Shell (projectile) - Wikipedia
Shells are usually large-caliber projectiles fired by artillery, armoured fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons.
M107 projectile - Wikipedia
It used to be the standard 155 mm high explosive projectile for howitzers of the US Army and US Marine Corps, but is being superseded in the US military by the M795. The M107 is a development of the M102 155 mm shell that was developed in the 1930s from the French Schneider 155 mm projectile for the Model 1917 Howitzer.
The Army's New Artillery Shells Can Change Course In Mid-Flight …
2020年7月25日 · Existing guided artillery rounds, often using GPS, Inertial Measurement Systems and advanced seeker technology, have been effective in combat for years, giving ground attack commanders expanded...
M982 Excalibur - Wikipedia
The M982 Excalibur (previously XM982) is a 155 mm extended-range guided artillery shell developed in a collaborative effort between the U.S. Army Research Laboratory (ARL) and the United States Army Armament Research, Development and Engineering Center (ARDEC). [6]
BALLISTICS & DATA - British Artillery
This page gives an outline of ballistics as applied to artillery. It explains the influences on a shell in flight and the variations that they cause, the factors affecting muzzle velocity and the data in and evolution of range tables that enabled corrections for these variations.
A comparative analysis of contemporary 155 mm artillery projectiles
In 2018 the company Nammo developed what is being referred to as “extreme range” artillery. This 155 mm shell incorporates ramjet propulsion technology to achieve long-range precision fires. Without changing any of the features of the current howitzer design, the ramjet projectile can reach more than 100 km (Judson, 2018). This range is ...
Attitude estimation for artillery shells using magnetometers and ...
2022年5月1日 · The article proposes a method to estimate the attitude of an artillery shell in free flight. It uses strapdown accelerometers and magnetometers, and circumvents the intrinsic inability of accelerometers to provide direction information during free flight by employing them not to measure the gravity but to estimate the velocity w.r.t. the air.
The U.S. Army Is Trying to Put GPS Technology in Artillery
2021年11月18日 · Army artillery, armed with GPS and inertial measurement unit-guided Excalibur rounds, are not only fast-developing an ability to change each shell’s course in flight to destroy otherwise...
New Artillery Rounds to Help Army Reach Longer Distances
2022年7月11日 · Base-bleed artillery shells expel gas in flight behind the shell to reduce drag and give them longer range. The 58-caliber Extended Range Cannon Artillery will be utilizing the XM1210 rocket-assisted, high-explosive projectile — formerly designated XM1113ER — to hit targets out to nearly 45 miles.
History and Technology - Shell Aerodynamics 101 - NavWeaps
These brief papers will attempt to address various aspects of shell flight, and document my spare time analysis of heavy artillery shell flight. At its simplest, the drag force acting on a shell, or any other object flying through the atmosphere (or water, or glue, or any other fluid for that matter) is: S = surface area of the base of the object.
