Soaring: Maintaining free flight without power, usually in a thermal current of ascending air.
Solidity: The ratio of the blade area of a propeller or rotor to the total disc area.
Slope Soaring
In the simplest terms it is flying a glider in the updraft created by the wind blowing on-shore and up a cliff.

Soaring is the art of using air currents to stay airborne. In order to keep a sailplane aloft and maintain control, you must be able to handle several tasks simultaneously.
Soaring fuel prices have continually intensified the airline industry's efforts to increase fuel efficiency - the most effective means of reducing emissions.
Who hasn't imagined soaring free like a bird? Learning to fly is a goal held by many people. Even people who have grown up in areas of the world not blessed with general aviation (GA), have spontaneous dreams of flight while sleeping.
After many years of experiment and study of soaring birds he constructed rigid wings which he held to his shoulders and which, after he had gained considerable velocity by running forward downhill, ...
Building a giant radio controlled aircraft can send your spirits soaring. RC aircraft come in many different sizes and can be constructed from many different materials. Many hobbyist build RC aircraft from kits.
The collection included excerpts from Louis-Pierre Mouillard's Empire of the Air; Langley's own The Story of Experiments in Mechanical Flight; Otto Lilienthal's The Problem of Flying and Practical Experiments in Soaring; and E. C.
This is the CN Tower in Toronto, the world's tallest free-standing structure, soaring 1815 feet high. Obviously, it's the place to be for views of Toronto.
GLIDER - A heavier-than-air, fixed wing, unpowered aircraft for gliding or soaring flight.
HARDPOINT - A strengthened section of the under-wing or fuselage, intended for the carriage of external weapons or stores, usually on pylons.
SAILPLANE - An unpowered, soaring aircraft capable of maintaining level flight for long periods of time after release from tow and of gaining altitude using wind currents, as opposed to a GLIDER.
In point of fact, as already intimated, those who have succeeded in the air, the true experts in gliding, the soaring birds, do not perform their evolutions with plane surfaces.
However, with the advent of World War I, the military value of aircraft was quickly recognized and production increased significantly to meet the soaring demand for planes from governments on both sides of the Atlantic.
- to set the angle of CS or VP propeller edge on to the airflow to minimise drag and rotation following engine failure on multi engined aircraft. Also applies to motor gliders which have feathering propellers to enhance engine off soaring ...
Short wings are also stronger than long wings. Gliders use high-aspect ratio wings (long, skinny wings) because they are more efficient for soaring flight. Example: 10 ft. wingspan with a 1 ft. chord has an aspect ratio of 10.
