aery glider final design
following the previous design testing to be affiliated with the AERY design software, a custom design was produced. This one would be cut on a laser printer and this the following changes to the type of wood used were implemented. Note that this would change the max fuselage length and other various maximums for the design:
The plane was then designed. Specs and plane image is below:
All parts were then designed in Autodesk inventor, both as part flies (.ipt) and drawing files (.idw). The Plane was then assembled as an assembly file (.iam). The wings, vertical stabilizer, and horizontal stabilizer were then put into a separate part file and drawing file on a 20 x 3 cm base so as to be prepared for laser cutting. Note that there is a wedge so as to improve in-flight stability. All images below:
construction and real test data
The Plane was then cut on a laser printer and assembled, image of glider below:
Flight data, including distance by tiles number, starting velocity, and pitch/directional stability were measured. If the plane pitched up, more clay was added to the nose. if the plane pitched left, clay was added to the underwing of the right. The distance increased as the plane was pulled back to a father starting velocity. During the final test, the plane was extended to a starting velocity of 45 m/s. The plane traveled 75 tiles distance with only a slight pitch left. Data is below:
conclusion questions
1. The glider did not fly as expected. This could be due to imperfect construction which would lead to altered flight results.
2. Techniques used to trim the glider for more streamlined flight include rearranging the clay on the nose that acted as weight to a more v-shaped, streamlined design to facilitate air flow. another technique used was pressing balancing clay added to under the wings and pressing it in. this created a tighter seal and less interaction between the excess clay and drag.
3. 15 tests were needed to prepare the glider for long-distance flight. This was to be expected as the nose weigth was off and the construction of the plane was not entirely perfect. These test flights allowed the plane to be edited and trimmed into the best and closest design possible.
