Nature’s Remarkable Small Flyers The Bumblebee (weight = 0.002 - 0.02 oz) • Enormously maneuverable system
• Horizontal thrust >5x its weight • Payload = 100% body weight (nectar) • Holds image velocity of landing surface constant on approach (zero velocity at touchdown)
The Dragonfly (> 300M years old; weight = 0.01 oz)
• Flies at speeds up to 30-60 mph • Wings work independently – can hover and change direction instantaneously • Short wing strokes + unsteady-state airflow allow forward & backward flight at hover while horizontal • Voracious appetite – seeks and eats insects on the fly
The Hummingbird (weight = 0.1 oz)
• Only bird that can hover with body motionless – but requires excessive energy to sustain • Consumes ½its weight in sugar daily from nectar • Generates thrust from both down beat & up beat – wings perform a figure 8 in hover • Endurance: 800 km migration across Gulf of Mexico at 40 kms/hr for 20 hrs without stopping
The Army… Transforming while at War “…we must achieve: fundamentally joint, network-centric, distributed forces capable of rapid decision superiority and massed effects across the battlespace.”
“Finally, the nature of expeditionary operations argues for leveraging every potential tool of speed, operational reach, and precision.” Serving A Nation at War
