Variable pitch
| Словарь терминов и сокращений в авиации |
- Изменяемый шаг; изменяемого шага (о воздушном винте)
- Said of an aerial or marine propeller in which the angle of the blades can be adjusted to optimize thrust. the mathematics of propulsion efficiency are extremely complex, but can be simplified by comparing propeller pitch to an automobile transmission. low gear and fine pitch each provide good acceleration but limited speed. high gear and coarse pitch provide greater thrust, allowing higher speed but less acceleration. ships with engines that work most efficiently at a steady pace can vary their speed by changing the pitch of their propellers. in contrast, a fixed pitch propeller can be more efficient at its designed speed and load, but is less flexible than one which can be adjusted to absorb virtually all the power the engine can produce at any combination of speed and vessel loading. (variable pitch is also called adjustable pitch or controllable pitch.)

(see ship motion, rotational oscillation.)

Mathematics, английский
- The science which treats of every kind of quantity that can be numbered or measured.
- Математика
- Originally, the science of number and quantity. but with the birth pf numerous more qualitative formalisms, (e.g., logic, propositional calculi, set theory), with the emergence of the unifying idea of a mathematical structure, with the advent of the axiomatic method emphasising inference, proof and the descriptions of complex systems in terms of simple axioms, and, finally, with self-reflective efforts such as meta-mathematics, mathematics has become the autonomous (->autonomy) science of formal constructions. emphasising its formal character and its applicability to all conceivable worlds, mathematics has been likened to a language whose semantics is supplied by other sciences or by particular applications. although all constructions are inventions of the human mind, cannot be found in nature and have no necessary connection with the world outside mathematics, they nevertheless arise in conjunction with solving certain kinds of problems:(1) real world problems, (e.g., geometry evolved in efforts of measuring the earth, game theory grew out of concerns for social conflict resolution, statistics from the need to test hypotheses on large numbers of observations, recursive function theory from the desire for efficient algorithms,) (2) intellectual curiosity and playfulness, (e.g., markov chain theory stems from interest in poetry, probability theory from games of chance, the four-color problem, symmetry and much of topology (see the mobiusband) from`interest in artistic expression), and (3) interest in the powers and limitations of ma thema tics and the mind, (e. g., goedel` s incompleteness theorem from the inherent undecidability or incompleteness of systems, the theory of logical types from disturbing paradoxes, the differential and integral calculi from efforts to transcend the smallest distinctions practically possible). ,however, it is a characteristic of mathematics that the problems giving rise to its constructions are soon forgotten and the constructions develop a life of their own, checked only by such validity criteria as internal consistency, decidability and completeness. empirical data from an existing world do not threaten the products of mathematics. 48 matrix; a many-dimensional arrangement of numbers suitable to various transformations which form the basis of matrix algebra. a one-dimensional matrix is called a scalar. most frequent are two-dimensional, n-by-m, matrices which might contain the coefficients (->parameter) of a set of linear equations or specify a mapping from an n-dimensional to a m-dimensional vector space (->hyperspace).
