What is commonly used landing gear?
Arguably the most common type of landing gear,tricycle-type gear includes the main gear and the nose gear. It’s typically used on both large and light aircraft. With this design, the two main wheels are attached to the airframe behind the center of gravity. There are quite a few benefits to tricycle-type landing gear.
What is the importance of landing gear safety devices?
L anding gear safety devices have many important functions, among the most critical of which is to prevent the landing gear from retracting or collapsing while the aircraft is on the ground. Gear indicators are another important safety device.
What are the dangers of titanium?
Titanium has the ability to affect lung function causing lung diseases such as pleural disease, it can cause chest pain with tightness, breathing difficulties, coughing, irritation of the skin or eyes. It is carcinogenic and may also cause cancer.
Is the landing gear stationary or retractable?
The landing gear supports the aircraft during landing and while it is on the ground. Simple aircraft that fly at low speeds generally have fixed gear. This means the gear is stationary and does not retract for flight. Faster, more complex aircraft have retractable landing gear.
Which is the correct configuration of the landing gear?
Aircraft Landing Gear Configuration The landing gear supports the aircraft during landing and while it is on the ground. Simple aircraft that fly at low speeds generally have fixed gear. This means the gear is stationary and does not retract for flight.
What makes a good landing gear for an airplane?
Landing gear must be strong enough to withstand the forces of landing when the aircraft is fully loaded. In addition to strength, a major design goal is to have the gear assembly be as light as possible. To accomplish this, landing gear are made from a wide range of materials including steel, aluminum, and magnesium.
How often do landing gears in aircraft fail?
Failure of landing gears in aircrafts represents approximately a 10% of the total of failures reported for the aerospace industry. This chapter discusses the main causes of these failures, their prevention, and a complete analysis of three cases of failure of this kind of components.
What kind of landing gear should I use?
For small aircrafts, a lip spring type of landing gear is normally sufficient to absorb the impact energy. For heavier aircrafts, oleo pneumatic landing gear strut are the normal choice. Landing gears are generally “safe life” components and are replaced many times during the service life of an aircraft.
What kind of load does a landing gear bear?
Aircraft landing gear is a most essential support of an aircraft during landing and ground operations. It is attached with primary structural members of an aircraft. Generally a landing gear has to bear heavy compressive load, drag load and side load. Drag load and side load values are very small when compared to compressive load.
Why is steel used in aircraft landing gear?
For many years, steel has been used in aircraft landing gear because of its high stiffness, strength, fatigue resistance and toughness. However, high-strength steels are susceptible to corrosion and hydrogen embrittlement, which is the phenomenon whereby steel becomes very brittle owing to the absorption of hydrogen.
Why is titanium used in aircraft landing gear?
Forged titanium is used in airframes requiring high strength and high toughness or when there is too little airframe space for aluminium alloys. For many years, steel has been used in aircraft landing gear because of its high stiffness, strength, fatigue resistance and toughness.
