Hi everyone! this is my first post here and I would like to discuss a concept I have.
If you didnt hear about coanda saucers , the principle is to get as fast and high pressurized air as possible tangentially just above a curved surface, to create a low presure, suction and entrainment of air.
just a small demonstration:
-----
Just as the title says I wonder if it is possible to simply have a steam powered vtol. Eventhough that sounds very unreal it may not bethat way.
The idea is about building a so called a "coanda effect" flying craft.
I have seen all those toys/prototypes on the net and they are all inefficient.
The advantages over a helicopter are many, no rotors, no huge complexities etc. The huge disadvantage however is how to supply the COMPRESSED AIR EFFICIENTLY! What simply are used today on coanda prototypes are only air impeller-compressers.
The efficieny of the best air compressors to supply the required CFM at the required PSI is very low. So , from there I got the thought of why not just somehow "directly move" the air through the nozzle without "smashing and breaking" the air with the inefficient impellers!
Now I am far from experienced with steam.. but i know that there would be no moving parts and eventhough they can be heavy, they could be worth it.
Why about a steam boiler and a steam ejecter that ejects the superheated steam jet above the curved surface?
The million dollar question is and the main purpose of the thread is to see if high pressurized steam can be produced with less power and less weight than with air compressors. After all we need to produce as high pressure and air volume as possible for a given horsepower.
