Growth in business and a countries GDP is often directly proportional to growth in air passenger traffic.
Domestic air passenger traffic in India grew by 21.6% in 2015-16 over 2014-15. So things must be going well!
This was probably the last thing the Wright Brothers envisaged when they made their first flight at Kitty Hawk in December 1903.
The basis of flight being an extension of the principle first framed by Daniel Bernoulli (1700-1782) – velocity/pressure.
The Brothers used carefully cambered surfaces to create better lift – cambered profiles providing better results than flat surfaces.
The cambering principles were first discussed scientifically by Sir George Cayley (1773–1857) a prolific British engineer.
The cambering principles were first set out in 1799 by Sir George,who later discovered the four key forces acting on a heavier than air flying vehicle – weight, lift, drag and thrust.
P.A.Hilton’s F100 range of nine modular experiments allows students to study the key principles effecting early flight such as Bernoulli’s principle, pressure, boundary layers, velocity, drag, flow visualization etc.
Whilst engines of differing types were fitted to flying machines almost from day one, it wasn’t until Sir Frank Whittle (1907-1996) patented the first jet engine in 1930 that our world suddenly shrank.
The high level principles of jet engine technology are easy enough to understand. Compress air and mix with fuel, ignite, allow hot gases to expand and release energy.
However, the reality of building these devices is far from simple.
The P.A.Hilton F300 range allows students to study the principles of compressible fluids.
The F300 range of seven modular experiments covers key learning areas such as nozzle performance, pressure distribution, turbines, friction etc.
But the heart of the jet engine is its combustion chamber. Studying all aspects of combustion is key to the longevity and future development of these power units.
The P.A.Hilton C492 units affords the students the opportunity to study combustion efficiency, heat transfer and energy balances.
The C492 is used by many University across the globe to teach the principles of combustion and in some cases being used to conduct research. http://www.mdpi.com/2071-1050/5/5/2098
Studying engine performance is key to the development of future power units. Environmental concerns relating to noise and air pollution have helped shape current and future engine designs, as well as increases in better power to weight ratios etc.
A full understanding of how engines perform to a set of pre-prescribed conditions is essential if the student is to fully understand this topic.
P.A.Hilton’s P372 Jet Propulsion Test stand offers the student a complete performance analysis at various approach speeds. Calculation of exhaust velocities, measurement of temperatures, thrust, specific thrust, drag and fuel consumption.
This unit ships complete with both ramjet and pulse jet.
