US Army VTOL research designations (VZ)
Permalink  
 


VZ was used as a designation prefix for VTOL design studies including the Flying Jeep and other related lift-fan/shrouded rotor platforms in the late 1950s (Avrocar, Pawnee etc. ) as funded by the US Army.

VZ-1 - "Pawnee" - Hiller 1031 / HO-1

VZ-2 - Vertol Model 76

VZ-3/VZ-3RY - Vertiplane - Ryan Model 92

VZ-4/VZ-4DA/VZ-D4A - Doak Model 16

VZ-5 - Fairchild Model M-224-1

VZ-6/VZ-6CH - Chrysler flying jeep

VZ-7/VZ-7AP - Aerophysics (Curtiss-Wright) flying jeep

VZ-8/VZ-8P/VZ-8P-1/VZ-8P-2 - "Airgeep"(I) - Piasecki PA-59/59K (Model 59K) "Skycar" (USN: Model 59N SeaGeep (I))

VZ-8P (B) - "Airgeep II" - Piasecki PA-59H (Model 59H) AirGeep II

VZ-9/VZ-9-AV - "Avrocar" - Avro Canada Project Y / Project Y-2 (USAF: WS-606A / Project 1794 / Project Silver Bug)

VZ-10 - Lockheed V-4/XV-4 "Hummingbird" (redesignated in 1962)

VZ-11/VZ-11RY - Ryan XV-5 "Vertifan" (redesignated in 1962)

VZ-12 - unused - would've been the Hawker-Siddeley P.1127

.........If you notice sometimes the designaton is seen with additional letters after the number. These denote the company involved with the design.

AP = Aerophysics (division of Curtiss-Wright)

AV = Avro

CH = Chrysler

D/DA = Doak

P = Piasecki

RY = Ryan

Thanks for the suffix key at the bottom. I had no idea what those meant but now it looks so obvious. With that could we safely assume that the others carried these too? Or was this a practice adopted later in the program's life?

Wow, that's a fact that slipped by me too. Glad to have that bit of ignorance resolved.

 Good question, I have to do a bit more research on that and get back to you.
