TsAGI commissions a seasonal air cooler tube
28 December 2016
Specialists of the Central AeroHydrodynamic Institute named after professor N.E. Zhukovsky (TsAGI, part of the National Research Center „Institute named after N.E. Zhukovsky”) have designed and commissioned a new pilot unit — a seasonal air cooler tube. The work was performed in cooperation with CIAM and subcontractor organizations.
The unit is intended for research of simulated icing processes on lifting surfaces and bearing members of an aircraft, icing influence on aerodynamic characteristics of an aircraft, icing control methods, characteristics of instruments and sensors in icing conditions, and anti-icing system efficiency. The information obtained by the specialists from air cooler tube tests will be used in solving tasks of flight safety and aircraft certification shortening.
By now the Institute employees have verified operability of the main process and measurement systems of the unit, carried out the trial run, and managed the simulated icing of a reference lattice.
Next year the TsAGI specialists will test the procedure of seasonal air cooler tube pre-testing and testing.
An air flow in the tube is forced with a fan driven from a 1 MW AC asynchronous motor. The size of a closed test section is 1 × 1 × 3 m, maximum flow speed is 150 m/s, operating temperature range is < 0°С.
