Example page from a bullet journal, showing some typical notations. A bullet journal (sometimes known as a BuJo) is a method of personal organization developed by digital product designer Ryder Carroll. [1] [2] The bullet journal system organizes scheduling, reminders, to-do lists, brainstorming, and
A flechette or flèchette (/ f l eɪ ˈ ʃ ɛ t / fle-SHET) is a pointed, fin-stabilized steel projectile. The name comes from French flèchette (from flèche ), meaning "little arrow" or " dart ", and sometimes retains the grave accent in English: flèchette .
A needlegun, also known as a needler, flechette gun or fletcher, is a firearm that fires small, sometimes fin-stabilized, metal darts or flechettes. Theoretically, the advantages of a needlegun over conventional projectile firearms are in its compact size, high rate of fire , and extreme muzzle velocity .
The principle of the kinetic energy penetrator is that it uses its kinetic energy, which is a function of its mass and velocity, to force its way through armor. If the armor is defeated, the heat and spalling (particle spray) generated by the penetrator going through the armor, and the pressure wave that develops, ideally destroys the target.
A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired.
A journal, from the Old French journal (meaning "daily"), may refer to: Bullet journal, a method of personal organization; Diary, a record of personal secretive thoughts and as open book to personal therapy or used to feel connected to oneself. A record of what happened over the course of a day or other period
An explosive-dispersed flechette (if intact) would also be tumbling and quickly lose its velocity, useful range, and effectiveness. Constructing a bomblet that with flechettes makes no sense. Flechettes get their momentum/velocity by being accelerated in a gun (artillery, shotgun, or rifle-like).
The flechette rounds were developed under a contract administered by Picatinny Arsenal and let to the Whirlpool Corporation in April 1957. The contract was named the "Beehive Program" referring to the way the flechettes were compartmentalized and stacked, looking like the traditional image of a conical beehive.
