I'm trying to design a speed brake that will go on the bottom of a fuselage. It is for a senior design class i'm in. I know the area and shape I need but I'm interested in how to create the hinge point between the door and the aircraft.. I've seen lots of pictures of how it should look on the outside. i.e F-86 Sabre but I'm looking more for the internal servo and hinge point mount. If anyone has any pictures or can direct me to a website with some pictures I'd greatly appreciate it. Having never designed the internal part i'm kinda stuck.
