soft landing
soft landingn.1. The landing of a space vehicle on a celestial body or on Earth in such a way as to prevent damage or destruction of the vehicle.2. Economics A gradual transition from rapid growth to more sustainable levels of economic activity.soft landing n 1. (Astronautics) a landing by a spacecraft on the moon or a planet at a sufficiently low velocity for the equipment or occupants to remain unharmed 2. (Economics) a decrease in demand that does not result in a country's economy falling into recession soft′ land′ing
n. a landing by a spacecraft on a planetary body that is performed slowly, without a jarring impact. [1960–65] soft landingA period of economic slowdown that is successfully managed by a government so that it does not lead to a recession.TranslationsSoft Landing
soft landing[′sȯft ′land·iŋ] (aerospace engineering) The act of landing on the surface of a planet or moon without damage to any portion of the vehicle or payload, except possibly the landing gear. Soft Landing of a space vehicle, a landing in which the velocity of the vehicle at the moment of contact with the surface of a planet or other celestial body is minimal (or in the ideal case, zero). A soft landing is designed to ensure that the structure and systems of a vehicle will remain intact and that the vehicle will be able to continue functioning. The soft landing of winged vehicles (which have wing and body lift), for example, on planets with a sufficiently dense atmosphere necessitates gliding at low speeds and the ability to complete an airplane-type landing. In order to make a soft landing with space vehicles of axisymmetric shape (which have less lift), the vehicles must have deployable landing systems, such as a gliding parachute, paraglider, or rotor system (a type of helicopter rotors). In vehicles with a gliding parachute, additional devices, such as retrorockets, are installed to damp impact upon landing. The soft landing of a spaceship on celestial bodies that lack an atmosphere is accomplished by complete damping of the descent velocity by means of a retrorocket or special shock absorbers. G. A.

Soft landingA term describing a growth rate high enough to keep the economy out of recession, but also slow enough to prevent high inflation and interest rates.Soft LandingA situation in which a central bank raises interest rates gradually, but steadily, to curb inflation, while still attempting to keep the economy out of a recession. A hard landing is generally effective at reducing inflation, but it slows down growth. However, soft landings are considered more desirable than allowing inflation to run amok, which could necessitate a hard landing.soft landing A slowing of economic growth that avoids a recession and the accompanying high unemployment. The Federal Reserve may pursue a restrictive monetary policy to achieve a soft landing when the economy has been expanding at an unsustainable rate. |
