The Integrated Helmet and Display Sight System (IHADSS) 30 mm M230 chain gun turret on a Boeing AH-64 Apache being aimed with a helmet-mounted sight A helmet-mounted display (HMD) is a headworn device that uses displays and optics to project imagery and/or symbology to the eyes.
The previous helmet-like display was replaced by a flat display with better clarity, better line-of-sight, and also a hinge that allows the display to be flipped up. As a result, the field of view was reduced from 70 degrees to 60 degrees. The thermal camera was also being improved to increase clarity while reducing power consumption. [4]
Another early and more noble helmet video camera was a 1977 head-mounted camera designed to convert images into tactile sensations for the blind. [ 3 ] Almost a decade later, a Canon CI-10 camera was mounted to the side of Dick Garcia's helmet by Aerial Video Systems (AVS) of Burbank, CA at the Nissan USGP 500 World Championship at Carlsbad ...
A main assisted reserve deployment (MARD) system is a skydiving safety device for parachute systems. While there are many variations, the operation and intended outcome for each is the same: open the reserve parachute container and extract the reserve parachute's deployment bag (and parachute) using the jettisoned main canopy.
A flight helmet, sometimes referred to as a "skull dome", "bone dome" or "foam dome", is a special type of helmet primarily worn by military aircrew. A flight helmet can provide: [ 1 ] Impact protection to reduce the risk of head injury (e.g. in the event of a parachute landing) and protection from wind blast (e.g. in the event of ejection ).
The three-ring system is simple, inexpensive, reliable, and requires fewer operations than earlier parachute release systems while reducing the physical force needed. The large bottom ring is securely attached to the skydiver's harness, the middle ring is securely attached to the end of the parachute riser, and the small ring is securely ...
4-way FS (Formation Skydiving) Breaking off from a formation before parachute deployment. DC-3 loading; plus 'dirt diving'; 1977. Formation skydiving is a skydiving event where multiple skydivers attach themselves to one another by grabbing each other's limbs or by the use of "grippers" on their jumpsuit while free falling through the sky.
A ripcord is a part of a skydiving harness-container system; a handle attached to a steel cable ending in a closing pin. The pin keeps the container closed and keeps the spring-loaded pilot chute inside. When the ripcord is pulled, the container is opened and the pilot chute is released, opening the parachute.
