Greetings everyone,
First post, but I have been parsing this forum often in the past few weeks of my Aerodynamics class at ERAU and have gotten a lot of good information here and there through various posts--various POH links and User Manual for general data, as well as reading through some of your seasoned pilot comments! I am currently working on a group project where we selected the PA-18-150 with the USA 35B airfoil to run our numbers on. I won't ask for too much as I now can tell this aircraft has many configurations--as well as using the search bar! However, when searching for G-force, Load Limits and other limitations--I only seem to turn up weight and balance info (which I will definitely use next week)!
My pointed question has to do with G-force for our week covering "maneuvering performance". I understand that 14 CFR 23 & 25 require civilian aircraft to be designed to meet or exceed specific G force ratings, and those values are listed in a table depicting G numbers for Normal, Utility, Cargo, and Aerobatic. I created a VG table and diagram just going with the "Normal" category force ratings listed in our lecture (+3.8 and -1.5 Gs), but if anyone knows more general "Super Cub" numbers, I would like to tighten up my calculations/charts if able. Being that a cub is a variance of weights, steel tubing/wood/canvas and or a mixture therein--I would guess the rating will vary by configuration and how it is specifically categorized?
Overall, I thank you for your time and any input,
Steve
