Environmental Sensing Device (military)/Related Articles
Environmental Sensing Device (military): Weapon safety devices that prevent detonation until they detect external conditions consistent with the known mode of delivery, such as changing barometric pressure and radar altitude of a dropped bomb, or the launch acceleration, conditions in space, and reentry of a ballistic missile trajectory; a key safeguard for nuclear weapons
This article contains just a definition and optionally other subpages (such as a list of related articles), but no metadata. if you want to expand this into a full article.
- Safety features in U.S. nuclear weapons : Those design techniques and specific components, inside or immediately adjacent to U.S. nuclear weapons that minimize the chance of unauthorized nuclear detonation or contamination due to accident or deliberate action; they complement Positive Control, stockpile testing, and other U.S. nuclear surety techniques not adjacent to the weapons
- Ballistic missile : A guided missile which, once its engines stop firing, follows a generally parabolic path to its target, defined by momentum, aerodynamic resistance, and gravity
- Gravity bomb : A bomb with no supplemental propulsion, whose trajectory is determined by initial velocity and gravity, or by the action of aerodynamic control surfaces.
- Accelerometer : Most commonly, a sensor used to measure acceleration in one reference axis; also an aircraft instrument that reports the instantaneous acceleration in the flight path
- Barometer : Add brief definition or description
- Radar altimeter : Altimeter which calculates altitudes, by sending a radio signal straight down from an aircraft and to measure its total time of travel to the surface and back to the aircraft.
