Lol, confusing isnt it ......

Hi, I have undertaken a project to relieve stagnation point pressure on a NACA 23015. Experimentation is complete, However the only readings that could be taken with the available apparatus was static pressure at the LE to find the point. This may seem trivial to some but what is the static...

I noted that this is appendix IV, is there any text to go with the data? sorry i am not lazy just cant find the damn stuff :). thanks again Craig

this information was usefull SWhit, I have the book theory of wing sections by Abbot, Do you know the page number, i have checked the index no luck :( cheers mate Craig

Hi all, I am writing a project on the airfoil and have modified the NACCA 23015. However I am finding it EXTREMELY difficult to find data on the airfoil. I have the co-ordinates but have no idea on its application and its properties. Any assistance would be appreciated. Craig Thomas...

I did not consider this, What kind of energy if any does the stagnation point posses? My mentour told me that this kind od experiment would reduce the wake region. by comparing the modified aerofoil with the unmodified wake region i should have some sort of differential equation. I am...

Thank you for your reply, Yes i found through research it is the point of maximum pressure on the aerofoil. i was wontering what would happen in i was to introduce a secondary thin aerofoil over the top of the original think it is a NACCA 38015. clearance is just a couple of mm. any one...

Except after C! Thank you for your prompt reply, i dont think that it will effect the lift characteristics much i have wind tunnel tested the unmodified NACCA 23015 at low speeds the readings are all roughly the same this was due to a low Reunolds number and scale effect. What the prototype...

Hi would like some info, sorry if it is basic!? what is a stagnation point? where is it located on a NACCA 23015? I am currently doing a project to use the energy at the stagnation point by means of a slat that runs from the leading edge on top of an aerofoil, releasing it at the trailing...

I am currently doing a project to use the energy at the stagnation point by means of a slat that runs from the leading edge on top of an aerofoil, releasing it at the wake region. this in theory should reduce drag, increase lift, greater stall angle, and reduce turbulent flow. Please note I...
