Basic diagram of an onager, a type of catapult. A catapult is a ballistic device used to launch a projectile a great distance without the aid of gunpowder or other propellants – particularly various types of ancient and medieval siege engines. [1] A catapult uses the sudden release of stored potential energy to propel its payload.
The Flyer moved forward under its own engine power and was not assisted by catapult, a device the brothers did use during flight tests in the next two years and at public demonstrations in the U.S. and Europe in 1908–1909. A headwind averaging about 20 mph gave the machine sufficient airspeed to become airborne; its speed over the ground was ...
Developed in the 1950s, steam catapults have proven exceptionally reliable. Carriers equipped with four steam catapults have been able to use at least one of them 99.5% of the time. [1] However, there are a number of drawbacks. One group of Navy engineers wrote: "The foremost deficiency is that the catapult operates without feedback control.
The Modern Use section here says "Ships also use them to launch torpedoes and deploy bombs against submarines". I'm a bit dubious about this; I'm guessing the editor who put it there is thinking of the WWI “bomb-thrower”, or the later “depth-charge thrower”, but AFAIK both those used an explosive to give the propulsive effect.
The catapult used on aircraft carriers consists of a track or slot built into the flight deck, below which is a large piston or shuttle that is attached through the track to the nose gear of the aircraft, or in some cases a wire rope, called a catapult bridle, is attached to the aircraft and the catapult shuttle.
In linguistics, Immediate Constituent Analysis (ICA) is a syntactic theory which focuses on the hierarchical structure of sentences by isolating and identifying the constituents. While the idea of breaking down sentences into smaller components can be traced back to early psychological and linguistic theories, ICA as a formal method was ...
Catapult Health’s trailing twelve-month revenue was approximately $30 million as of the third quarter of 2024. The transaction is expected to close in the first quarter of 2025, subject to customary closing conditions. Following the closing of the transaction, Catapult Health will operate within the Integrated Care segment of Teladoc Health.
In syntactic analysis, a constituent is a word or a group of words that function as a single unit within a hierarchical structure. The constituent structure of sentences is identified using tests for constituents. [1] These tests apply to a portion of a sentence, and the results provide evidence about the constituent structure of the sentence.
