ice and rain
問題一覧
1
systems are designed to prevent the formation of ice on critical aircraft surfaces by maintaining a surface temperature above freezing or by applying a substance that lowers the freezing point of water.
Anti-Icing
2
systems are designed to remove ice that has already formed on aircraft surfaces during flight.
De-Icing
3
Electric heating elements are embedded in or attached to surfaces like windshields, pitot tubes, and engine inlets. These elements generate heat to prevent ice from forming.
electrical heating
4
Hot air is bled from the aircraft's engines and routed to surfaces such as the leading edges of wings, stabilizers, and engine inlets. The hot air raises the surface temperature above freezing.
hot air bleed system
5
Electric heating elements are embedded in or attached to surfaces like windshields, pitot tubes, and engine inlets. These elements generate heat to prevent ice from forming.
glycol based fluids
6
These are inflatable rubber boots installed on the leading edges of wings and tail surfaces. When activated, the boots inflate, breaking up and shedding the accumulated ice.
pneumatic deicing boots
7
Similar to anti-icing systems, electrical heating can be used in a de-icing role by actively melting ice that has formed on the surfaces.
electrical systems
8
In some cases, glycol-based fluids can also be used as a de-icing measure by applying them to ice-covered surfaces to melt the ice.
fluid application
9
continues use can consume more energy
anti icing
10
typically lower, as system are used intermittently
de icing
11
can cover various surfaces, including wings, windshield, and propeller
anti icing
12
usually limited to specific surfaces like leading edges
de icing
13
highly reliable if maintained properly
anti icing
14
effective but may leave some residual ice
de icing
15
can be costly and complex, requiring maintenance
anti icing
16
generally simplier and more cost effective
de icing
17
2°C to -10°C
Appears Lumpy and Translucent or clear and smooth.
Results from supercooled liquid water droplets striking the surface but not freezing immediately upon contact
tends to form horns or other complex shapes which can significantly disrupt the airflow.
clear ice
18
Between -10°C to -15°C
Appears rough, milky, and opaque.
Formed by the instantaneous freezing of supercooled droplets as the strike the aircraft.
Tends to form conformal or wedge-shaped accretions.
rime ice
19
Between -15°C to -20°C
Combination of clear ice and rime ice
Forms rapidly when ice particles become embedded in clear ice.
Builds a very rough accumulation.
mixed ice
20
is a significant hazard, affecting multiple aspects of the aircraft's performance and safety.
ice accumulation
21
Increased Drag Ice buildup alters the smooth surface of the aircraft, increasing aerodynamic drag.
Decreased Lift Ice on the wings disrupts the airflow, reducing lift.
aerodynamic performance
22
Unbalanced or Frozen Control Surfaces Ice can cause control surfaces to become unbalanced or even freeze in place, making the aircraft difficult or impossible to control.
Jammed Slots Ice can fill and jam both fixed and movable slots, disrupting the designed flow of air over the wings and control surfaces, further degrading the aircraft's handling.
control surface impairment
23
Hindered Instrument Readings Ice can cover sensors like pitot tubes and static ports, leading to incorrect instrument readings.
Impaired Radio Reception Icing can also interfere with radio antennas, affecting communication between the aircraft and ground control or other aircraft.
instrumentation and communication
24
Foreign Object Damage (FOD) Ice, snow, or slush that accumulates on the aircraft can break off and be ingested into engines, particularly those mounted on the fuselage aft or wings.
Structural Damage The weight and impact of ice breaking off can also cause physical damage to the aircraft's structure, particularly to vulnerable parts like propeller blades, leading edges, and engine inlets.
structural and engine damage
25
Gross Weight Increase Ice adds significant weight to the aircraft, which reduces its performance by lowering climb rates, increasing fuel consumption, and extending takeoff and landing distances.
