Great Success due to Combination of Wright Brothers Airfoil & Newton's Jet !!!

4. Mach Number : A True Measure of High Speed Systems
It is only an economical reason to think that the fastness of an object is described in terms of velocity (km/hr) !!!!
In mentally separating a body from the changeable environment in which it moves, what we really do is to extricate a group of sensations on which our thoughts are fastened and which is of relatively greater stability than the others, from the stream of all our sensations.
Mach number of an aircraft
Mach number of a Jet

Is It Really Possible That The Ancient Indians Had The Capacity To Deploy Devastating Nuclear Weapons Against Their Enemies?
Moreover, Is It Really Possible, As Many Ufologists Claim, That Awesomely Powerful Nuclear Weapons Were Actually Given To The Ancient Indian Warriors By Extra-tererstrials, Highly Advanced Spacemen From Other Planets?
Well, Passages From Ancient Indian National Epics Certainly Appear To Be Evidence Of Such Astonishing Claims….

6. According To The Evidence
“The heavens cried out, the earth bellowed an answer, lightening flashed forth, fire flamed upwards, it rained down death. The brightness vanished, the fire was extinguished. Everyone who was struck by the lightening was turned to ashes”.
And again from the same source: “It was a ghastly sight to see. The corpses of the fallen were so mutilated they no longer looked like human beings. Never before have we seen such an awful weapon, and never before have we heard of such a weapon”.

9. Design of Compact Ramjet - 2

10. Remarks on Ramjets
Control of high speed Ramjet at off design conditions is very difficult due to occurrence of shocks in Nozzle.
Cannot be used for transport of humans and valuables.
Poor fuel economy due to low stagnation pressures.
An artificial method of enhancing/controlling stagnation pressures at the inlet to thrust generator is essential.
