Lecture on the V1 Flying Bomb

Introduction

• Presenter: Kevin Kenz
• Location: Air Zoo
• Topic: In-depth look at the V1 flying bomb
• Structure: Two main components of the V1
  • Fuselage from nose to tail
  • Engine at the rear

Fuselage Breakdown

Nose to Tail Systems

• Air Log (Spinner):
  • Measures the distance flown
  • Connected to a device called a counter unit (Veeder counter)
  • Triggers events based on distance

Counter Unit

• Located at the rear of the V1
• Contains five dials that initiate events when reaching zeros

Key Functions of the Air Log

1. Arming the Bomb
   • Arms two fuses on top of the bomb after 35-40 miles
2. Terminal Dive Initiation
   • Triggers V1 to dive into the target area upon reaching set target distance
3. Radio Transmitter Activation
   • If equipped, turns on radio 30-40 miles before terminal dive

Impact and Navigation Systems

• Impact Switch: Activates fuses upon ground impact
• Magnetic Compass:
  • Encased in a wooden sphere for minimal metal interference
  • Keeps V1 on course, working with the master gyro to correct deviations

Bomb

• Standard load: 1,800 pounds of amytol explosive
• Alternative explosives used based on availability or mission needs
• Fuses and Switches:
  • Front impact switch
  • Belly switch for detonation if landing occurs on its belly

Fuel System

• Original tank: 160 gallons, later increased for longer range
• Fuels: Regular gas, not aviation grade
• Larger tanks developed for extended reach

Air Tanks

• Two tightly wound metal spheres
• Front tank pressurizes fuel
• Rear tank operates gyro and rudder elevator servos

Internal Components

• Battery: 30-volt, powers fuses and radio
• Counter Unit: Manages distance and event sequences
• Gyro Units:
  • Master gyro
  • Two secondary gyros for control surface maneuvering
  • Altitude control device

Pulse Jet Engine

Overview

• Engine type: Argus AS109-014 pulse jet engine
• Produces 660 pounds of thrust
• Known for the distinctive "buzz" sound

Functionality

• Air Valve System:
  • Located at the front with fuel jets
  • Shutters allow air in, close on detonation to direct force backward
• Cycle:
  • 50 explosions per second create thrust (pulse effect)
• Starting:
  • Requires external start cart with air and ignition to start

Launch and Operation

• Launch System:
  • Similar to aircraft carrier catapult
  • Launch speed: 200 mph
• Flight Controls:
  • Pitot tube regulates speed
  • Barometric pressure capsule adjusts fuel for altitude

Performance

• Max speed: 415 mph
• Engine efficiency decreases over time due to wear

Conclusion

• Simple yet effective design
• Encouragement to visit the Air Zoo for further exploration
