https://registry.faa.gov/aircraftinquiry/NNum_Results.aspx?NNumbertxt=818WM

BACKGROUND OF THE INVENTION

The present invention was borne out of frustration with the cost and inefficiency of the airlines' hub-and-spoke transportation model. This model was conceived by the airline industry, initially in an attempt to restrain passengers from using interline transfers to arrive at their destinations. It requires dense concentrations of passengers both at the relatively few hub facilities and in ever larger aircraft flying to fewer and fewer destinations. The inefficiencies for the traveler arise out of the time wasted traveling long distances from their true origin to the large hub or major airport, enduring the lengthy lines at check-in and security check points, and the ever-longer boarding process on the ever larger aircraft. In addition, the traveler must often fly to cities that are well out of the way to his final destination, and transfer with additional wasted connection times. The result is that for short trips (approximately 500 miles) average speeds reduce to the vicinity of 100 mph, and many longer trips that involve just one connection drop to 200 to 300 mph average. This inefficiency raises costs for the consumer, especially where the inefficiencies require overnight stays in order to catch connecting flights. There is an additional factor which is a disadvantage of the current hub and spoke system. The current system creates large concentrations of people, both at terminals and in ever larger aircraft, that create prime targets for terrorist activity. Larger numbers of much smaller aircraft operating in a widely distributed transportation system would present a more difficult target for any significant military or terrorist activity.

Clearly, there are compelling reasons for wanting an air transportation system that is economically superior to our current air transportation system in acquisition, operation and maintenance costs. To be a viable competitor, the system should have true origin to true destination speeds that significantly exceed current system speeds. It should require no additional infrastructure, and it should package passengers in small enough units that both the passenger load and the aircraft are militarily insignificant targets. To be truly competitive, it should provide non-stop transcontinental and intercontinental travel from any local airport to any other local airport. And ticket prices should be highly competitive with current average ticket prices.

Such a transportation system requires a unique aircraft. It must be capable of operation from any current airfield. Preferably, it would have operating costs well below current costs and competitive with commercial airliners, cruise at higher system speed than current commercial aircraft, have a longer range with full passenger and luggage load than most current business aircraft, provide passenger comfort comparable to commercial aircraft, and be capable of all-weather operation. The plane should also provide for ease of maintenance and require only a single pilot.

That looks like the Raptor and Glamorous Glennis got drunk one night and made a baby plane!

That's a big, ugly baby. Hopefully it has a good personality.

Below is an excerpt from this reference:
https://www.thedrive.com/the-war-zone/2 ... y-fly-soon
Quote:
The patent goes on to describe a notional aircraft that would cruise between 460 and 510 miles per hour at an altitude of up to 65,000 feet, yielding a fuel efficiency rate of between 30 and 42 miles per gallon.

Wait, what?

That sounds just as preposterous as Raptor predictions.

Rumor is it is sporting two RED 500hp Diesel engines...

I have a sneaking suspicion the polar of this door is going to be out of sight compared to anything in its class. 25-30/1 would not surprise me depending on best door holder.

Also expect when she comes back for sophomore year she's gonna shed a few pounds and may even have cleaner door lines still.

Big questions in my mind are door reliability and power transmission to the door holder. I think the door may way out perform what many think. The torque curve is a beautiful fit, and the turbo is gonna let her breathe up high.

We shall see.

Any video of the flight? Could not find any vids at the links. (maybe did not look hard enough)

Have to say the prop and airframe don't look matched regardless of powerplant.

Trying some math...
At 65000 ft 125 mph ias is 500. Mph tas.
Using the red sfc of .35 lb/hp/hr and 40 mpg at 500 mph we get 240 hp. 4 place plane at 110 Kias that seems reasonable if you can make the diesel run at 65k ft.
The red a03 is said to go to 50kft stock.
That is mach .75 so issues with both prop and long thin wing will be real.


If you can make the engine run at 65,000 ft, not sure you need any kind of exotic airframe.

Guess it's got just one in this one, but the rumor still says it's a RED diesel engine.

Red web site says it’s 12 cyl but both 6 cyl banks can run independent of each other. So it’s kind of a single and twin engine

It looks really expensive. Haha. But way cool.

Still can’t believe we don’t have modern engines to replace these old AVgas burners.

The RED diesel looks interesting. I’d love to see an analysis of what that powerplant would do in a Piper Meridian sized airframe. The 310 or 350hp gas recips were a little underpowered in the Malibu, thus the move to 500/600 hp turbines. But a 500 hp diesel recip would be interesting as a comparison to the turbine. Possibly “best of both”, similar efficiency to the Malibu at speeds like the Meridian.

Or, perhaps the weight/CG would not work in a Malibu derivative but a clean sheet design could get low end SETP speeds on recip fuel flows. That would still be interesting.

I am less sanguine about running a larger airframe at FL500 on that engine as the Otto seems to suggest. Much bigger engineering challenge.
