Mercerization is a process applied to cotton - to increase luster. it was found that the process also had secondary benefits: the mercerized fibers were able to absorb more water, and absorb more dye, The difference is dramatic: mercerization increases the absorption of dyestuffs by as much as 25%
There is actually a crash report for tail number NC3734 ( 1943 ) the plane is an Interstate S-1A-90F " Narrative: Lost control in a turn at 15 ft after a touch and go on an auxiliary airfield, left wing hit the ground and the aircraft crashed. "
American pilot does not know what to do to start this engine. It's the same thing with all the other radial engines. Bunch of ignorant about staring these engines. They are all experts about safety though 😂😂😂😂😂
To instill confidence in your clients (and impress the girls), guarantee additional strength in your straightened bent tube repairs: leave the blocks and 'C'-clamp in place. For extra peace of mind, and a knowing wink from your boss, be sure to weld the threaded portion of the clamp to the 'C' arm, and safety wire the whole assembly to the Billings framus arm. Now you're cooking with plaster!
C.S. : "Should I do an update video?" ... Definitely Mr. Sturm ! I've been waiting for this for a long time. Nice to see the cub alive. I followed the whole development of your Cub on your website and youtube. Regards from baltic shore. Stay healthy ...
Great engineers , I wonder if they had any idea that the Cub would be an absolute icon , still to this day the most dependable GA aircraft and also copied
You'll spend 15 years at it off and on, waste a lot of money and time, it will take over a lot of your mind, you'll never fly, and in the end it just ends up as junk taking up space forever in your garage until it's sold off in an estate sale to a scraper. Or Choppergirl, who buys it for $38 off ebay. It still will never fly.
I’ve seen these in museums and always wondered whose idea it was to have the entire motor swinging around a stationary crankshaft. Weird idea, but then airplanes were less than 10 years old at the time.
It was for cooling. These engines were so inefficient and weak that standard air cooling wouldn't work. So increase the amount of air movement over the engine you have the engine spin
Everything was a work in progress. I think it's quite amazing how fast the engine evolved for all vehicles. Tjis was just the best they could do with the knowledge, design needs and industry they had at the time, we cant expect the designers to know how to make the most efficient vehicle without experience or time to test it through years of use. Just like the jet, they had to make a ton of less efficient jets before the f22 raptor and judging by its design, they must have been on to something because the radial engine looks very similar with cylinders in a circle, so I'm assuming that shape, is what played apart in the design. Like why they used a circular engine like radial or rotary instead of a car style inline or V piston engine in airplane in the first place. Sure there's a good reason why and this was the best they came up with at first, until they could get enough pilot feedback and troubleshoot mechanical failures to know what to improve on or scrap. Like exhaust in the face lol.
The rotary engine was invent in 1891 from the french motorcycle builder Millet and put inside the rear wheel from hes bike.Later was the design improved from Gnome to fit on aircrafts because this design was the lightest and the best cooled awailable, only in 1917 came much better inline water cooled engines like the 260hp 12cyl Renault use on the Bréguet 14 …
No throttle, basically just turned the ignition on and off. Lubrication was with castor oil, which sprrayed back in copious amounts, ensuring pilots never had to worry about being constipated.
If this was filmed in 1943 then these are probably being built for the Civilian Pilot Training Program. Only aircraft built for war needs were built during the war. Most Cubs at this time were being built as L-4s for artillery spotting purposes.
