Questions and Answers

What are three applications of drones?

Defence and military use, photography and videography, transportation of goods.

Describe the role of lift in drone aerodynamics.

Lift pushes the drone upwards, allowing it to ascend and maintain altitude.

List the four forces acting on a drone during flight.

Lift, thrust, gravity (weight), and drag.

Explain Bernoulli's principle in relation to drone flight.

<p>Bernoulli's principle states that faster air above the wing creates low pressure, leading to lift.</p> Signup and view all the answers

Name two types of drones and describe their differences.

<p>Fixed-wing drones and multi-rotor drones; fixed-wing drones have wings and are more efficient in long flights, while multi-rotor drones can hover and maneuver easily.</p> Signup and view all the answers

Flashcards

Thrust

The force that propels a drone forward. Think of it like the engine pushing the drone ahead.

Gravity (weight)

The force that pulls a drone downwards due to gravity. It's the weight of the drone.

Drag

The force that opposes thrust and pushes the drone backwards. It's like the resistance of the air against the drone.

Single-rotor Drone

A type of drone that uses a single spinning blade to generate lift. It's similar to a helicopter.

Multi-rotor Drone

A type of drone that uses two or more spinning blades to generate lift It's the most common type of drone.

Study Notes

Drone Applications

Drones are used for defense and military purposes
Drones are used for photography and videography
Drones are used for transporting goods

Forces in Aerodynamics

Lift: Pushes the drone upwards
Thrust: Propels the drone forward
Gravity (Weight): Pulls the drone downwards
Drag: Opposes thrust and pushes the drone backward

Types of Drones

Fixed-wing drones
ITA drones
Multi-rotor drones
Single-rotor drones

Bernoulli's Principle

Bernoulli's principle explains that air speeds up over the curved upper surface of an airfoil
Air has to travel faster over the curved upper surface, thus resulting in lower pressure above the wing
The higher pressure below the wing pushes the drone upwards.
