In this article, I want to talk about the inspirational experiment of BBC Earth.
An owl is one of the few birds that can fly silently.
How does an owl fly so silently?
There are a few reasons why owls can fly silently. Their feathers are soft and have a lot of downy fuzz on them, which helps to muffle the sound of their wings. Owls also have a serrated edge on their wings, which helps to break up the sound of the air as it passes over the wings.
But the most important reason why owls can fly silently is that they fly slowly. An owl can fly as slowly as 10 miles per hour and still stay in the air. This slow flight speed allows them to avoid making any noise as they fly.
Owls use their silent flight to their advantage when hunting. They can fly up to their prey without making any noise, and then they can swoop down and catch it unawares.
Owls are not the only birds that can fly silently. Other birds that can do this include falcons, hawks, and vultures.
Check out their incredible experiment:
What can we learn from this experiment?
Beginner training models are always expected to fly slowly. But the quiet flight of these models is very important. Loud flying models can make the training process difficult by worrying the inexperienced pilot. It also makes it impossible for these models to be flown anywhere like a Park Flyer. If we can make our 3D Printed training models as quiet as an owl, we will prevent the models from being intimidating. In this way, more people begin to be willing to fly model airplanes.
To make our models quiet, of course, we have to lower the wing loading. We can achieve this by reducing the weight and increasing the wing area. We can also try to make the Trailing Edge serrated, so it can be tried to break the vibrations created by the wing. Also, larger propellers support low-speed flying with lower KV motors.
This type of model can be used in air missions requiring stealth. They will be unnoticeable, especially at high altitudes. It’s also increasing the training comfort of beginner pilots.
Maybe we don’t create a hunter that can approach its prey silently, but we can develop a model with features that will make an important contribution to our hobby.
