How can you find the natural frequency of an aircraft? It would be of great help if anybody can give me an idea of how to go about the problem.

The natural frequency of what? The fuselage? The wings? The control surfaces? The fuel sloshing about?

This is not a question that can be answered in any satisfactory way on an internet forum. The way you go about solving this problem is to become a mechanical or aeronautics engineer. Along the way you will have to take multiple classes, read multiple books, learn how to use multiple tools.

Hi there,

Finding the natural frequency of an aircraft can be a complex task, as it depends on various factors such as the aircraft's design, materials used, and flight conditions. However, a general approach would be to use mathematical equations and simulations to determine the natural frequency.

One way to start is by studying the aircraft's structural components and their stiffness, which can give an idea of how the aircraft will respond to external forces. Additionally, you can also look into the aircraft's aerodynamics and how it affects its natural frequency.

Another approach is to use finite element analysis (FEA) software, which can simulate the aircraft's behavior under different conditions and provide a more accurate natural frequency value.

I hope this helps. If you have any specific questions, feel free to ask and I'll try my best to assist you. Good luck with your research!
