DE2318305A1 - BRAKING DEVICE FOR A PAYLOAD EJECTABLE FROM A SHOE ON THE AIRWAY - Google Patents

Description

Braking device for one from a bullet shell on the flight path Ejectable payload The invention relates to a braking device for a vehicle a bullet shell on the trajectory ejectable payload, which with a tragfalischirin is connected and ejected opposite to the flight direction of the projectile casing and the brakes are applied until the parachute can withstand the forces of the air can.

With such projectile shells, the payload becomes small Powder charge ejected at a predetermined point on the trajectory. As a braking means a parachute is usually used for the payload, which immediately after the Ejection becomes effective and the payload brakes until the parachute breaks can withstand attacking air forces.

in a successful bombardment, for example with flares, it is important that the period of time between the perception of the fire and the possible defense and protective measures are kept small.

Accordingly, the invention aims to shorten this braking process in terms of time.

According to the invention, the payload is spin or wing stabilized and combine with a solid-fuel engine as braking means for translation and rotation, which is arranged in the ogive of the projectile shell.

This shortens the braking process and therefore also the period between the perception of the fire and the possible defense and protective measures. Compared to der.i, the braking parachute, which is limited in its dimensions, can in particular a shorter braking time can be achieved at high projectile speeds: also the powder charge for discharging the payload can be omitted.

The arrangement of the solid fuel engine in the ogive makes the Space for the payload not impaired.

In the drawing is an embodiment of the braking device shown according to the invention. It shows Figure 1 the bullet shell with built-in Payload, Figure 2 shows the situation after the payload is ejected during the braking process and FIG. 3 shows the luminous element after opening the suspension parachute.

According to Figure 1, the projectile casing 5 has a time fuse 4 and a Base plate 7, which is fixed with 8 shear pins. The payload consists of a flare pot 1 connected to a parachute 2, with which the braking means serving solid propulsion unit 7 is detachably connected, which after ignition through the time 4 both the ejection and the braking process up to to release the parachute 2 causes.

In FIG. 2, the situation after the payload has been ejected with the Flare box 1, the parachute 9 and the solid-fuel engine 3 during the Braking phase shown.

From the empty bullet shell 5, the base plate is before the ejection 7 has been sheared off. In those cases that slow down the rotation of the payload make necessary, this can be done by deflecting the jet of the solid fuel engine.

Figure 3 shows the ignited flare pot 1 on the open parachute 2. After the solid fuel engine 3 has burned out, it has been thrown off. Delay and / or ignition charges for the flare pot can be used at the end of the fire 1 can be ignited by the solid fuel engine 3. This can fuses before the burnout cancel, whereby the parachute 2 is released.
