HOT AIR ENGINE [11 records]

Record 1 2026-03-19

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

The energy depleted airflow that passed the turbine, in addition to the colder air that bypassed the engine core, produces a force when exiting the nozzle that acts to propel the engine, and therefore the airplane, forward. The combination of the hot air and cold air are expelled and produce an exhaust, which causes a forward thrust.

The intake-manifold heat control system should pass hot air through, or against, the intake manifold only when the engine is cold. When the engine is warm, the hot exhaust gases should not contact the intake manifold. The valve that takes care of this job is often called the heat-riser valve.

Subject field(s)
  • Aircraft Propulsion Systems
DEF

A gas turbine engine in which the net energy available is utilized by the air or hot gas solely in the form of a jet issuing through a propelling nozzle. [Definition standardized by the BSI. ]

OBS

CONT

Un turboréacteur est un turbomoteur dont toute l'énergie utilisable provient exclusivement de la vitesse des gaz d'échappement; on récupère en effet toute leur énergie cinétique pour produire par réaction une poussée permettant le déplacement d'un avion ou bien d'un aéronef quelconque.

OBS

turboréacteur : terme uniformisé par le Comité d'uniformisation de la terminologie aéronautique (CUTA) - Opérations aériennes et par l'Organisation de l'aviation civile internationale (OACI).

Subject field(s)

CONT

The XB-25E was a standard production modified for anti-icing research. The carburetor air intake duct was faired internally into the top of the cowling and an anti-icing air intake was mounted at the bottom. Each row of cylinders exhausted through a separate exchanger, one ported outboard and one inboard of each nacelle. Ram air from the lower cowling duct was routed underneath the engine to a split duct, each side of which was directed to one of the heat exchangers. Air admitted to these heat exchangers was directed through a series of gates that allowed diversion of heated air either to the anti-icing system or out the exhaust. A complex system of ducting led the hot air to the outer wing leading edges and also into the fuselage and to the leading edges of the tail. It was intended that the temperature of the hot air would be sufficiently high that ice on the wing leading edges surfaces would be vaporized rather than melted, which would have prevented water from flowing aft and then freezing again on flaps and ailerons.

Use of this anti-icing liquid/air heat exchanger, in conjunction with the proper air and liquid flow controls, will permit savings of total cooling air(i. e., engine bleed air) flow by negating the need for a hot air bypass to reheat turbine exhaust air.

Subject field(s)
  • Atmospheric Physics
CONT

The world's biggest Low is caused by hot air rising near the equator(it is called the Equatorial Low). Its position moves north and south during the year as it follows the movement of the overhead sun and the latitude of greatest heating. The Equatorial Low is the heat ’engine’ that powers the entire global circulation. Cloud and rain are produced by rising air, making the Equatorial Low also the world's main rain-producing area and the place of the great tropical rainforests.

[...] voyons comment se déclenche un El Niño. En situation normale, l'ensemble de l'eau qui recouvre la planète est plutôt froide. Toutefois, au nord de l'Australie et de la Papouasie-Nouvelle Guinée, il existe une masse d'eau chaude, la plus chaude de la Terre. C'est à partir de cette eau chaude que se forment les nuages qui entraînent les moussons. Cette masse d'eau chaude est gardée en place grâce aux alizés, vents soufflant des hautes pressions subtropicales vers les basses pressions équatoriales. À cause de ces vents, les eaux sont plus élevées d'une trentaine de centimètres dans l'ouest du Pacifique que dans l'est.

The starter air shutoff valve incorporates a pneumatic heater tube which taps into the pneumatic duct system upstream of the butterfly valve. This provides a continuous flow of hot air on the valve body and switcher mechanism to prevent freezing or to thaw a frozen valve, when APU/engine operates. The pneumatic heater tube is removable for cleaning and to facilitate unblocking.
