Cobham offers a range of robust drogue solutions to suit
different customer requirements for hose and probe refuelling.
There are currently 2 categories of Cobham drogue; Fixed Geometry
and Variable Drag Drogue (VDD) covering the low and high speed
flight envelope.
Cobham's latest drogue designs all have unique patented low
Foreign Object Damage construction which eliminates parts that
would cause receiver engine damage in case of breakage.
Fixed Geometry Drogues are suitable for refuelling within a
specific speed envelope. Variable Drag Drogues on the other
hand employ unique technology which allows for a stable platform
for refuelling over a wide speed range:
- Low speed VDD: 100-180 kts (Compatible with helicopter and tilt
rotor probes)
- High Speed VDD: 180-325 kts (Compatible with NATO STANAG 3447
compliant probes)
- Variable Speed VDD: 105-215kts (Developed for the 48-000 pod on
USAF C-130 Aircraft)
An All Speed VDD is in development to provide a single fast jet
and rotary wing refuelling solutions.
