Regional Aircraft

28 June 2022

Digital transformation of all national economic sectors is an urgent task set by Russia’s President Vladimir Putin for the current decade. There is a growing demand for enhanced numerical study methods in aircraft industry, in particular, in designing new aircraft.

Rapidly developing local air transport market has raised the issue of creating new regional turboprop aircraft. This requires uniting different software, which determines a propeller engine’s aerodynamic, strength and acoustic performance, into a single complex. Therefore, the Russian Ministry of Industry and Trade announced a tender for creating multidisciplinary design of regional aircraft propeller (tender ID: ‘Propeller—System’). The tender was won by TsAGI (a part of NRC “Zhukovsky Institute”).

Research and development (R&D) will be carried out under the State Programme ‘Scientific and Technological Development of the Russian Federation’. This R&D aims to decrease the terms and increase the quality of propeller designing with enhanced design methods, numerical modeling and multidisciplinary optimization.

‘Today, national aircraft industry really needs the creation of design technologies for advanced aerodynamic configurations of aircraft units. This task becomes much more complicated when we deal with the development of a propeller that would be universal for transport and passenger aircraft and would meet all the requirements on operation, reliability, lifecycle, weight, community noise, onboard noise, thrust performance and power performance. In these conditions, it is important to unite the numerical modeling software into a single complex, forming a system of multidisciplinary design and optimization,’ said Kirill Sypalo, Director General of TsAGI, Corresponding Member of the RAS.

The R&D would be implemented in two stages. The first stage includes an analysis of the industrial institutions’ current technological advance related to aerodynamics, strength, aeroacoustics, and airframe-propulsion integration. At the second stage, TsAGI scientists will use a set of calculation methods to determine propeller characteristics, and will design and manufacture a test model. After bench test, field tests and validation of numerical models, a program will be developed to mock-up the multidisciplinary design and optimization system for regional aircraft propeller. These studies will provide the creation of advanced propeller that would meet the requirements for aerodynamics, strength, aeroacoustics, and propulsion.

The contract is implemented from early May till November 15, 2022. The product will be then integrated into concept design system of new domestic propeller aircraft models.
