    lift equations

    Hi, A good way to do it is to use a CFD program. here are the steps you need to do for that type of simalation. 1) You design your blade cross section. 2) You find the air density and characteristics at the maximum altitude you plan to reach. 3) Calculate your lowest airflow at the blade...

    Tip Jet helicopters

    Hi Bob, As for your interogations about the intake stack of a pressure jet, trust me, it works fine. The stack work under 3 concept at once. 1) As a series of ejectors 2) A series of resonant tubes coupled together to maximize air pumping 3) The 3rd stage inlet tube is a diffuser and as...

    Tip Jet helicopters

    Hi, Yeap ... Maybe. But then, when those RAM jets get to higher speed, the flame holders can not slow down the air below flame propagation speed and you end-up blowing your flame front out. And they sure can not acheive supersonic speed. Also, these slow speed RAM jets are very sensitive...

    Tip Jet helicopters

    Hi lightweight, First, the German V1 Bomb did not use a RAM jet, but an Argus Pulse jet. Using RAM jet is not something you will often see unless you can find a user that can accelerate this engine above the 400 Mph mark. Before that speed, I don't beleive you will see a RAM jet operate or...

    Tip Jet helicopters

    Hi again, Wrong again ... The pressure jet is a fully autonomous jet engine and require no assistance or blade forward mouvement to start. Only the pulse jet does. The pressure jet is exactly like a gas turbine, without the moving parts. Ignition ON and fuel ON and this thing is gone...

    Tip Jet helicopters

    Hi Bob, Wrong ... Very wrong. Well ... It depend. If you want to do like I did years ago and waist $3,200.00 USD on a pressure jet that was not even delivering 50% of its rated thrust ... Vortech is the best place to buy. Also, you need to know that since June of this year, my partner...
