It is flapping wings.
Yes, dragonflies have wings. They have two pairs of transparent wings that they use to fly by flapping them in a unique pattern. This allows them to maneuver quickly and efficiently in the air.
It is flapping wings.
Bees do not scream but they do buzz and make a vibrating sound. This buzzing or vibration comes from their wings flapping so fast when they are flying.
The area of the wings of a flying machine is determined by the lift required to support the weight of the machine. Factors such as the design of the wings, airspeed, and flight conditions will also play a role in determining the required wing area. In this case, we would need more information to calculate the specific area of the wings required to support a 100 kg flying machine.
that would be the wings, like all flying insects that make a buzzing sound.

By flapping them?
Ornithopter is an aircraft designed to derive its chief support and propulsion from flapping wings, much like a bird.
I bird controls its altitude by flying. It flaps its wings to go up, and stops flapping them to go down. Its simple.
