The PD-8 engine control system for the SJ-100 aircraft, developed by ODK-Star, has successfully passed tests at extremely high temperatures. The SAU-8 hydro-mechanical units withstood flame tests and remained operational at a temperature of 1100 degrees Celsius. This was reported in the press-service of UEC.
The first fire resistance tests were held at the Central Institute of Aviation Engine Building named after P.I. Baranov (CIAM). The main units of the system – engine mechanisation unit, fuel metering unit, pump unit, as well as the fuel bypass valve – were tested.
“For the first time, all hydromechanical units of the SAU-8 went through a simulated fire in the engine nacelle. The result showed that a serious safety margin is laid down when creating new power units. These tests are another important step towards certification of the new Russian PD-8 engine for the SJ-100 aircraft,” commented Sergey Ostapenko, Chief Designer of ODK-Star.
The specialists of the Perm-based company created the automatic control system for the PD-8 engine within one year. In June, the development work was completed, and now preliminary and qualification tests of the units are being completed, including climatic, mechanical and other external influences. After the flight programme of qualification tests is completed, the units will be transferred from the status of pilot to serial production.
