Yes you are correct but what about stretching of spring at the time of depostion.The sublimation will be cancelled out due to deposition but at the same time spring is being stretched so if spring compress again after 3 seconds then it must push the craft. Sublimation=deposition+stretching the springButCompression of spring??
I am interested in compression of spring.
@TwarkDear Sir, You are forgetting that ejection of vapor to push the craft forward but at that time the vapor is getting deposited on the surface of plate or the forward force is being cancelled out due to stretching of spring or stretching of spring is already pulling back the craft.So net force is 0.But when spring will compressed again after 3 second then the compression will create thrust to push the craft. What you are suggesting is already cancelled out but compression of spring will be not cancel out and it will work as a thrust.If spring doesn't compress again then net force is 0 but if it is compressing then there is thrustEjection=stretching of springCompression =thrustIf compression of spring will work to pull the craft then how will you define third law??
[an idea]
Dear sir,Can you please explain that why spring is irrelevant in this mechanism if i stretch the spring with a fireball and spring again get its initial position, pushing the craft?I did bathtub experiment using some rubber bands but results showed me feasibility.
So you mean it is a closed system and there is no momentum.You mean spring will be not stretched in this mechanism if the camphor jet hit the plate connected with spring. Is it correct?
Dear sir,Can you please explain that why spring is irrelevant in this mechanism
I just thought about "SUBLIMATION METHOD" for deep space propulsion.As per sketch if camphor solid heated then the vapor will be ejected and a thrust will be created to propell the craft.The camphor vapor will be again deposited on a surface to reuse again and again.The deposited camphor can be reused several time and it is technically possible.Now my question is that should this method will work to propel the spacecraft without spring??Second if it doesn't work without a spring and if i use a spring then should it work as the deposited camphor will work to stretch the spring after each 3 second(the vapor will be ejected after each 3 seconds) and the spring will again compressed, pushing the craft.
