The sled was then accelerated according to the experiment's design requirements for data collection along a length of isolated, precisely level and straight test track. Testing ejection seat systems and technology prior to their use in experimental or operational aircraft was a common application of the rocket sled at Holloman Air Force Base .
A rocket sled launch, also known as ground-based launch assist, catapult launch assist, and sky-ramp launch, is a proposed method for launching space vehicles. With this concept the launch vehicle is supported by an eastward pointing rail or maglev track that goes up the side of a mountain while an externally applied force is used to accelerate ...
The packing and lashing of a sled is an art. Weight must be carried low on the sled, to reduce the risk of tipping. Ingenious structures and materials are used to protect the passengers and hunters build small sleek versions to permit fast day trips. The qamutiik were traditionally hauled by trained dog teams.
Illustration of a simple three-axis gimbal set; the center ring can be vertically fixed. A gimbal is a pivoted support that permits rotation of an object about an axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first ...

High-altitude military parachuting, or military free fall (MFF), is a method of delivering military personnel, military equipment, and other military supplies from a transport aircraft at a high altitude via free-fall parachute insertion.
In a majority of these serious cases, young children are riding runner sleds in a prone position, and suffer hand and finger injuries when they are caught under the runners or between the sled and another object. [3] In addition, runner sleds force the weight of the rider onto two thin runners where the pressure causes a microscopic film of ...
A hardpoint is an attachment location on a structural frame designed to transfer force and carry an external or internal load.The term is usually used to refer to the mounting points (more formally known as a weapon station or station) on the airframe of military aircraft that carry weapons (e.g. gun pods and rocket pods), ordnances (bombs and missiles) and support equipments (e.g. flares and ...
