Tilt Rotor Designations Query
« on: December 03, 2017, 05:46:29 AM »
Is there a designation sequence for tilt rotor aircraft ?  We have a V-22 and there's the V-280 which don't seem to be in any sequence. What would the next number (numbers) be for an 'in-service' aircraft ?  What would an escort for a V-22 be designated as ?

V-24?

I really have no idea.  The Pentagon seems a law onto itself as far as designations go.  We do not know what has already been designated (but not developed), so I'd just pick a designation x numbers in advance of the known one.

Well, I was thinking as there were AH-1's (Cobra) which escorted UH-1's (Huey), would an escort V-22 be an AV-22. But then the AV designation is for fixed-wing aircraft, right?

Of course you could say the V-22 is a fixed-wing too ----  :-\

V280 is simply the Bell name that marketing is selling it as.  Tilt-rotor aircraft generally fall in the "V" designator along with other stol and vstol aircraft.  Should the V-280 win the FVL competition, you will probably see a firm military designation at that point (any bets as to whether they use "V-28" for a production one?).  An armed, gunship variant to escort the V-22 would likely be an AV-22 (probably need a new armament carrying fuselage to do the escort properly - would not be that difficult since wings and fuselage are built-up separately and only mated on final assembly).  Other capabilities are more of a RO-RO style, like the aerial refueling system or a tailored MAFSS for V-22 usage (tempted to model that one in USFS markings).

As the AH-1 was, essentially, built around the workings of the UH-1, the V-22/AV-22 designations make sense. :smiley:

But then the AV designation is for fixed-wing aircraft, right?


this is all squadron and not aircraft designation, but might help your project still:


VA- is a squadron designation. V= fixed wing. A= attack Example VA-85. Throw in a M for Marine squadrons. Example VMA-311



When Medium Heli squadrons converted to Osprey they went from HMM (Heli, Marine, Medium) to VMM (Fixed Marine Medium) but since its still in the Helicopter format ( _, Marine, Size) everyone knows its an osprey since helicopters are Light (HML), Medium (HMM), or Heavy (HMH). But Fixed wing (like actual fighters)is not designated in such a way (VMA, VMFA, VMAQ, VMO)

Current Huey and Cobra Squadrons are designated HMLA (Heli, Marine, Light, Attack) So an "Attack" Osprey squadron would become VMMA (fixed, Marine, Medium, Attack) VMMA would work since fixed wing squadrons (like actual fighters) are either VMA, or VMFA, (VMAQ will be a thing of the past here possibly. VMO already is)

I hope this makes some sense!  :-\
