# Aerospace Engineeering Experiments

• moust
In summary, the conversation is about someone asking for help with two experiments: one on boundary layers on a flat surface and the other on pressure distribution on an airfoil at different angles of attack. The person also asks for specific questions and mentions using resources such as textbooks, Wikipedia, and Google.

Hi people, i am really in a deep trouble and i will be so happy if anyone can help. Any tips will be so appreciated and make a real different to what i am going through at the moment. i have got two question to answer.

1. Experiment of boundry layer on a flat surface : giving dtails of how the boundry layer are formed

2.Eperiment of pressure distribution on an airfoil at differents angle of attack

So tell us what you know so far, and ask us specific questions if you are stuck on something. What learning resources have you used so far? Textbook, wikipedia.org, google?

Hello, I am an aerospace engineer and I would be happy to help with your questions.
1. The boundary layer on a flat surface is formed due to the interaction between the surface and the surrounding fluid, such as air. As the fluid flows over the surface, it experiences friction and viscosity, causing a thin layer of fluid to slow down and adhere to the surface. This layer is called the boundary layer and it can vary in thickness depending on the speed of the fluid and the roughness of the surface. The boundary layer plays an important role in determining the aerodynamic characteristics of an aircraft or other objects in motion. To study the boundary layer, experiments can be conducted using different techniques such as hot wire anemometry, pressure sensors, or flow visualization methods.

2. The experiment of pressure distribution on an airfoil at different angles of attack involves measuring the pressure distribution over the surface of an airfoil at various angles of attack, which is the angle between the airfoil and the direction of the incoming airflow. This experiment helps in understanding how the lift and drag forces on an airfoil change with different angles of attack. The data collected from this experiment can be used to optimize the design of airfoils for better aerodynamic performance. Techniques such as pressure taps, pressure transducers, or pressure-sensitive paint can be used to measure the pressure distribution on the airfoil surface. I hope this helps and good luck with your experiments.
