Good to hear that u also feel it will have double thrust coz thats what i need.
But if we think more precisely, I dont think so.
lets use certain assumptions and an example,
let each motor is pushing air at the speed of 'x' Km\hr.
so in fig 1. arrangement,
1. M1 pushes air at speed of x km/hr.
2. M2 will also try to push the air at speed of x km\hr, however the air reaching at M2 is already at the speed of x Km\hr, so how the speed of air will increase (thereby increasing thrust) coz I dont think we can just add the thrust.
However in fig.2 the air is beign pushed at x km\hr at two points, so theres a possibility of double thrust.
But I want to use fig. 1 but don't know whether my assumption above is right or wrong.
I want it to be wrong..
