Aux power - thrust

[Norman CYYJ]

How about a couple of hydrogen peroxide engines. There was a guy at KOSH a couple of years ago with this type of engine on his gyro copter. Each had an output of around 120 pounds of thrust. That would give you a ice boost on take off.

Nope, steam boost

The B36 jet engines used avgas

Beginning with the B-36D, Convair added a pair of General Electric J47-19 jet engines suspended near the end of each wing; these were also retrofitted to all extant B-36Bs. Consequently, the B-36 was configured to have ten engines ("six turnin' and four burnin' ", as characterized by Airmen Magazine), more than any other mass-produced aircraft. The jet pods greatly improved takeoff performance and dash speed over the target. In normal cruising flight, the jet engines were shut down to conserve fuel. When the jet engines were shut down, louvers closed off the front of the pods to reduce drag and to prevent ingestion of sand and dirt. The jet-engine louvers were opened and closed by the flight crew in the cockpit, whether the B-36 was on the ground or in the air.[23] The two pods with four turbojets and the six piston engines combined gave the B-36 a total of 40,000 hp (30 MW) for short periods of time.[24]

New Mexican, Bob Carlton probably has as much experience with this stuff as anyone. I remember having a conversation with him about the type rating issue but I have a poor memory and the links on the web are dead. I think it came down to working with the feds and getting a waiver.

how to get in contact with Bob?

Here's what John had to say when I asked about the necessity of a type rating in his new plane:

"Damon, no type rating required as it was certified as Experimental Exhibition group 2. There are different groupings of Exhibition and the jet is not considered a "primary" power plant. Basically the grouping tell the Fed which limitations to apply when drafting the limitations for the airplane. It was a really complex process to get the paperwork for this airplane."

So it seems to me if you wanted to add a turbine to your RV, you might have to re-certify, and it would not be a simple process.

Typo meant nice boost, thanks for catching that. If you did use it in the cold air you might leave a trail of ice or make great snow flakes.

I spoke with the FAA today and reviewed the concept. They believe it is doable with a Letter of Authorization. No multi-engine or turbine rating required since the turbine is on center line. The first step is to fly with a mockup to determine drag and handling characteristics. Insurance is possible and they can work with me from AIG. Vans said they don't know what thrust is required at best glide speed.
