Abstract
An air inflow control device (10) simulates flight-like air inflow conditions into the intake (36) of a turbofan engine (18) during static ground tests. The device (10) has a truncated spherical portion (12) with a circular opening that is closed by a bellmouth (14). The bellmouth (14) provides an inwardly projecting conical surface having a central high-lite and throat portion (28, 35) that permits air to flow from inside the sphere (12) into the engine (18).
