A projectile is any object thrown into space (empty or not) by the exertion of a force. Although any object in motion through space (for example a thrown baseball) may be called a projectile, the term more commonly refers to a ranged weapon. Mathematical equations of motion are used to analyze projectile trajectory. An object projected at an angle to the horizontal has both the vertical and horizontal components of velocity. The vertical component of the velocity on the y-axis given as Vy=USin(teta) while the horizontal component of the velocity Vx=UCos(teta). There are various terms used in projectiles at specific angle teta 1. Time to reach maximum height. It is symbolized as (t), which is the time taken for the projectile to reach the maximum height from the plane of projection. Mathematically, it is give as t=USin(teta)/g Where g=acceleration due to gravity(app 10m/s²) U= initial velocity (m/s) teta= angle made by the projectile with the horizontal axis.
Projectile firing device using liquified gas propellant
Rifle (1) comprises barrel (2) and loading means (15) for introducing a projectile from magazine (7) into breech (4). The projectile is propelled by a compressed gas propellant initially stored as a liquid in canister (10). The liquid is heated to a super critical state in chamber (8) by heating element (12) to induce a phase change such that the liquid becomes a highly dense gas. The phase change from liquid to gas provides the energy required to expel the projectile at high velocity from rifle (1), regardless of the ambient temperature. The propellant is preferably CO2 which is heated to 31.06° C. Rifle (1) produces minimal noise and no heat signature, making it suitable for military and stealth purposes. A pistol and launchers for grenades or mortar bombs are also disclosed. Another version can launch low earth orbit satellites or payloads.

Subsonic ammunition casing
A subsonic ammunition cartridge casing having an engineered internal volume designed to allow for the introduction of precisely the amount of propellant necessary at precisely the desired location to reproducibly produce the desired projectile velocity and internal pressure is provided. The subsonic shell casing has an engineered internal propellant cavity built into the internal body of the casing itself that does not necessarily depend on the introduction of a separate volume reducing device such as tubing, filler, foam filler and the like. This ensures the integrity of the case, does not result in anything being expelled through the muzzle of the weapon other than the projectile, does not have any burning or combusting components, allows for very precise control of the internal volume and thus chamber pressure, and is economical to produce.

High volume multiple component projectile assembly
A projectile includes a head, a tail, and an interface that interconnects the head and tail. Multiple sections of the interface are deformed by being compressed radially inwardly into respective annular recesses formed between the interface and the head and tail during manufacturing or by rifling when the projectile is fired. The amount of deformation is controlled by the depth of each of the annular recesses. In all embodiments, annular ridges formed in the head, the tail, or both, define the longitudinal extent of the annular recesses. The interface includes an annular obturation region and has a beveled open leading end to facilitate insertion of the head and tail into the interface.

A muzzle loading firearm projectile is disclosed that is composed of a multi diameter, hollow base solid copper bullet, the rear cavity filled with a material of low-density, and a gas pressure seal that separates the bullet from the powder charge. The majority of the bullet shank has a diameter less than the bore diameter of the firearm barrel to allow for ease of loading and alignment of the barrel and bullet axis; a narrow ring of material larger than the barrel bore diameter but less than the groove diameter is located at the junction of the bullet shank and nose profile that centers the bullet in the barrel and positively positions the bullet over the powder charge regardless of orientation of the firearm. The low-density material filling the rear cavity of the bullet acts as an expansion medium when impacted by the rear gas seal during the firing process causing the hollow shank of the bullet to expand and lock into the barrel rifling.

Ballistic reticle for projectile weapon aiming systems and method of aiming
ActiveUS20050229468A1Good compensationCompensation effectSighting devicesHorizontal axisOptical power
A reticle of a projectile weapon aiming system such as a riflescope includes a primary aiming mark adapted to be sighted-in at a first selected range and further includes a plurality of secondary aiming marks spaced apart below the primary aiming mark. The secondary aiming marks are positioned to compensate for ballistic drop at preselected incremental ranges beyond the first selected range, for a selected group of ammunition having similar ballistic characteristics. Angles subtended by adjacent aiming marks of the reticle can be adjusted by changing the optical power of the riflescope, to thereby compensate for ballistic characteristics of different ammunition. In some embodiments, the reticle includes a set of windage aiming marks spaced apart along at least one secondary horizontal axis intersecting a selected one of the secondary aiming marks, to facilitate compensation for the effect of crosswinds on the trajectory of the projectile.

Apparatus and methods for variable sweep body conformal wing with application to projectiles, missiles, and unmanned air vehicles
InactiveUS6923404B1Improve aerodynamic efficiencyImprove aerodynamic performanceAircraft stabilisationUnmanned aerial vehiclesBody axisUncrewed vehicle
An unmanned air vehicle (“UAV”) apparatus is configured to have a body and a body-conformal wing. The body-conformal wing is configured to variably sweep from a closed position to a fully deployed position. In the closed position, the body-conformal wing span is aligned with the body axis and in the fully deployed position the body-conformal wing span is perpendicular to the axial direction of the body. Delivery of the UAV comprises the steps of: positioning the span of a body conformal wing in alignment with the axis of the body of the UAV; initiating the flight of the UAV; and adjusting the sweep angle of the body-conformal wing as a function of the current speed, altitude, or attack angle of the UAV, with the adjustment starting at a 0 degree position and varying between a closed position and a fully deployed position. The UAV also has a control mechanism configured to variably adjust the sweep of the body-conformal wing to achieve a high lift over drag ratio through out the flight path of the UAV.
