I'm afraid that I don't know what those terms mean.
From a pilot's perspective, I'd look into whatever the German 'Stork' aeroplane used. That's the slowest thing that I've ever seen in my life. I'm old and have emphysema and arthritis, but I can probably still run faster than its take-off speed. I once saw one flying backward over a runway because it had a 20mph headwind.

Danger said:I haven't heard that before, but I wouldn't doubt it. With any kind of decent headwind, it was capable of VTOL performance.
Good catch, Dave. :rofl:
A low speed aerfoil is a type of airfoil or wing section that is designed to provide the most lift at low speeds, typically below 200 miles per hour. These types of aerfoils are commonly used in aircraft that fly at lower speeds such as gliders, agricultural planes, and some small recreational aircraft.
Choosing a low speed aerfoil is important because it allows an aircraft to generate enough lift at lower speeds to take off and maintain flight. This is especially important for aircraft that operate at low speeds or have a high wing loading, which is the weight of the aircraft divided by the surface area of the wing.
One of the main benefits of using a low speed aerfoil is that it allows an aircraft to take off and land at lower speeds, making it safer and more maneuverable in certain situations. It also allows for better control and stability at low speeds, which is important for aircraft that fly at low altitudes or in turbulent conditions.
Choosing the right low speed aerfoil for a specific aircraft depends on several factors, including the aircraft's weight, wing loading, and intended use. It also involves analyzing the aerodynamic properties of different aerfoils and selecting the one that will provide the most lift and stability at the desired speed range.
One potential disadvantage of using a low speed aerfoil is that it may not provide enough lift at high speeds, limiting the maximum speed of the aircraft. Additionally, some low speed aerfoils may be less efficient and produce more drag than other aerfoils at higher speeds. However, these disadvantages are often outweighed by the benefits of using a low speed aerfoil for the intended purpose of the aircraft.
