Measurements
OG Design
Original Design
We based the design off of an F-22 Raptor. It didn't have a good enough wingspan to glide very far, and wasn't very balanced. It only traveled a total of 25 cm.
The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft and our idea was to recreate this design as if we were having a stealth plane but without an engine so it would not create any thrust.

Final Box Measurements

Width with wings: 40.605 cm
Height with fin: 19.811 cm
Glue to attach glider parts. We never used any of it though
Cardboard for the wings and fins. We used a decent amount
Duct tape to attach glider parts. We used a whole roll, and a part of another.
Construction paper for the cone, and top cover. we only used two sheets.

The aspect ratio of our glider is our width of glider compared to the length, which is 33.655/14.605 or 2.30434782609
Tail measurements:
Length-12 1/2 cm
Height- 14 1/2 cm
Area- 189 3/8 cm
Designs
There was a total of three designs. The first was the pretty terrible F-22 design, the second added a tailpiece, and on the third there was some confusion on how to make the wingspan bigger, but once we managed to accomplish that in design four, it was okay for gliding.
New Wing Measurements:
Back wing length- 32 cm

Design 2
Added a tailpiece which slightly made it glide slightly better, but made it have too much back weight
Two triangle shaped wings on either side, a fin on top to make more aerodynamic
Added two wings on top of the box to possibly act as a "bigger wingspan," and possibly give it more front weight. We added these instead of new wings since the old ones are very much duct taped on the box
Put two rectangular wings on top of our regular wings (after taking triangle wings off the top) to glide better, and have a bigger wingspan, we then took off the tail because it had too much back weight. After that we put a lot of duct tape on the front to add weight, as well as more fins top and it worked as our winning design.
Total of 8 Trials
Trial 1: Fail, went 25 cm, The box had too much mass and the wings did not have enough lift. We added decided to add a tailpiece to help keep it steady and create lift. https://onslowcountyschools-my.sharepoint.com/:v:/g/personal/12254279_student_onslow_k12_nc_us/EfGaF_Auj8JGnC7dmvRxaboBCxf7zZ1viKlejZ6-3ZF99g?e=nTzebR
Trial 2: Fail, traveled 40 cm, Had too much mass and still did not have lift. We added duct tape to stabilize the wings. https://onslowcountyschools-my.sharepoint.com/:v:/g/personal/12254279_student_onslow_k12_nc_us/EbjAZ0i1lVFOtdZnunDTLLoBeeC50lTvutXs_0VHVJge5g?e=HzqJjf
Trial 3: Fail, went 120 cm, It had lift but still had to much mass in the back. We removed some duct tape to make it lighter- https://onslowcountyschools-my.sharepoint.com/:v:/g/personal/12254279_student_onslow_k12_nc_us/EaqxLyMScalKsPJJeda7ivQBD12R9xUkdqiCK2NcWUi6eg?e=aHMIJt
Trial 4: Fail, went -10 cm, The glider immediately dropped and did not build any lift, We added wings on the top of the box for the next trial - https://onslowcountyschools-my.sharepoint.com/:v:/g/personal/12254279_student_onslow_k12_nc_us/EZtOY_IJsERHuSbQ8dVh0HoBQo6vDAmV0aQEMJuQ4-qkgg?e=cVafos
Trial 5: Fail, went 67 cm, It built lift but didn't go very far and it was unbalanced, We decided to make a new wing design and test them in the next trial. - https://onslowcountyschools-my.sharepoint.com/:v:/g/personal/12254279_student_onslow_k12_nc_us/EeqSnubtYnVIubQjmW_bffABVgXfQM4uIatdcWBceYRZiw?e=OGKz1T
Trial 6: Fail went 130 cm, It had too much mass in the back and flipped backwards, The tail was also damaged, we decided to remove the tail and add more surface area to the front by adding fins- https://onslowcountyschools-my.sharepoint.com/:v:/g/personal/12254279_student_onslow_k12_nc_us/ESqol-drxBdDkhQnifLZs-cBqoNAJPTHjqQO-L_1s347pg?e=ydKux8
Trial 7: Fail, went 139 cm, It still flipped backwards. We decided to add more duct tape to the fins to make it more aerodynamic - https://onslowcountyschools-my.sharepoint.com/:v:/g/personal/12254279_student_onslow_k12_nc_us/ETd3wtMm12ZHv87Mm8cWXc0B9KrLfOpjAn9CgkxsE5B4DA?e=8tuMY7
Trial 8: Partial success, went 269 cm and the left wing was over the 3 meter mark, We'll let Mrs. Corbell decide if Aaron added thrust or not. - https://onslowcountyschools-my.sharepoint.com/:v:/g/personal/12254279_student_onslow_k12_nc_us/ERrJGwDbr5xBvgbI53K_Bf0BAaWZ5-KVvWdXO646amVmxQ?e=BMYxQI
