Study Notes

A Brief History of Aircraft Reciprocating Engine

Efficient propulsion systems have historically limited aircraft development.
Leonardo da Vinci invented the "aerial screw" in 1483, but it was never realized due to a lack of practical propulsion.
Da Vinci's design inspiration came from the rotation of maple seeds and Archimedes' screw.

Leonardo da Vinci

Italian polymath of the High Renaissance, known for iconic art, engineering, and scientific notes.
Renowned artworks include "Mona Lisa" and "The Last Supper," with the latter being the most reproduced religious painting.
Da Vinci's notebooks cover diverse subjects, influencing future generations of artists and inventors.
Many of da Vinci's machines, including the aerial screw, were sketched but not built during his lifetime.

Aerial Screw Design

Da Vinci's drawing from the late 1400s detailed a device intended to be powered by four men, pushing shafts in a circular motion.
Intended materials (reed, linen, wire) would make the device too heavy for flight.
Basic principles of lift in the aerial screw laid groundwork for modern helicopter flight.

Development of Piston Engines

John Barber patented the first heat engine in 1791, but it lacked efficiency.
Étienne Lenoir built the first practical piston engine in 1860 using battery ignition and natural gas for industrial machinery.
Dr. August Otto developed the four-stroke, five-event cycle in 1876, which is the basis for modern reciprocating engines.

Key Figures

John Barber (1734–1793): English inventor, known for his early work in heat engines.
Étienne Lenoir: Innovator of practical piston engines that advanced the use of gas in machinery.
Dr. August Otto: Pioneer of the four-stroke engine cycle, crucial for modern aircraft engines.
