`Wind tunnel experiments on three-dimensional-printed models revealed that tucked configurations were statically stable, while spread configurations displayed a nonlinear relationship between pitching moment and lift. This nonlinearity allows configurations to be either stable or unstable depending on the lift state, affording a previously under-explored source of flight performance flexibility.`

Principles of Flight Explained for Beginners

Flight depends on four interacting forces: lift, weight, thrust, and drag.

These principles explain how airplanes move through the air and why pilots manage speed and altitude carefully.

Birds, such as the Harris's hawk, alter their wing and tail shapes mid-flight to transition seamlessly between highly maneuverable, aerodynamically unstable states and steady, aerodynamically stable states to navigate narrow obstacles.

Hawk Study Shows Potential Lessons of Bird Flight

Birds have an ability to fly through obstacles by shifting their shape in flight

In 2022, DJI was able to fly one of their drones over Mt. Everest.

Here are some of the physics challenges involved (see comments) 👇

Here's the drone video (2022) recorded at the highest point on Earth!

In 2024 and 2025, DJI drones, specifically the Mavic 3 Pro and Mavic 4 Pro, achieved record-setting, high-altitude flights over Mount Everest, capturing 8K footage of the summit at 8,848 meters. These drones, often operated with 8KRAW, showcased remarkable stability in high winds (up to 50 km/h) and thin air.

How a NASA Engineer Discovered a World of Semi Truck Aerodynamics by Accident

What started as a minor bike incident resulted in aerospace engineers applying their knowledge to make 18-wheelers more efficient.

🚚 Apparently, aerospace engineers are now #moonlighting as truck whisperers after one had a bicycle boo-boo. Who knew the path to truck #aerodynamics was paved with scraped knees and misplaced expertise? 😂🚴‍♂️
