A shock absorber (in reality, a shock "damper") is a mechanical or hydraulic device designed to absorb and dampshock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. A shock absorber is a type of dashpot.
Description
Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below).
One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy can be stored and used later. In general terms, shock absorbers help cushion vehicles on uneven roads.
An infrared countermeasure (IRCM) is a device designed to protect aircraft from infrared homing ("heat seeking") missiles by confusing the missiles' infrared guidance system so that they will miss their target (Electronic countermeasure).
History
First deployed during the Vietnam War, they have been enhanced over the years to be lighter, more portable, and more reliable, but the basic principle is the same.
Infrared missile seeker technology
Infrared missile seekers of the first generation typically used a spinning reticle with a pattern on it that modulates infrared energy before it falls on a detector (A mode of operation called Spin scan). The patterns used differ from seeker to seeker, but the principle is the same. By modulating the signal, the steering logic can tell where the infrared source of energy is relative to the missile direction of flight. In more recent designs the missile optics will rotate and the rotating image is projected on a stationary reticle (a mode called Conical scan) or stationary set of detectors which generates a pulsed signal which is processed by the tracking logic.
Most shoulder-launched (MANPADS) systems use this type of seeker, as do many air defense systems and air-to-air missiles (for example the AIM-9L).
Friction disk shock absorbers or André Hartford dampers were an early form of shock absorber or damper used for car suspension. They were commonly used in the 1930s but were considered obsolete post-war.
Origins
The friction disk pattern was invented by Truffault, before 1900. These used oiled leather friction surfaces between bronze disks compressed by adjustable conical springs, with the disk pack floating between arms to both chassis and axle, in the distinctive style. From 1904 these were licensed to several makers including Mors, who had first applied shock absorbers to cars, and Hartford in the US. Similar dampers were also applied as steering dampers from this early date.
Construction
The dampers rely, as their name suggests, on the friction within a stack of disks, clamped tightly together with a spring and clamp bolt.
André Hartford pattern
The friction disk material was usually a wooden disk between the two faces of the steel arms. As for the development of the clutch and brake shoes, the development of these friction materials was in its infancy. Treated leather had been used for clutches and although it offered good friction behaviour, it was prone to stiction when first moving off and also failed when overheated. Asbestos-based friction materials were sometimes used for racing, in an attempt to keep dampers working correctly even when overheating.
