The specialists of Central Aerohydrodynamic Institute (TsAGI) named after N.E. Zhukovsky are preparing for testing of the large-scale model of short- and medium-haul MS-21 aircraft with a local strain gauging, TsAGI’s press-service reported.
The tests scheduled for late March 2014 will be carried out in T-104 wind tunnel owned by TsAGI. The research work is being carried out in accordance with the contract between TsAGI and Irkut Corporation. «The model of the advanced airliner will be tested in three positions (in terms of height) with different angles of attack above a plate simulating the runway», - the press-service noted.
A large number of strain-gauge weighers will be used during testing for the first time ever (17 ones). «This equipment will allow us to measure the loads and torques more precisely (this refers to loads and torques applied to the aircraft controls and components of high lift devices due to the impact of airflow during takeoff, landing and taxiing). The scale of the model is 1:8; it allows obtaining the data close to the parameters of the real aircraft», - the press-service added.
