Project description
There were a lot of constraints in our project. One was all the structural members had to be made out of 1 ½ in ANSI pipe. Another is the structure has to be able to support one Lycoming O-300 engine (250 lb) attached at the three points indicated. Also the frame members have to be mitered. The structure has to be loaded with -3G and 6G which is simulated by exaggerated engine weight due to sudden aircraft acceleration or a change in altitude. The aircraft firewall must be grounded as the stable part of the frame. Also use fixed constraints on the seven firewall to structural member attachment points. Lastly All the pipes have to be trimmed to the face of the aircraft firewall and engine attachment points.
Procedure
To prepare for this project we did two inventor tutorial projects. The first project helped us with the Skeletal model. The second project helped show us how to use the testing environment.
I designed the engine mount first by inserting the frame design then changing the structural member guides to pipes. I then mitered the joints of the pipes together so they weren't going through each other. After that I trimmed the pipes to the face of the aircraft firewall and engine attachment points. Lastly I checked to make sure everything was done and I didn't mess up.

Solution
iI have tested the frame generator against -3G and 6G to see if it would be able to withstand the force and still be good to use.
My design meets the constraints because I used fixed pins, 1 1/2 ANSI pipe, loaded it with -3G and 6G, and I used miters and trims.
The material I used was Stainless Steel Austenitic because it is very strong and has a good strength to weight ratio.

Conclusion
I learned that by using 3D design software you can create things and test them out against different forces.
I believed that the frame generator is very useful in helping aerospace engineers figure out what material is the best for that frame; what can endure the most force.
