Week 7 Update

Physical Work:

The group has begun working on the final models of the gliders—specifically the control (models & modifications can be seen below in Figure 2). The specifications for each model are still to be entirely determined, but the preliminary design can be seen in CAD form in Figure 1.

Statistical Analytical Table (See Figure 2):

            The table seen in Figure 1 (not labeled as a table, as this is simply a picture) outlines the criteria that we will be working with throughout the flight tests as well as the individual modifications. There will be four modifications:

·         Flaps and Ailerons

·         Horizontal Stabilizer Shape & Size

·         Weight Added and Distribution to Model

·         Wing Design

These modifications will be tested against four criteria:

·         Flight Time (in seconds)

·         Distance Traveled (in feet)

·         Deviation from Start Point (in degrees)

·         Ratio of Drop to Distance Traveled (in feet)

Explanation / Justification of Modifications:

1.      Flaps and Ailerons

The addition of flaps and ailerons to the aircraft will be to reduce fluctuations in vertical movement. They address issues of stability and will elongate flight duration.

2.      Horizontal Stabilizer Shape and Size

Modifications made to the horizontal stabilizer will effect (and expectantly improve) vertical movement, stability and flight duration.

3.      Weight Added and Distribution

While testing the various preliminary models and designs, the group has found that the distribution of weight is incredibly vital to any form of aircraft. Much of an aircraft’s functionality is determined by its distribution of weight. Allowing for the added weight and distribution to be a modified factor will provide insight into what sort of distribution would create, for example, a farther-flying aircraft. 

4.      Wing Design

The wing provides most, if not all, of the lift for an aircraft. By changing the design of the wing, the group aims to explore the different effects created by varying the wing’s design. The main purpose of having this modification is to determine what design results in greater lift and less drag, subsequently producing a more aerodynamically efficient model.
