Слайд 5

Three common types of landing gear

Слайд 6

Purpose of Landing Gear
To provides structural support to the aircraft for

ground operation
To provides maneuverability for ground operation
To provides a mean to absorb unusually loads incurred during landing and ground operation

Design considerations

Слайд 8

Design considerations
Maximum strength
Minimum weight
High reliability
Overall aircraft integration
Low cost
Airfield compatibility

Слайд 9

Design consideration
Landing Gear should locate near the center gravity (CG) of

the plane
CG location are depended on aircraft configuration, loading, fuel state.

Слайд 10

Landing Gear Developments
Noise Reduction
As engines become quieter, landing gear is now

making a dominating component of noise in large commercial aircraft
European co-financed research project Silencer is trying to create low noise landing gear design
Desires 10db reduction in landing gear noise by 2020, has only dropped 3db so far

Слайд 11

Gear up landing prevention system
NTSB reports that the majority of gear

up landings are due to equipment malfunctions.
Gear up landing prevention systems will disengage autopilot and alarm at a preset safety altitude if every piece of landing gear is not extended and locked.
It can be disengaged if a belly landing is the only option.
Materials
Composites will be integrated into gear because they are stronger and cheaper than the current used high strength steels and titanium
