English

Subject field(s)
  • Landscape Architecture
CONT

Areas of turf, or lawn, provide the green expanse that links all other garden plantings together. They usually consist of grasses--thousands to the square metre--kept shorn close to the ground to provide a green carpet.

OBS

Tapis vert, meaning literally a "green carpet", was first coined in the garden at Versailles in 1680 where André Le Nôtre used a mown grass strip punctuated by urns and statues to divide the main axis, the Allée Royale. This became a template for other grand schemes, including George Washington's plan for the landscaping of independent America's new capital. The term tapis vert has come to embrace a wider meaning, encompassing any area of lawn cut in a regular shape. It is also used to describe areas mown at various heights to produce patterns and it is here that the lawn could enjoy a degree of reinvention, assisted by advances in technology-most mowers can be adjusted by the flick of a lever to give various cutting heights. In areas of a modest size, rotary mowers would be ideal for this purpose.

Domaine(s)
  • Architecture paysagère
DEF

Surface de gazon rectangulaire de grande dimension et sans découpure.

CONT

La période classique introduisit dans les parcs, le tapis vert, pelouse très plate, sobre et peu décorée, généralement en forme de rectangle très allongé, transversalement horizontale mais acceptant très bien une pente longitudinale. On en garnissait le centre des perspectives monumentales. Le tapis vert de Versailles est un modèle du genre.

CONT

Le gazon [...] Les soins d'entretien : tonte, roulage et arrosage doivent être répétés le plus souvent possible, afin d'obtenir un tapis souple et résistant.

Record 2 2011-04-18

English

Subject field(s)
  • Aeronautical Engineering and Maintenance
CONT

The rudder actuator is a tandem actuator, having two internal piston areas for each hydraulic source(A & B). The actuator is capable of positioning the rudder panel with either one or both main hydraulic sources available, though with one source inoperative a reduced rudder panel deflection would result due to blowdown at higher airspeeds. Flow of hydraulic fluid to the rudder actuator is controlled by the dual servo-valve. This is a complex dual concentric cylinder with an outer and inner slide. During normal rudder pedal inputs sufficient rudder panel deflection is catered for by the primary(inner) valve alone. However, should a larger panel deflection be required or a higher rate rudder input be commanded, the secondary(outer) sleeve moves in addition to port extra fluid to the actuator. Movement of the outer sleeve is typically no more than 1 mm. Position of both sleeves of the servo valve is controlled by a complex mechanism of bell cranks, input rod and summing lever, the geometry of which is such as to provide movement of the sleeves in relation to the body of the valve.

English

Subject field(s)
  • Flight Controls (Aeroindustry)
  • Landing Gear (Aeroindustry)
CONT

The MLG [main landing gear] retracts inwards into the fuselage wheel well. Each MLG has two doors. The outboard door is rigidly attached at the strut. The inboard door operates by mechanical linkage to the strut and is held in up position by two uplock cylinders. This uplock is released when landing gear lever is placed in down position by hydraulic pressure, or by nitrogen pressure in emergency. The MLG is held, while airborne, in retracted position by hydraulic pressure in the actuator and by the inboard door mechanical uplock, if pressure drops. As the gear is extended, an internal lock in the actuator automatically locks it in fully extended positions.

DEF

A braking system which is independent of the main hydraulic system. It can be used to slow or stop the vehicle if the primary brakes fail, or to hold the vehicle stationary though the brake pedal is not depressed. It usually consists of a foot pedal or hand lever that actuates either front or rear brakes mechanically through a series of cables and linkages.

Subject field(s)
  • Flight Controls (Aeroindustry)
CONT

Even when the designer has settled the size and angle of the tail plane, the force which it will experience will be outside the control of the pilot, and although they may automatically compensate for such things as changes in pitching moment on the main planes, they cannot possibly deal with changes of weight such as are caused by the dropping of bombs, consumption of fuel, and changes in the disposition of passengers and cargo. For this reason the adjustable tail plane was introduced, this being operated by an actuating gear and controlled by a wheel or lever in the pilot's cockpit. This enabled the pilot to alter the angle of setting of the tail plane during flight and so cause downward or upward forces upon it at will, thus balancing the aeroplane under all conditions.

Aileron control is supplemented by the flight spoilers which are controlled by the spoiler mixer. The spoiler mixer senses aileron movement and automatically provides the correct amount of spoiler deflection.

There are two lateral control mixers, one located in each main gear wheel well. The mixers allow the spoiler system to be operated by the speedbrake control lever, by the aileron control wheels, or by both simultaneously.... Each mixer consists of a bracket; a shaft supporting the aileron input drum, aileron output drum, and a spoiler cam; two cam follower arms; two spoiler sectors; and connecting links, cranks, and pushrods.
