I saw Kermit fly this plane at FOF. He flew over really slow, cut the engine, let out a huge "Yaa whoo" to which the whole crowed laughed, restarted the engine and carried on. His passion for aviation inspires me.
+Wout Wynants www.allstar.fiu.edu/aero/airflylvl3.htm Bernoulli's principle as a primary cause of lift is actually a widely perpetuated myth. Check out the link for a detailed analysis of the actual cause of lift.
I was part of an elementary school trip in the 4th grade (2003-2004) to fantasy of flight. I remember seeing the storch fly that day. As an aviation lover, that was easily the best field trip I've ever been on.
Kermit, thank you so much for your informative video. I've always wanted to be a pilot but unfortunately life happens. I've learnt so much from you. I'm 72 now so the chances of me getting a pilot's licence now is very slim, if not impossible. RU-vid has made it possible to at least experience some the thrill of flying. Many thanks
Your briefing on aerodynamics is so simple, through and complete that even the novice will walk away with a deeper understanding of the basics of flight as well as what makes this beautiful ugly duckling amidst the sleek fast war machines so special. An inspiration to STOL flight engineering. Again Kermie, o7 ~ your neighbor
Thanks for doing this! This aircraft and the Connie are featured throughout W.E.B. Griffin's Honor Bound series. It is a special treat to ride along. Thanks Kermie!
Very cool video again Kermit. Can't wait for part three. Point of interest... I posted part one to my Facebook page and a friend freaked out. Says his Grand-dad was on the design team for the Fieseler Storch. Adolf Zeilinger was his name. Very cool that so many years later there are still some ties to the ingenuity and the people of that day. Thanks for the video Kermit!
always been fascinated by this aircraft.the walk around and information really brings it to life! excellent knowledge Kermit and thankyou for uploading this :)
Just love how you maticilously check the video before uploading, and adds explanation arrows for trim, indicator and flare gun, which we didn't see clearly on the cam first time👍👍👍
Great video! Thanks for letting me see inside the Storch, one of my favorite airplanes. Thanks to Dr. Winter. As far as the explanations, I don't have any problem with them and I've been a working Flight Test Engineer for a couple of decades.

Kermit well explained you gave lesson very much in layman's terms easy to follow if the student was paying attention Im so getty and thrilled listening while you are much a teacher that could prepare someone flying. All day I'm to words that teach me! This information and show telling helps me on building accurate models! 👏😋
SO much information compared to your other videos. I can tell which plane's your favorite! lol. I'm going for my Student Pilots License! Just wanted to share that. Going through my ground school dvd's for the second time. Between Fantasy of Flight, my Grandpa, and my Cousin, I've got a lot of inspiration. Thank you Kermit!
I love the Storch, it reminds me of a plane I had a few years ago. It was an Ison/TEAM Himax 1700r with a completely custom undercarriage relatively similar to the Fi156. It was much shorter and had a strange yaw but was a blast to learn to fly in. I should also ad that the first time in my life I was ever in an airplane was in that single seater. Craziest thing Iv'e ever done was joint the Wright flyers club.
Reminds me of a story I read about a couple of Airline pilots who bought a Piper Cub. No High altitude; no turbos, no jet engines..no electronic navi...just the simple joy of flying.
Amazing sound from the inverted V-8 engine. I can believe how smoothly it runs. Notice the stick, instrument panel and other parts inside the aircraft. Nothing is shaking! No vibration as in a small Cessna or Piper aircraft with an opposed 4 cylinder.
A British aircraft manufacturer - Handley Page - developed Slots from 1919 and fitted them to its airliners in the 1920's and 30's. They patented them and licensed them all over the world. They also developed Slats from the fixed slots.
This plane always reminds me of the large plane that crashed in the Alps...and a pilot, I cant recall his name, had one of these planes... Others tried to save the people trapped by the wreckage with dog sleds and whatnot. This plane because of the short take offs and landings saved everyone in a few hrs. A blizzard hit the next day and buried the wreckage, they all would have perished. Great pilot, story, and plane
I wish I'd known about those molecules holding hands to explain Bernoulli's principle when I was teaching physics at Stark State College. I'm sure the students would have loved it. I'd like to see Dr. Fieseler get credit for the innovations on the Storch, rather than "the Germans". One last comment, the name of the temperature unit in the metric system was changed in the 1960s from centigrade to celsius. It was done to honor a Swedish physicist, Dr. Celsius, who did a lot of research on temperature measurement. When written in text, the name of the unit is spelled with a lower case letter, while the man's name is written in upper case.
