Is your platform suitable also for designing a high performance competition rc glider?

Thank you for a very very insightfull video! I design and build rc aircraft and was already loaded with a little knowledge but your methodical comparison of airfoils is very welcomed by me and is a very good approach.

Most valuable video for airfoils selection on KZbin Thanks allot ❤❤

Have you ever heard of the Kline Fogleman Airfoil? We introduced a step that traps a vortex which then becomes part of the airfoil and reduces some of the friction because it is air against air. It has been tested on Darrieus Wind Turbines successfully. It has only taken fifty years to gain some acceptance. A B S T R A C T This study provides a detailed analysis of the aerodynamic performance of various airfoil configurations, focusing on lift coefficient, stall characteristics, and maximum lift-to-drag ratio. The investigation includes the NACA23012C profile and configurations with different step geometries, ranging from one-step to five-step designs. Experimental measurements were conducted using awell-equipped aerodynamic laboratory, Institute of Aviation Engineering and Technology (IAET), Giza, Egypt. The lab features a wind tunnel, propeller test rig, and data acquisition system. The experiments were conducted meticulously to ensure accuracy and reproducibility, with a standardized method employed for uncertainty analysis. The results reveal distinct aerodynamic behaviors among the different configurations, highlighting the significant impact of design variations on aerodynamic performance. Notably, the three-step configuration consistently exhibited high performance, with a competitive or superior lift coefficient across a range of Reynolds numbers, showing an improvement of up to 35.1 %. Similarly, the four-step configuration demonstrated substantial increases in lift-to-drag ratios, reaching up to 53.2 %, while the five-step configuration exhibited varying trends with a minimum drag coefficient. The study also investigated stall characteristics and sensitivity to Reynolds numbers, revealing the complex trade-offs inherent in airfoil design. The findings provide valuable insights into optimizing airfoil performance under different operational conditions. Additionally, the adoption of two and three stepped airfoils resulted in significant reductions in blade material and associated costs for turbine blades.

Great explanation

Very cool platform, but unfortunately not available for my country.(

This company is amazing and i would love to reach out for help in my projects

фуфло

ты не умеешь это делать , абсолютно бестолковое видео . Кнопкодав мамкин без теории и практики работы

Real good.🎉🎉🎉

Bernoulli has nothing to do with lift.

mastering airfoil selection for fixed-wing drones. In our previous video, we covered the basics of how airfoils work

Thank you

yo- beautiful shots-

Great video, unfortunately a very incorrect definition for lift :(

Awesome video for engineers thanks!!

05:39 You are missing something. When calculating the CL and CD it is not by the chord c, but by a surface of reference. Otherwise, the dimensional analysis and results don't check.

Thank's for sharing.

amazing, is this simulation environment available now?

What payload is that, an EO9XX or MWIR payload?

Can you please explain the types of air foils used in aircrafts with their properties

Absolutely interesting video and very broken down!! 👏👏

The correct lift equation has the aircraft wing area and not the wing chord

Buen Hecho Juan. Gracias.

SIMNET, I love your channel so much, I just had to subscribe!

Great video!

2:25 You should specify it better. From your description you can have a relatively thin (5-6%) undercambered airfoil and the max difference betwwen upper and lower surface would make it something like 7-8%.

Don't you mean an aerofoil?

Very useful and knowlwdgable video I must say. I was researching the resources to fairly design the airfoil and came across your video series. It cleared quite few questions for me. Thanks a lot for making this video series and will be waiting for new videos. 🙌

The video touched on the subject but didn’t actually talk about it. That’s the forward shift in CP with increase of AOA. Dealing with the effects of camber on the pitch of the aircraft, maintaining stability without losing efficiency is a major design challenge and something for consideration when choosing the overall aircraft configuration. It’s actually possible to achieve aerodynamic instability with dynamic stability at the same time with no moving parts.

Thanks, this is a well-presented video. Looking forward to whatever else you produce on the subject of low-speed aerodynamics.

Very good video! I like it a lot. Can i make a suggestion to change colour of airfoil and graphs for brighter for better visibility of diffrences :-) Good luck with Your project!

Easily the most comprehensive video on the intenet. I've been searching for something like this for weeks, imagine my surprise seeing this video was only a day old. Subscribed!

Amazing! Well explained

Thank you for sharing.

This is super cool

Waooo

Thank you for info been searching for right one
