在直升机上安装机枪和航炮有许多不同的方法:舱门枢轴安装;“轴向”安装在机舱下或机身侧面;安装在翼根下的吊舱内或侧面挂架下;装在机头转塔内或机身下.舱门安装主要适合战术运输直升机.在直升机空运期间,所装武器能使敌步兵和非武装车辆在突击部队着陆之前就失去战斗力.例如在法国陆军航空部队装备的SA330美洲豹直升机的右舱门安装着GIATM621 20毫米航炮和意大利Aerea公司研制的12.7毫米机枪用的舱门射击炮塔(DG- P). There are many different ways of installing a machine gun and an artillery gun on a helicopter: the door is pivotally mounted; the “axial” is installed under the nacelle or on the side of the fuselage; the pylon is installed under the wing or under the pylon; Nose turret or under the fuselage. The main installation is suitable for tactical transport helicopters helicopters during helicopters, the installed weapons enable enemy infantry and unarmed vehicles before landing in the assault force on the loss of combat effectiveness, for example, in the French Army Aviation Corps equipment The right hatch of the SA330 Cougar helicopter is fitted with a GIATM621 20mm gun and a 12.7mm gun firing gun turret (DG-P) from Aerea, Italy.
