LRI-AAST: L2 laboratory: PROP1 and PROP2 test cells
| Lab | Equipment | Application |
|---|---|---|
| L2 | PROP1 – propeller test cell 1 PROP2 – propeller test cell 2 |
Test cells are designed for complete testing of turboprop engines up to 1500 kW at a stationary site. It allows not only monitoring and capturing of vibration characteristics of individual engine parts but also characteristics of all engine operating parameters (temperature and pressure, power, consumption, noise, etc.). |
Location
Two mobile propeller test stand laboratories for turboprop engine are located at the Hradec Králové Airport. The laboratories
are equiped with a sophisticated propeller system and a stationary site reducer, the HW and SW equipment of the test rooms
enables monitoring and sensing of the vibration characteristics of individual parts of the complete engine (including the
drive propeller).
Paratemeters
| Power of test engine | to 1500 kW |
| Air flow | to 200 m3/s |
| Exhaust gas temperature before dilution | to 750°C |
| Maximum flue gas temperature after mixing on the corridor wall in reverse mode | 130°C |
| Propeller to diameter | to 2667mm |
| Thrust | to 22000 N |
| The reverse mode corresponds to 1/3 of the forward flow and thrust values | |
PROP1 and PROP2 test cells are identical, each has own control room and conference room, fuel management, compressors and other key infrastructure supporting equipment.
