The History of The Ignitor
Sometime in early-mid 1957 both Orville Carlisle and G.H. Stine developed forms of electrical ignition for model rockets. They both were attempting to further separate model rockets from fireworks. Originally the Carlisle model rocket they used a fuse type ignition. Neither Carlisle or Stine filed for a patent, however there were many earlier patents that hinted at this process. It wasn’t until 1965 that Vernon Estes applied for a patent in which he received in 1968 specifically for model rockets.
But before the ignition starting in the late 1700's, European engineers began tinkering with motor powered vehicles. Steam, combustion, and electrical motors had all been attempted by the mid 1800's. By the 1900's,The combustion engine continually beat out the competition, and the early American automobile pioneers like Ransom E. Olds and Henry Ford built reliable combustion engines, rejecting the ideas of steam or electrical power from the start.
Igniters are based on the method of converting electric energy to heat energy by resisting the free flow of electric current. When the electrical current is applied to a metal conductor it encounters resistance. The resistance is then converted to heat. a common ingredient in igniters is nickel-chromium, or as it is better known, nichrome. Nichrome heats up easily but doesn’t melt. The tips of these type of igniter usually contain a Squib. Squibs are materials that ignite and burn.
The igniter helped the economy because it brought many things in phases in the past like cars.
When was thermodynamics found?
Basic physical notions of heat and temperature were established in the 1600s, and scientists of the time appear to have thought correctly that heat is associated with the motion of microscopic constituents of matter. But in the 1700s it became widely believed that heat was instead a separate fluid-like substance. Experiments by James Joule and others in the 1840s put this in doubt, and finally in the 1850s it became accepted that heat is in fact a form of energy. The relation between heat and energy was important for the development of steam engines, and in 1824 Sadi Carnot had captured some of the ideas of thermodynamics in his discussion of the efficiency of an idealized engine.This also lead to help many science fields like physics and chemistry.
