Modeling the Transient Dynamics of Arresting Hooks and Cables

Arresting gear systems play a vital role in carrier-based aircraft landing. In order to accurately understand the process of arresting hook and cable, this study introduces a parameter inversion method to model the arresting cable and applies it to the transient dynamics model of the arresting hook and cable. The feasibility of the arresting cable model and its application to the

How much of the service life of an arresting cable is reduced?

Between 50 and 70% of the service life of the cable is reduced due to the dynamic loading effects. A novel technique based on the solution of a continuous elastic system is proposed for analysing the displacements and stresses on an arresting cable due to the impact of a landing aircraft.

arresting-cable installations. An aircraft operating on runway 10R would use the cable at the far end for both landing and aborted takeoff unless the aircraft had an emergency, at which point the arresting gear nearest the approach end of the run-way would be used. The installation criteria for cable systems on commercial runways are

electromagnetism

Resistors - kinetic energy is converted to thermal energy, inductors - kinetic energy is stored in a magnetic field, capacitors - potential energy is stored in an electric field from charges. Now connect a voltage source (i.e. battery) across an inductor with zero stored energy or a length of copper wire with parasitic inductance.

In the latter the kinetic energy of the fighter is transferred to the heat and then dissipated. Figure 1. Arresting gear cable drawing arresting gear cable into two parts - take-up cable and braking - it is possible to interchange periodically the take-up cable, because its external plies undergo abrasion and rupture due to dynamic

Why is an aircraft carrier''s arresting cable made from steel?

$begingroup$ Kevlar alone will not stop a knife attack, it needs a "stab resistant" material as well, like a chain-mail overlay or very thick panels. And as @ymb1 said, once Kevlar stretches, it doesn''t rebound like steel, you could say it is much more brittle. Most Kevlar vests are junk after a single bullet, and if you hit the same spot twice, it would not stop the bullet.

carrier during landing, the arresting cable shows ten-sion fluctuations in the process of hindering. If the energy absorption during landing is not enough, the arresting cable easily leads to enormous tension fluctu-ations, even more than the maximum tension indicator of the arresting cable. In the new control technology, the semi-active con-

Nonlinear dynamic analysis of arresting gears using 2D non

The arresting cable system has an important feature in that the length of the arresting cable on the aircraft carrier deck varies greatly during the arresting process. [44,45], some additional terms representing inflow and outflow of the kinetic energy must be considered. However, for the derivation of the equation of motion of a variable

Vibration and fatigue life of an arresting cable under impact

The response of the arresting cable owing to the impact of the landing aircraft is modelled as a problem of initial conditions. The maximum normal and tangential stresses are determined for different landing conditions and landing aircraft sizes. The fatigue life of the wire is determined based on classical theories.,The results show that

a land-based emergency standby gear for arresting hook-equipped aircraft (Figure 9-1). It is installed on the runway for the purpose of safely arresting an aircraft in the event of an aborted takeoff or an emergency landing. The arresting engine is a rotary, hydrodynamic energy absorber installed outside the edges of the runway.

The cable is connected to arresting gear below decks that absorbs the aircraft''s kinetic energy and stops the aircraft. Service life of the cable under repeated mechanical loading and degradation-inducing environmental conditions is critical, since the cable is the largest driver of operational cost in the Aircraft Launch and Recovery

Reliability analysis of arresting hook engaging arresting cable for

Before the main landing gear wheels touch the deck, if the arresting hook does not hook a certain arresting cable, the next cable that the arresting hook encounters will be a cable that has been rolled by the aircraft wheels, and the impact of the vibration of the cable after wheel rolling on the reliability of engaging the cable cannot be ignored. 3 Therefore, to
