Week 1 Intro To UAS 270, Comprehensive History and Classification of Uncrewed Aircraft Systems (UAS)

Early Foundations of Flight and Autopilot (1903–1918)

• $1903$ First Manned Flight: The Wright Brothers achieved the first successful controlled, powered, crewed flight in $1903$, initiating the modern aviation era and paving the way for both manned and uncrewed aircraft development.

• $1907$ First Quadcopter (Gyroplane No. 1): Invented by brothers Jacques Breguet and Louis Breguet.

  • It represented the first historical attempt at constructing a practical, manned rotary-wing aircraft.

  • Design & Operational Characteristics: The airframe was unsteerable and required $4$ ground handlers to steady it during operation. On its maiden flight, it achieved a vertical lift of $2\text{ feet}$ above the ground.

  • Current Location: The Gyroplane No. 1 is preserved and housed in the Musée des Arts et Métiers, an industrial design museum in Paris.      

    

• $1908$ Sperry Gyrocompass: Elmer Sperry developed the gyrocompass for maritime navigation applications, including naval ships and marine torpedoes.

• $1911$ Development of the Gyro-Control: Elmer Sperry and his son Lawrence Sperry created a lightweight version of the marine gyrocompass called the Gyro-Control. This was a $3\text{-axis}$ mechanical gyroscopic autopilot engineered to enhance flight stability and control.

• $1913$ Aerial Torpedo Application: Lawrence Sperry applied the Gyro-Control to aviation platforms, developing the Sperry Aerial Torpedo, which achieved its initial successful flight in March $1918$.

• $1914$ Public Flight Demonstration: Lawrence Sperry publicly demonstrated the capabilities of the Gyro-Control at the Ligue Nationale Aérienne de France (National Aerial League of France):

  • Pass $1$: Sperry flew past the flight line with his hands removed from the control stick.

  • Pass $2$: Flight engineer Emil Cachin walked out onto the wing while Sperry kept his hands off the controls.

  • Pass $3$: Sperry and Cachin walked out simultaneously onto opposite wings; the Gyro-Control stabilized the asymmetric aerodynamic load automatically.

• $1917$ First Unmanned Aerial Vehicle (UAV): A.M. Low developed the "Aerial Target", a radio-controlled (RC) airplane widely regarded as the first true UAV.

• $1918$ Kettering Aerial Bomb ("The Bug"): Charles Kettering designed an uncrewed aerial bomb known as the Kettering "Bug", utilizing the gyroscopic control concepts pioneered by Sperry.

Interwar Developments and Early Target Drones (1919–1939)

• $1919$–$1939$ Target Drone Programs: Military institutions developed uncrewed target drone platforms derived from early autopilot and radio-command technologies.

• $1920$ Messenger Aerial Torpedo (MAT): Designed as a lightweight, low-cost aircraft intended for aerial messeging, reconnaissance spotting, and artillery fire direction.

• $1922$ Verville-Sperry M-1 Messenger: A full radio-control (RC) command system was integrated into the Verville-Sperry M-1 Messenger MAT platform.

• Origin of the Term "Drone": Between $1919$ and $1939$, the British Royal Air Force (RAF) developed the "Queen" and subsequently the DH.82B "Queen Bee" target drones. The designation "Queen Bee" is considered the etymological origin of the word "drone".

• $1930\text{s}$ Navy Target Drones: The United States Navy Research Lab engineered the N2C-2 target drone.

• $1933$ Reginald Denny and the Dennyplane: Reginald Denny developed the "Dennyplane" RC target drone, pioneering standardized, scalable production for uncrewed target systems.

• $1937$ Hobby Radio Control Advances: Bill Good and Walt Good constructed a vacuum tube-based remote control system for model airplanes, initiating the hobbyist radio-control aviation industry.

• $1939$ First Practical Helicopter (VS-300): Igor Sikorsky designed and flew the VS-300 experimental single-rotor helicopter. Its initial tethered flights took place in $1939$, followed by its first free flight on May $13$, 1940$.\n\n  \n\n# World War II Breakthroughs and Early Assault Drones (1940s)\n\n* **Video Guidance
