I know nothing about Boom, but the "high bypass supersonic" thing raises the obvious question, how do they avoid the drag from the large (by definition) cross sectional area of the high-bypass fan?
- bbojan 4y agoI'm not privy to what Boom is doing, but variable intake geometry easily takes care of this.
- snovv_crash 4y agoYou still have the massive frontal area though
- MichaelCollins 4y agoThey actually wanted medium-bypass engines. Low-bypass relative to modern airliner engines, but high-bypass relative to supersonic military turbofans.
