TW381164B - Shrouded aerial bomb - Google Patents

Abstract

A target-penetrating aerial bomb includes a penetrating body shaped for improved target penetration, having a narrower impact profile at approximately the same weight as an existing bomb. An aerodynamic shroud encases the penetrating body and emulates the aerodynamic shape of the existing bomb, and the weight, center of gravity and moments of inertia of the bomb (the penetrating body and shroud) closely approximate those properties of the existing bomb. The bomb according to the invention may be qualified for flight by similarity to the existing bomb, and thus, avoid lengthy and costly qualification procedures.

Description

V. Description of the Invention 领域 Field of the Invention The present invention is a bomb. The 4 L has a background of invention. The bomb basically has a hard shell. The aerodynamics and bomb 1M from the aircraft bow "bomb, gliding through the test, its" accuracy. Medium. Therefore, the newly-invented considerable time of the invention outlines the airdrop. The bomb is used for bombing from the aircraft. " Yu Bei penetrating an air-dropped bomb with a hard target. T contains the physical characteristics of an internal: bomb used to contain explosive substances, including weight, center of gravity, and rotation :; the two forms' will affect the free fall of the bomb. It has nothing to do with the bombs, including free-fall guided or non-guided bombs, and booster bombs, which must be projected to the target & second test through the strict release of the safety release on the aircraft. The development of the weapons necessary to introduce the weapon carrying the bomb before it was certified for use was delayed and costly.

The ability to merge 2 or other projectors through the target is directly proportional to the impact and speed of the projector, and inversely proportional to the cross section of the bomb. That is, the smaller the kinetic energy is, the smaller the expected penetration force is. In order to make the existing explosive j · ', have a greater penetration force, reducing the outer diameter of the bomb can be achieved, but = and t will change the mass properties such as weight, center of gravity, moment of inertia, and gas characteristics, these Will affect the flight characteristics of the bomb. These changes must also be matched by the use of the bomb check. The invention provides an air-drop bomb, which can overcome the difficulties in passing the quality, and can match the aerodynamic characteristics and quality characteristics of the qualified bomb.
