Corolla-powered C-170

Post by n2582d »

This video shows the plane is first flying without the cowling on then switches to an airboat cruising a river and finally back to the 170 landing with the cowling on. It would make for an interesting article in the 170 News. The airboat was used for testing the engine and prop speed reduction unit.

Edit: Here's a Google translation of the YouTube text:
In this video we show the softness of the match, the absence of leaps and engine operation, smooth, and also show a flight without hood, working perfectly, this engine we regulate electronically with automotive gasoline and left with 140 hp. We also show our bench testing, or be a Hovercraft we use in the Pantanal, where they are tested every prototype gearboxes. Every box in the development phase through the Hovercraft. test at least 50 hours of hard work is done, in various engine speeds and only after this period is that the case goes to a plane, oh yes it gets off the ground. With that try to prevent the early hours to be tested in the air. Contact via email - luis.fernando@fretao.com.br

Here's a view of the other side of the engine. What I don't see is any radiator. This is the Google translation of the Portuguese of the YouTube text:
This is the fifth flight made with the engine Corolla 1.8 and Reduction box with Progressive torque. (Spinner Carbon Fiber made by Airfox Atibaia) With the progressive torque you give match and the propeller is stopped only after the box will transferring power to the propeller, reaching the maximum torque at approximately 1500 rpm. With this mechanism the box does not suffer the engine fits in the game and when you turn off the same, saving all the equipment. Note the pleasant engine noise, it works very smooth, and the box has already been tested in another plane and was good. We will test more and observe the behavior more hours. Every time we called this engine the heart beats faster, it's a special thrill to see it working, because it is a relatively inexpensive motor consuming a combustible also less expensive and may in the future use alcohol. We are studying the possibility of a reduction box for the Honda Fit. The next will be machined in CNC. Contact via email - fretao05@terra.com.br -

Gary,
I also wondered about the radiator so I stopped the first video at 15 seconds and noticed the big water hoses running down to what appears to be a radiator mounted flat with a cooling duct running towards where the lower nose bowl would be if it were installed, where on a normal 170 the carburetor cowl inlet is located.

Arash, About a minute into the first video, in the text, there's a reference to a diesel. Can your boss translate that for us? BTW, you've got my kind of boss! "YouTube at work? As long as it's plane-porn it's not a problem!" :D

John, I see the hose but one would think there needs to be more radiator surface area than what is seen in the video. Compare that to this VW 1.9 liter turbo diesel installation in a 172.

Gary,

In the diesel install pictured above you have 1 radiator and 1 intercooler. Turbodiesels are commonly intercooled (the Austro and Continental/Theilert ones are).

DEM,
Yeah, having three TDI's in the family I'm fairly familiar with them. 50 mpg is good!

Granted, a normally aspirated Corolla engine doesn't put out as much heat as a turbo diesel, but I still think this guy in Brazil must have more radiator than we can see in the video.

There are several video clips of this 172 in Finland with the TDI conversion. Here's one.

I am puzzled

I see a C170 with toyota engine take off and fly WITHOUT the nose cowling.

Moments later I see the C 170 execute a wheel landing WITH the cowling installed.

I drop a few screws during installation in in the hanger

Can someone explain?

Sure, either they cut to later footage or more likely they installed the cowl mid flight. Granted the later being a bit more tricky given the proximity of the cowl screws to the turning prop on the early cowl design.
CAUTION - My forum posts may be worth what you paid for them!
