It’s that time again!
For those wondering what happened to this thread.....someone forgot to make sure it didn't get archived. ![]() I will try to recreate what was posted in the archived thread. https://www.ar15.com/forums/general/F-22-Raptor-2021-2022-Student-Project-thread-Update-5-21-pg3-sections-cut-and-ready/5-2450198/ For the last nine years?, ARFCOM has been an essential part of the adventure my students' experience with the building of permanent large installation projects here at our high school. I know that this year and next will be no different, and our success will be attributable to the incredible help that so many of you provide. These projects have rejuvenated my teaching style, given students something they love coming to school for, and providing experiences that they truly value. Thank you all, again, for being such a great community. My Art classes will again work with CAD students, Welding students, Woodworking students, and Robotic students to try to create our next display. For those new to our adventures, roughly 60-80 students from grades 9-12 will work the entire school year to build from scratch a permanent 3D display in an area roughly 16’wide x 23'long x 20’high. Some students might only spend an hour working on this, some three weeks, and some might spend several hours every day the entire year. Our last three projects have ended up costing about $2500 each. The generosity in both funds, equipment, and advice in our previous years have made all the difference in being able to spend that much money on such a project. We will again have to have a t-shirt sale to celebrate the adventure and raise the funds needed. The fundraiser will be near the end of the project, so not for almost a year. Now for the important part. Our new subject will be the F-22 Raptor . There are many seniors that are just a little miffed at not being able to see this one through. They had to finish up the Mission To Mars display, cut short by Covid, and then build Liberty Ships to add to the U-boat display. The current display area has our 1/2 scale Sopwith Camel already displayed there. We will be moving it up ant towards the right wall. This will give us enough room for a 15.5' long x 11' wide Raptor. We will also be creating a WWII hanger/airfield scene in the background that will have 3D elements. Maybe a Spitfire coming out of the hanger? The display will be a tribute to evolution of fighter aircraft. I'm sure we will come up with more ideas to add as the display starts to come together. Feel free to share them in this thread. The brainstorming that ARFCOM contributes is one of the most important parts of this adventure. ![]() ![]() ![]() ![]() The display area 16'x23'. If we don't put the Raptor on a knife edge, as was suggested at the end of the Uboat/Liberty ship thread, the students are standing at the outer points of the aircraft at 15.5'long x 11' wide. ![]() ![]() I like the knife edge idea instead of simply inverted. I think we can create a bit more space this way, and allow for detailed internal stores. We want to try to produce the engine mach cones? We think we have an idea for how to do that based on the SpaceX rocket we built last year. We probably will use fiber optic bundles to do some of that. Some of our previous adventures. https://www.ar15.com/forums/general/ALARM-U-Boat-Type-VIIC-2015-Liberty-Ship-Edward-Avila-Update5-4-pg71-ships-up-/5-1781084/ ![]() ![]() ![]() https://www.ar15.com/forums/general/-/5-2247089/?r=-1&page=1 ![]() https://www.ar15.com/forums/General/1-3rd-Scale-17ft-Marine-One-Helicopter-Project-ThreadUpdate-6-17pg54-magazine-article-/5-2133113/ ![]() https://www.ar15.com/forums/general/ALL-ABOARD-1-3rd-scale-Baldwin-4-4-0-Locomotive-Update-5-24pg29-The-End-is-here-Video-/5-2025503/ ![]() ![]() ![]() |

1" is definitely seems too thin for the wing to me. It has been a long time since I was turning wrenches on F-22s, but I remember just the trailing edge of the leading edge flap being around 6" on the inboard side and tapering down to around 4". Leading edge flaps are in the full down position in this picture. https://www.ar15.com/media/mediaFiles/54089/IMG_5032_JPG-1931638.JPG Note the AIM-9 in this picture and compare it to the LEF. AIM-9s are 5" in diameter. https://www.ar15.com/media/mediaFiles/54089/040430-F-0000S-015_jpg-1931639.JPG View Quote Great pictures thank you! Those panel pics are perfect! As to the wing thickness, at 6 and 4", 1/4 scale would end up being what we are seeing in the CAD drawing we have. Tip of wind would be about 1" thick. I believe where the student cut the wing from the fuselage is not what would be called the "root". I think we are on the right track with the scale there. The curve will be the challenge. |

Have you and the team given any thought to making anything articulate on the aircraft? There may be some options to scale available on the RC Jet parts market to incorporate into the project if there is some interest. View Quote That's an excellent question. We have not, but having the weapon bay doors open and close would be pretty amazing. We could copy much of the tech we used on the space shuttle. I'm going to need to discuss this with Robotics and see if they have an ambitious person who would take it on. Thanks for that idea! |

I saw an interesting video a few days ago, where a woman took some clear two part resin, and poured a layer, then she used like a sharpie to draw on it, then she poured a thin layer on top, and drew some more, and so on. The end result was a pretty damn realistic/3d dragon. Maybe yall could do that for the mach cones, or even the canopy if yall cant get the plexiglass to work out. Would be a bit on the heavy side, but its an idea.
Also, loved your previous threads, if the schools I went to did that kind of stuff, it would've made school much better. Can't wait to see the end product. |

Hmmm... just need a way to have the missile travel in a loop; program in a start/stop point under the bay door... |

View Quote I've had good luck heating acrylic (plexiglass) in an oven, and then forming it over a mold - it's really malleable when it is heated up. I used a two part compression mold because the application I had in mind required the final part to be precise; basically a mold with a void in the middle in the shape of the part you want to produce. The tricky part is heating the acrylic: a little too much heat and bubbles form in the acrylic, way too much heat and you have a puddle of acrylic, etc., etc. |

Heres a video I found on youtube that shows it well. ![]() Making Lifelike 3D Aquariums With Paint Cast In Resin As for getting it to travel in a loop, you could probably use a system similar to skylifts or roller coasters, use a thin cable or tubing for the track, and a small motor with two rubber wheels on it to provide motion. But, it may not be the most aesthetically pleasing thing unless you can hide the track from view. Or, if you want to keep it pleasing, don't have it do a loop, but instead just have it drop down, and move it forward. You could use a piece of tubing slightly longer than the length of the missile itself (or even use multiple pieces like a retractable antenna to give more distance), and use that as the track that will provide support for it to move forward, again using a small motor and rubber wheels, or some motion device like magnets, linear actuators, pulley system, etc. Depends on how much math/science you'd want to incorporate. I'll see if I can come up with some more ideas, sounds like a fun challenge to figure out a way to get it to work. |
