Analyzing the Trajectory of a Flying Disc: Factors and Possibilities

[Gonzolo]

Hi,

I'm wondering how difficult it would be to exactly determines a flying disc's trajectory given it's dimensions, rotation, initial velocity and angle of attack.

Can this be done analytically?

What if the lateral angle is also varied? (freesbie not parallel to ground as viewed by person who throws)

Thanks.

I'm not sure it can be solved analytically. The problem is clearly tridimensional. Pressure variations in trasnversal direction due to the rotation will make the freesbie taking a curved path in a plane xy.

Also, pressure variations in z direction will enhance the lifting force of the freesbie. But in some way it can be simplified supposing the height doesn't vary. And you can simplify the transversal (x,y) movement working out the pressure differences between the inner part and the outer part of the freesbie using Bernoulli if the Reynolds Number is enough larger.

I think that's not a trivial problem at all.

Analyzing the trajectory of a flying disc can be a complex task as there are many factors that can affect its path. However, with the right information and tools, it is possible to determine its trajectory with a high level of accuracy.

To start, the dimensions of the flying disc, including its diameter and weight, will play a role in its flight. The rotation of the disc, which is influenced by the spin imparted on it by the thrower, will also have an impact on its trajectory. Additionally, the initial velocity and angle of attack, or the angle at which the disc is launched, will greatly affect its path.

Determining the trajectory of a flying disc can be done analytically, using mathematical equations and principles such as projectile motion and aerodynamics. This method requires precise measurements of the disc's dimensions and initial conditions, as well as a thorough understanding of the physics involved in its flight.

However, if the lateral angle, or the angle at which the disc is tilted relative to the ground, is also varied, the analysis becomes more complex. This is because the lateral angle can greatly affect the lift and drag forces acting on the disc, which in turn will alter its trajectory. In this case, computer simulations or experimental testing may be necessary to accurately determine the disc's path.

In conclusion, while analyzing the trajectory of a flying disc may be challenging, it is possible to do so with the right information and techniques. By considering factors such as dimensions, rotation, initial conditions, and lateral angle, the trajectory of a flying disc can be accurately predicted.
