Hello Sir,
Can this BPM engine is good choice for low range sam missile?

I have a question about the swirl injectors: How did you choose their size?
For example, are they of a certain optimal size and scaling them would be bad/inefficient? Or are they the optimal size for the BPM-100? Or are those the biggest ones you can test in the BPM-5?
I mean that’s a lot of injectors, and having fewer parts seems like a good idea to reduce cost and reliability.

Second question: Do you expect a change in efficiency and/or trust when testing them in the BPM-5 compared to the original version, e.g. due to changes in massflow?

    Injectors are due to provide fluid atomization. There are a few books used to evaluate and design. Ones I should suggest are: Modern Engineering for Design of Liquid Propellant Rocket Engines (Huzel), Theory and Practice of Swirl Atomizers.