FYI from Wikipedia Slats were first developed by Gustav Lachmann in 1918. The stall-related crash in August 1917 of a Rumpler C aeroplane prompted Lachmann to develop the idea and a small wooden model was built in 1917 in Cologne. In Germany in 1918 Lachmann presented a patent for leading-edge slats.[4] However, the German patent office at first rejected it as the office did not believe the possibility of postponing the stall by dividing the wing. Independently of Lachmann, Handley Page Ltd in Great Britain also developed the slotted wing as a way to postpone the stall by delaying separation of the flow from the upper surface of the wing at high angles of attack, and applied for a patent in 1919; to avoid a patent challenge, they reached an ownership agreement with Lachmann. That year a De Havilland DH.9 was fitted with slats and test flown. The HP 42 were fitted with Slats
Again thank you for making and sharing these videos with us. Us germans are pretty good in making tools operate good but the tendency to use it to make weapons with that engeneering approach isn´t what i´m proud of...
I love these videos. Just occurred to me that anyone watching these being recorded with the cap-cam must think, what the..? Man talks to himself and waves arms, then takes off in the plane, heh.
The Coanda effect describes the tendency of a fast moving fluid like air to stay attracted to a curved surface. And in the case of lift and air foils it effectively pulls the wing into the faster moving air above the curved surface of the air foil. And like you said when you use flaps it increases the curvature of the wing therefore increasing lift. But it is mainly increased by the Coanda effect and additionally by the Bernoulli principle/effect.
The air does not speed up when the relative wind enters the slot, it slows down (higher pressure, lower speed, lower pressure, higher speed), which aids overall lift. Additionally the higher camber (less curve in the leading edge) 'main' aerofoil behind causes less seperation because of the (at the time not properly understood yet) coanda effect, the tendency of air (any gas/liquid really) to follow the boundary layer. Its basically a slow speed wing with a high speed 'slot' in the front which changes the characteristics of the aerofoil (primarily the leading edge) behind in level/trimmed flight.
I got interested in the Storch after reading about the role it played in the rescue of Mussolini at Campo Imperatore. I got kind of obsessed and qactually created a mission for MS FSX flight simulator recreating the entire mission with a glider towing take off from Practica Di Mare near Rome where the SS officer Otto Skorzeny and the elite paratroopers led by Harald Mors executed a glider assault on Gran Sasso. Much was made in in subsequent reporting that the storch was grossly overloaded with Skorzeny hopping in the back with Mussolini to grab the first credit and get off the mountain with Mussolini in the hands of an SS officer. Politics aside, the Storch was claimed to be a one passenger plane, but in actuality was used as an air ambulance carrying three, pilot and two passengers. (and the model used was a lighter liason version without weapons attached.) Even though, taking off from the top of a mountain in this configuration was risky, but it was as history reports a success. In the simulation which does account for density altitude, if you load the plane as it was in those times it it is a dicey take off. credit to the pilot Hauptmann Gerlach for executing the take off under less than ideal conditions, however had it crashed two rascals would have died, Skorzeny and Mussolini. :)
One of my hot air ballooning buddy’s had a Storch. He lived in southern Ohio, Lebanon and flew from his farm. We flew hot air balloons from his farm on a navigation task to a predetermined target. He took his Storch to Indianola IA back in late 80’s He was doing “flight safety watch” of a task during National Balloon Fiesta. The weather actually turned bad during flight. One of the competitors had his burner mount fall on his head during a hard landing from the Bad weather conditions. A medevac helicopter from Des Moines took him to ER. Fortunately his injury was mainly superficial. He flew the next day in the 4th day of competition. I lost touch with my friend that had the Storch. This was 40 yrs ago and he likely has passed.
Common misconception on airfoil lift description. There's nothing in the laws of physics that says air molecules have to return to be next to the same air molecules as before. The speed of the air above the wing DOES increase, but not for the reason stated in the video. Great videos nonetheless!
+zekezero12345 www.allstar.fiu.edu/aero/airflylvl3.htm Here is a very good explanation. Bernoulli's principle as the primary driver of lift for flight is a widely perpetuated myth.
zekezero12345 To be honest, I'm not quite sure on that one. It's likely more that the airflow on the underside of the wing is slowing down due to compression than the airflow above speeding up. Either way you get the relative air speed above the wing being faster than below the wing.
