A technology demonstrator is a prototype aircraft that performs experimental flight tests, modified from a certain variant of a production design. Engineers and scientists often research and experiment with technology demonstrators for ideas of futuristic aircraft. These include new military jetfighter designs, rocket planes and spacecraft. It is important that scientists make sure the aircraft is safe and functions properly before producing it, and testing the technology upgrades is by far the safest way to do it
Scientists of the first half of the 20th century could only dream about today’s supersonic jet fighters. However, thanks to the research these people had done for us has let us obtain this technology. Experimental aircraft were being designed long before World War I and the Wright Brothers, who first reached the air in a plane, performed many tests prior to that amazing accomplishment.
