Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the category?Aircraft propelled exclusively by human muscular effort
2. What is the notable scientists/engineers involved?Paul B. MacCready, Derek Piggott
3. What is a human-powered aircraft?A human-powered aircraft is a plane that flies using only the power a person can pedal, like a bicycle. It is built to be very light and aerodynamic so the human can lift and move it through the air.
4. How do pilots make a human-powered aircraft fly?The pilot pedals a drivetrain that turns a big propeller. The propeller pushes air backward, creating thrust that lifts the lightweight wings into the sky.

Aspect Ratio: The ratio of an aircraft's wingspan squared to its wing area, indicating how long and narrow the wings are.
Induced Drag: A type of aerodynamic drag generated as a byproduct of lift, particularly significant at lower speeds and higher aspect ratios.
Biomechanical Efficiency: The effectiveness with which human muscles convert metabolic energy into mechanical work for propulsion.
