CORE COWL FOR PRESSURIZED AIR DRIVEN TURBINE POWERED SIMULATORS HAVING ANTI-ICE TRAILING EDGE

摘要

An engine simulator (2) for wind tunnel models comprises a turbine (4) having an inlet (6) for a pressurized fluid and an outlet (8) for an expanded fluid, a core cowl body (10) arranged downstream from the turbine (4), the core cowl body (10) having a core cowl trailing edge (12), and an outer nacelle body (14) that at least partially envelopes the core cowl body (10) with the formation of a gap (16) and envelopes a fan (18), which is coupled with the turbine (4). The core cowl body (10) comprises at least one outer heat conducting material layer section (32) extending up to the core cowl trailing edge (12) and having a first thermal conductivity coefficient, and at least one inner heat insulating material layer section (34), having a second thermal conductivity coefficient. The first thermal conductivity coefficient is at least 100 times the second thermal conductivity coefficient.
