How Do You Calculate Static Pressure on Hypersonic Vehicles?

AI Thread Summary
To find the static pressure on a hypersonic vehicle's surface, use the oblique shock relations, which are sufficient given the straight sections of the body. Knowing the inclination angle of the surface and the aerodynamic characteristics of stage 1 is crucial. With a calorically perfect gas assumption (gamma=1.4), you can derive static pressure from the incoming angle of attack and Mach number. The distinction between static pressure and stagnation pressure is important, but the oblique shock equations will provide the necessary information. This approach will yield accurate results for the static pressure on the vehicle's surface.

I'm confused about finding the static pressure on a surface of a hypersonic vehicle.

I know the inclination angle of surface 1 relative to the horizontal and I know all the aerodynamic characteristics of stage 1. With a calorically perfect gas assumption, gamma=1.4. I'm getting a little confused with static pressure and stagnation pressure. What is the appropriate equation to use?

Just use the oblique shock relations. On the body you have pictured you have straight sections, so you don't need anything more complicated. If you know the incoming angle of attack and Mach number, you can generate all the information you need for static pressure using the oblique shock equations.
 
Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
