Looking for a good con job? ... Unlike conventional rocket engines, which feature a bell nozzle that constricts expanding gasses, the basic aerospike shape is that of a bell turned inside out and upside down. When the reconfigured bell is "unwrapped" and laid flat, it is called a linear aerospike.
The linear aerospike features a series of small combustion chambers along the unwrapped bell, also called the ramp, that shoot hot gases along the ramp's outside surface to produce thrust along the length of the ramp, hence the name "linear aerospike."
These technopriests are getting more outrageous all the time. Usually they only talk this trash in private conferences when the tape decks are off.
A bell "inside out" is upside down if you turn it upside down it is now where it started... but inside out which is what occurs to a figuire with plane symmetry when so manipulated. What the hell unwraped means is anybodies guess. If you " flatten" it you get a plate which is what the dummy should have said in the first place! What they are trying to say is a flat plate with a large number of tiny rocket combustion chasmbers drilled into a flat plate instead of one combustion chamber.
The only advantage is that the plate is accelerated not only as in opposition to the reaction mass of the rockets but also the ambient air which would also be acellerated if the exhaust blew across the plate. This effect only works in an atmosphere with an efficiency that probably doesn't compare with a simple ram jet.It's a ram jet turned inside out, only a ram jet doesn't carry its own oxidizer, it breathes.
According to the Hitler principle, a government agency can't afford to give you what its set up to give you because they will loose their job.

One theory is that one of the dominant species to have developed on earth in the last 128 million years is living on the moon & doesn't want to give up the property at this time. The moon's density is only 60% of the density of the other 'solid' planets & asteroids leading to the conclusion that it might be hollow. Fancy that.
