The flight test program of the two new inlet systems CVI and HASI started in the second week of August 2013. The new concept of shrouded intakes were developed and designed by enviscope. The shroud is necessary for intakes where proper alignment of the airstream towards the probing tip is requested. This is crucial for aerosol probing (HASI) and the Counterflow Virtual Impactor (CVI) principle.
The start of the flight test program was an exciting milestone towards the certification of the intakes together with our partner Gomolzig Flugzeug- und Maschinenbau GmbH. It was the first time that a shrouded intake was flown on HALO with its performance up to high Mach numbers. It was also the first time that an intake was flown on a top-viewport on HALO.
The results of the flight test program were completely satisfying. No vibration and buffeting have been monitored. Both intakes have passed the complete range of velocities and altitudes.
CVI and HASI intakes will be fundamental parts of the upcoming ML-CIRRUS campaign in late January of 2014.
