wing loading
Học thuậtThân thiện
Definition
Noun: - Aerodynamic Measurement: The ratio of the total weight of an aircraft (or other flying object) to the total area of its wings. It is a key parameter in aircraft design and performance, influencing factors like stall speed, maneuverability, and takeoff/landing distance.
Usage
Wing loading is a critical specification in aviation and aeronautical engineering. - The glider's low wing loading allows it to stay aloft in very light thermals. - High-performance fighter jets typically have a very high wing loading.
Advanced Usage
- Comparative Analysis: Wing loading is often used to compare the design and intended flight characteristics of different aircraft. A lower value generally indicates better performance at low speeds and greater lift efficiency.
- In Bird Flight: The concept is also applied in ornithology and the study of animal flight to compare the flight mechanics of different bird species.
- Formula Context: It is calculated as: Wing Loading = Aircraft Weight / Wing Area. The weight is usually the maximum takeoff weight.
Variants and Related Words
- Loaded Wing: A term sometimes used in technical discussions to describe a wing under aerodynamic load, but this is not a direct variant of "wing loading."
- Span Loading: A related but distinct aerodynamic measure focusing on weight distribution relative to wingspan.
Synonyms
- Aircraft weight-to-wing-area ratio: A descriptive synonym.
- Wing area loading: A less common alternative phrasing.
Related Phrases
- High wing loading: Describes an aircraft design where the weight is high relative to the wing area, characteristic of fast jets.
- Low wing loading: Describes an aircraft design where the weight is low relative to the wing area, characteristic of gliders and slow-flying aircraft.
Noun
- the ratio of the weight of an airplane to its wing area
