MegAWES Circular or Eliptical path

[omidhe89]

I was trying to implement a circular or elliptical path in MegAWES and trying my chance by changing lemniscate parameters such as a_booth and b_booth to different values, but nothing changed in the first traction phase, and the flight got unstable at the early steps of the first retraction phase.
I thought that the lemniscate parameters determine the reference trajectory on the unit sphere, and changing those parameters leads to a new maneuver similar to the reference trajectory on the unit sphere. So, Would you please guide me on why the first traction phase is independent of lemniscate parameters and how I can implement a circular or elliptical path in the MegAWES?

Hi Omid,

Unfortunately, flying circles or spheres is not implemented in MegAWES.
In January a MSc student will collaborate with me to implement this properly in the simulation framework.

The parameters a_booth and b_booth change the figure of 8 roundness(height) and width, respectively.
They cannot be adjusted to form a circle, it will always be a figure of 8 path.

I am not fully sure what you mean with first traction phase? The simulation is initialised by flying a semi-circular horizontal path to stabilise the tether reeling and flight controller. Then it steers towards the first figure of 8 and continues the traction phase by reeling out. There are transition figure of eights but they mainly apply to the location (elevation) much more than the actual shape. This is decided by the a and b parameters and do change the shape when you change them.

Sincerely,

Dylan
