Description When the US Army came-up with the idea of a "Flying Jeep" (a small VTOL utility aircraft) in the 1950s, all sorts of wacky flying machines were offered. They varied widely in practicality (and silliness), but one clearly stood-out from all the rest; Avro Canada's "Avrocar".

The Avrocar was promised to be all things to all people. It was supposed to fly both horizontally and vertically with the greatest of ease, to cover a very long range, reach a high service ceiling, reach tremendous speeds, carry large loads for it's size and weight, and so on. It was also promised to herald a technological revolution in aviation unseen since the advent of the jet engine.

But more importantly, the Avrocar was a Flying Saucer. No, I didn't make that up. I reiterate; the Avrocar was --- a Flying. Saucer.

Well, that's one thing, but as wacky as the idea was, it was also a 360-degree dead end. This is because the Avrocar couldn't actually fly at all (does that mean it's just a "Saucer"?), despite many dogged attempts. I kind of spoiled the outcome of this episode by telling you that in the introduction, but this story is still an important cautionary tale in aeronautics, engineering, marketing, and project management.

Also, it was a big enough imbroglio that I had to make this episode a 2-parter, so be sure to watch both!

I'll post my sources in the description for Part 2.

Lastly, note that I once again had editing support from meaninter03 on the script for this episode!

This was unexpected. 

But yeah, this one was a blatant disaster.

This series will include all sorts of military flying machines gone wrong, including rotorcraft, VTOL projects, and so on. I've been meaning to add some helicopters to the queue, but I never seem to finish any of their profiles.

Interesting. 

I can't wait for more episodes.

I'm constantly reminded of the F-35B's lift fan when I read about the Avrocar's turborotor. Do you think the US Navy would've managed the program better, as a predecessor to the LCAC? (Managing it as an AV-8 or "Harrier" predecessor, is obviously an invitation for disaster, when you consider the fact the AV-8 itself is a disaster- see www.pulitzer.org/archives/6722.)

I don't think the Avrocar would have fit the bill. This type of aircraft uses a broad, central lifting fan and a saucer-shaped aerofoil; two features that are bad enough on their own, but work even worse when combined.

As for use as a a load-bearing hovercraft, the Avrocar was barely able to move a few feet at a time before losing lift, and it could barely support the weight of the pilot and a full tank of fuel. Even if we excuse that, there's the problem of getting enough power to lift a useful payload, and it's effect on the stability of the machine's "flight" (I use the term loosely). Typically, a more powerful engine is a larger, heavier, and thirstier engine, forcing the airframe to be dramatically scaled-up just to fit the engines, which also makes it immensely more expensive. That also means you have to strengthen the airframe, cram-in more fuel cells somewhere, add more stabilization features, and so on, making the airframe even heavier and more expensive.

And on and on. This is called the Cost-Size-Complexity Spiral.

As for the Harrier, you might just see an episode on it.  XD