Actually it isn't, and you can prove it by holding the narrow edge of a piece of paper under your mouth horizontal, so the rest of the paper droops down, then blow across the top of the paper and watch it rise up. The Bernoulli principal is instrumental in the function of carburetors and other devices using a venturi. I just stated that the air molecules flowing around a wing don't meet back up with their prior neighbors.*****
+Cody Wagner +zekezero12345 The short explanation is that the air is actually accelerated DOWN over the top surface of the wing. This is because compressed air is viscous and, due to the Coanda effect, wants to "stick" to the surface of the wing. Only the boundary layer is affected by the Coanda effect, however because the boundary layer air is pulled down, the air above it must move down to replace it. So when you end up with is a sort of air scoop above each wing which reaches highest in the middle and tapers toward the edges. It is this large mass of air being directed downward that produces most of the lift responsible for flight. When you have boundary layer separation, as you do during a stall, the scoop is disrupted and air is no longer accelerated down over the surface of the wing. The slots work so well because, by directing air over the top of the wing they reinforce the boundary layer flow and augment the Coanda effect force to prevent separation of the boundary layer until much slower speed. Incidentally, this is also why vortex generators work. The vortex created at the tip of the fin mixes higher layers of air with the boundary layer essentially inflating the boundary layer (which is normally very thin) by mixing it with smooth air flowing over the leading edge of the wing. This has a somewhat smaller effect than slots but still significantly reinforces the Coanda effect force to hold air in a smooth flow over the wing.
The basic math is;static pressure plus dynamic pressure is a constant so for the bottom air particle going along the bottom of the aerofoil Ps14.7+ Pd0=14.7 lbs of pressure on the bottom of the wing .Because the air particle moving over the top of the wing has to move away from its brother ,it is given an acceleration and because it is accelerated it gains Dynamic pressure thus to maintain the constant, the static pressure on top of the wing decreases and the wing is pushed up because of the differential in pressure
Is Kermit giving the Germans too much credit for the invention leading edge slots? I have always thought that these slots were first used by Handley Page (a UK company) and were often referred to as "Handley Page Slots" as a result. They built an experimental aircraft in the 1920s called the Handley Page HP39 "Gugnunc" to test the principle. It was a one-off prototype and is today on display in London's Science Museum.
nicht anfassen! Do not touch - what is that about? I see it moves when you move the ailerons. Was ist Das? after i watched for a bit longer the airfoil angles of attack made a lot of sense. Steven Groves heli pilot RIP would appreciate. Thank you Kermit,
The air on top of he wing is not holding hands with the air on the bottom, and they actually do not arrive at the back of the wing at the same time. There is no rule the air on top meets up with the air on the bottom at the same time at all. Air on top does have low pressure, and the higher velocity air clinging to the wing top slides down off the trailing edge, creates a downwash and a reaction. So high and low pressure and downwash create lift. Flaps increase the downwash. Slats/slots maintain laminar flow at high angles of attack. Stall is turbulent not laminar flow, thus no downwash. But it's a lot like the right and left hand electrical rules, thinking of how electrons move is backwards from what originally thought, but it doesn't really matter the rule still works.
"Nicht anfassen"... what aren't you supposed to touch? It's just a tube...? Also, it occurred to me (I'm slow but eventually I catch up) that the slots do the same thing as the jib of a sloop rigged sailboat.
Imagine a 200 lb man climbing into the cockpit and getting into the seat. What's he going to grab to pull himself into the cockpit; the tube, of course and it definitely looks flimsy enough to bend easily.
I'm sure sir that you are wrong in your statement about the Storch being the first production aircraft with full width slots - I just can't prove it (yet!). They were invented by Handley Page in 1919, & proven experimentally on a modified DH9. The also developed the first controllable slots. I felt certain that a pre-WW2 Junkers (airliner/mailplane) was the first but have been unable to verify this.
In Part One he said that there'd probably be a lot smoke at the start, because he hasn't flown it for a long period of time. In Part One it is explained
engine cylinders are inverted, i.e. pointing downward. Oil has a tendency to seep into the cylinder heads when sitting idle and then burns off when engine is first started, hence the smoke. it's also common in radial engines. If too much oil collects in the cylinders it can cause a hydraulic lock and damage the engine. Its common practice on these engines to pull the engine through by hand before starting to check for hydraulic locks.
Hm... as far as I know there's nothing that dictates that the two air molecules 'holding hands' before hitting the front of the wing will ever meet again. Lift seems to be generated solely by the angle of attack causing a downward motion of the air (action vs reaction). Which is why some airplanes can fly inverted.
