Remember Dyna-Cam?

[hevansrv7a]

I discovered this site:
http://www.axialvectorengine.com
which appears to be the new owner of the Dyna-Cam technology.

They are claiming that a small engine (<100 pounds) will produce 650 foot-lbs of torque while yielding 200 HP (which means very low rev's - I estimate < 1800 rpm). They are also claiming fuel efficiency improvement over traditional engines of >40%. But wait, there's more: it will run on diesel or jet fuel if gasoline is not available. And it doesn't need a starter!

The Dyna-Cam was real and powered an airplane for a while. The new owner of the technology doesn't mention aircraft.

I wonder if that's the company that was in Torrance,CA about six years ago and they were looking for a donor C-182 for the $35,000 prototype to fly around in?

Dyna-Cam was a real engine in a real airplane, but my memory is of a Cherokee - not really sure.

The inference one draws from the above article is that the current version is mechanical vapor ware with the purpose of consuming venture capital. That's a pity - the underlying basic technology is probably sound. I remember a "swash plate" engine in Popular Mech. or Popular Sci in 1961. The shape, power-weight ratio and torque characteristics make it promising for GA.

I don't think axialvectorengine.com is the same design as dyna-cam which was around a long long time ago. I guess it will be around some more? The Dyna-cam was similar but different configuration from my memory. Any attempt to Google Dyna-cam ends up leading to a dead link? I guess it's dead.

My understanding is that Dyna-cam is - was a FAA certified engine.
RV9-A 51HS (res) maybe this summer

The Dyna-cam engine was: 1) Real, 2) Certified, 3) Flew, 4) Was heavy for it's power, 5) Had cooling problems (notably differential heating problems).

Dyna-Cam was, as stated above, real, certified and flown. Axial Vector is the new name of AeroMarine which purchased Dyna-Cam's physical and intellectual assets and claims to have improved upon it. That's the shame of all this - Dyna-Cam has no apparent future except via Axial Vector and A-V appears to be vapor. Note that there are no photos on the site, only sketches.

A-V appears to be vapor

The vapor part explains it.

I was really wondering how to get 96% eff and 1+ HP per cubic inch.

Thanks, I guess we can look up the patents some how and see the detail. Interesting. So if it was heavy, low power and had "thermal problems", why is it back? To get investors. G
