How much do spoilers increase drag coefficient?

AI Thread Summary
The discussion centers on estimating the drag coefficient increase due to spoilers, starting from a baseline of 0.02689. Participants emphasize that while spoilers can be approximated as flat plates, the actual impact varies based on the aircraft design. Suggestions for further research include consulting resources like books, AIAA journal papers, and NASA technical documents. One participant recommends Raymer's book as a potential source for modeling insights. The conversation highlights the need for accurate data to enhance braking system models in aviation.

Approximetly how much is the drag coefficient if orginally the coefficient is 0.02689. I know it depends on aircraft etc but I am only looking a rough estimate.
 
Physics news on Phys.org
As a first order guess, spoilers are a flat plate. But, what outside sources have you consulted?

what do you mean by outside sources?
 
Books, AIAA journal papers, NASA technical server, etc. What exactly are you trying to model here?
 
i am modelling the braking system. so i need to know how much drag the spoilers provide to enhance my model
 
Have you tried Raymers book?
 
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/
