Sergey Chaplygin
Sergey Alexeyevich Chaplygin (russian: Серге́й Алексе́евич Чаплы́гин; 5 April 1869 – 8 October 1942) was a Russian and Soviet physicist, mathematician, and mechanical engineer. He is known for mathematical formulas such as Chaplygin's equation and for a hypothetical substance in cosmology called Chaplygin gas, named after him. He graduated in 1890 from Moscow University, and later became a professor. He taught mechanical engineering at Moscow Higher Courses for Women in 1901, and of applied mathematics at Moscow School of Technology, 1903. He was appointed Director of the courses in 1905. Leonid I. Sedov was one of his students. Chaplygin's theories were greatly inspired by N. Ye. Zhukovsky, who founded the Central Institute of Aerodynamics. His early research consisted of hydromechanics. His "Collected Works" in four volumes were published in 1948. Honours and awards * Hero of Socialist Labour (1 February 1941) * Two Orders o ...

Chaplygin, Lipetsk Oblast
Chaplygin (russian: Чаплы́гин) is a town and the administrative center of Chaplyginsky District in Lipetsk Oblast, Russia, located at the confluence of the Stanovaya Ryasa and Yagodnaya Ryasa Rivers, north of Lipetsk, the administrative center of the oblast. Population: History The settlement of Ust Stanovykh Ryas () was founded on the territory of modern Chaplygin in the first half of the 17th century. It later grew into the village ('' selo'') of Slobodskoye (). In 1695, Peter the Great built a small wooden palace in the vicinity, and in 1702 a small fortress under the name of Oranienburg (). The name, originally taken from that of the German town Oranienburg, was modified to Raninburg and later to Ranenburg (). Also in 1702, both the fortress and the village of Slobodskoye were granted to Alexander Menshikov, who built a small monastery here in 1712. Town status was granted to Ranenburg in 1778. In 1948, it was renamed Chaplygin after the Russian physicist Sergey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chaplygin (crater)
Chaplygin is a large lunar impact crater that lies on the far side of the Moon. It is located to the southeast of the huge walled plain Mendeleev, about midway between the craters Schliemann to the northeast and Marconi to the southwest. It is about the same size as Albategnius on the near side. The rim of this crater is roughly circular; however, the edge is uneven. The inner wall is terraced around much of the circumference, and this structure is somewhat disrupted along the southern side. The rim is only mildly eroded, with few craters around the edge — the exception being Chaplygin K which is intruding into the inner wall along the southeast side. Within the walls is an interior plain that is level and smooth in comparison to the rugged terrain that surrounds the exterior of the crater. There is a central peak near the midpoint, and a few tiny craters lie scattered across the surface. A small, bright crater on the northeastern rim is called Chaplygin B. It is nick ...

4001–5000
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other ha ...

Chaplygin Gas
Chaplygin gas, which occurs in certain theories of cosmology, is a hypothetical substance that satisfies an exotic equation of state in the form p = -A/\rho^\alpha , where p is the pressure, \rho is the density, with \alpha = 1 and A a positive constant. The substance is named after Sergey Chaplygin. In some models, generalized Chaplygin gas is considered, where \alpha is a parameter, which can take on values 0 < \alpha \le 1. See also *Dark fluid
In astronomy and cosmology, dark fluid theories attempt to explain dark matter and dark energy in a single framework. The theory proposes that dark matter and dark energy are not separate physical phenomena, nor do they have separate origins, but ...

Chaplygin Problem
In mathematics, particularly in the fields of nonlinear dynamics and the calculus of variations, the Chaplygin problem is an isoperimetric problem with a differential constraint. Specifically, the problem is to determine what flight path an airplane in a constant wind field should take in order to encircle the maximum possible area in a given amount of time. The airplane is assumed to be constrained to move in a plane, moving at a constant airspeed In aviation, airspeed is the speed of an aircraft relative to the air. Among the common conventions for qualifying airspeed are: * Indicated airspeed ("IAS"), what is read on an airspeed gauge connected to a Pitot-static system; * Calib ... ''v'', for time ''T'', and the wind is assumed to move in a constant direction with speed ''w''. The solution of the problem is that the airplane should travel in an ellipse whose major axis is perpendicular to ''w'', with eccentricity ''w''/''v''. References * * * Calculus of ...

Chaplygin Sleigh
The Chaplygin sleigh is a simple pedagogical example of a nonholonomic system in mechanics, described by Sergey Chaplygin Sergey Alexeyevich Chaplygin (russian: Серге́й Алексе́евич Чаплы́гин; 5 April 1869 – 8 October 1942) was a Russian and Soviet physicist, mathematician, and mechanical engineer. He is known for mathe .... It consists of a body that slides frictionlessly on a horizontal plane, with a knife edge that constrains its motion so that the knife slides only longitudinally. Because this constraint is nonholonomic, Liouville's theorem does not apply, and although energy is conserved, the motion is dissipative in the sense that phase-space volume is not conserved. The motion is attracted to an equilibrium, in which the sleigh moves without rotation, with the knife edge trailing the center of mass. There are several ways of seeing that the system is nonholonomic. The dimension of the phase space is 5, which is odd. The co ...

Chaplygin's Equation
In gas dynamics, Chaplygin's equation, named after Sergei Alekseevich Chaplygin (1902), is a partial differential equation useful in the study of transonic flow. It is : \frac + \frac\frac+v \frac=0. Here, c=c(v) is the speed of sound, determined by the equation of state of the fluid and conservation of energy. For polytropic gases, we have c^2/(\gamma-1) = h_0- v^2/2, where \gamma is the specific heat ratio and h_0 is the stagnation enthalpy, in which case the Chaplygin's equation reduces to : \frac + v^2\frac\frac+v \frac=0. The Bernoulli equation (see the derivation below) states that maximum velocity occurs when specific enthalpy is at the smallest value possible; one can take the specific enthalpy to be zero corresponding to absolute zero temperature as the reference value, in which case 2h_0 is the maximum attainable velocity. The particular integrals of above equation can be expressed in terms of hypergeometric functions. Derivation For two-dimensional potential flow, t ...
