A piece of Sikorsky concept art from 1959 illustrating a commercial passenger pod for the S-60 flying crane helicopter. Into the 1960’s there were a lot of people thinking that commercial helicopter “airliners” would soon be a practical reality… and obviously, helicopters are perfectly functional in the role of hauling people to and fro, but the idea never really caught on. And in retrospect it’s not difficult to see why.

Compared to turbojet or turboprop passenger planes, helicopters are creakingly slow and quite short ranged. So the idea was that helicopter-liners would serve as short range feeder vehicles, transporting businessmen and the like from city centers to outlying regions. A popular goal was to fly passengers from the top of skyscrapers to distant airports, saving considerable time and trouble with ground traffic. But in the end, while helicopters could do that – as many a multi-millionaire with his own helicopter can attest – the cost was always high, and the noise of regularly scheduled very large choppers was excessive. There was also always the fear of helicopters this big zipping up and down the city streets, and building the infrastructure to support in-city commercial heliports just seemed like too much effort.

Somewhere north of 20 years ago I received a package in the mail from Martin-Marietta containing stuff on their then-current NIMF study. NIMF was a mangled acronym for Nuclear Rocket Using Indigenous Martian Fuel; basically a propellant tank, structure, landing gear and a nuclear rocket engine, to be used for landing a payload on Mars and for flying or hopping around. The propellant would be liquid carbon dioxide, easily compressed from the Martian atmosphere; the performance would be, by conventional liquid hydrogen nuclear rocket standards, reasonably awful, but it would be adequate to lurch back into Mars orbit or to do long range hops.

Two main designs seem to have been studied: a conical “ballistic” vehicle that would be a dedicated “hopper,” landing on its tail, and a winded vehicle that would land vertically in a horizontal attitude. This latter design was sent to me in the form of diagrams and five computer renders. The renders – early 1990’s vintage – came as viewgraph transparencies, clearly photographs of a computer monitor. The winged vehicle had simple shock absorbers for landing gear, terminating in dishes rather than wheels meaning that a rolling start or stop was impossible. The available information sadly doesn’t explain how the thing was supposed to land vertically.

The full-rez scans of the viewgraphs have been made available to APR Patrons in the 2016-01 APR Extras Dropbox folder. If you’d like to help out and gain access to this and many other pieces of aerospace history, please check out the APR Patreon.

And then there’s this. While I haven’t managed to get hold of the actual item, I have gotten full-color scans of this, in chunks. I am now piecing it together into one gigantic whole.

This photo was passed to me to identify. Much of it looks like the Grumman G-623 VTOL fighter concept from the mid 1970s (illustrated below), but the tail is obviously entirely different and the nose is much pointier. It’s my guess that the model might represent an early version of the G-623 design. Can anyone confirm/deny?

Below is an artists impression of the Bell D190B, a tilt-duct VTOL derived in part from the X-22. The D190 series, dating from the early 1960’s, was for a more-or-less common airframe design that could carry out a number of missions. Interestingly, variants of this design were considered for “parasite” roles. The aircraft could hard-dock to the underside of a C-130; the larger transport aircraft could then haul the smaller VTOL around the world, where it could serve as a rescue plane (note the rectangular hatch on the top of the fuselage). Another idea was for the small VTOL to serve as a crew or passenger transfer system for EC-135J (707 derivatives) flying command posts, including transporting VIPs (read: politicians) away from nuclear strikes to orbiting escape planes.

Sadly, while I’ve found many bits and pieces on this over the years, I’ve yet to come across good design data. If anyone has anything, I’d love to see it.

A piece of Bell Helicopter artwork depicting their design for the LHX competition, what became the RAH-66 Comanche. Note that this design featured unusual curved, swept sponsons and a NOTAR (no tail rotor) tail.
