Definitions
- the invention relates to an adjusting device for rudders a missile, with the rudders of servomotors over Thrust spindles adjustable and the servomotors in one arranged in the rear of the missile carrier housing are.
- Such a control device is in the DE 43 35 785 A1.
- Another adjusting device for rudder one steerable projectile is in DE 34 41 533 C2 described. There is a favorable Coupling device between the rudder and a Linear actuator specified. This can be by means of presetting an adjusting device.
- a bearing assembly for the pivotable rudder blade a steerable missile, in particular a means Propellant charge gas pressure bullet, is known from DE 34 41 534 A1.
- the object of the invention is an adjusting device of initially mentioned type with a particularly compact design propose.
- the stators of the servomotors in the carrier housing are self-installed, spare themselves own Motor housing, which saves space and a Weight reduction means. Even in a cramped Missile tail can be two servomotors with parallel Axles are installed side by side. So it is not necessary, the servomotors staggered in the longitudinal direction in the Rear to arrange, which would increase the overall length.
- a servomotor serves to adjust a pair of rudders.
- the other servomotor serves to adjust the other Rowing pair.
- a small length is also possible because of the Engage spindles in the internal thread of the motor shafts.
- the compact design is with a weight reduction connected.
- the extremely small and lightweight Actuator is particularly suitable for a a projectile capable of firing a mortar (mortar round), has the rudder.
- a short length of the actuator is characterized supports that the internal thread into which the Thrust spindle engages within a motor shaft bearing rolling bearing is located.
- the carrier housing is so designed that it arranged in the rear area, the Rear area of the projectile against radial forces, especially Gayak instruction supported. This is enough one reduced wall thickness of the rear area, creating a Weight savings and an installation space with enlarged Inner diameter is possible.
- the inner ring and the outer ring supports one the motor shaft bearing rolling bearing at a Launch acceleration of the missile in the carrier housing from.
- this is in the carrier housing a Disc provided.
- a projectile which can be fired by means of a propellant charge (Mortar round) carries in the rear area 1 a pair of oars Rowing 2 and a rowing couple with oars 3.
- the oars 2.3 can be folded out about axes A (see Fig.4 with Fig.1) and by means of an adjusting device about rudder axes B pivotable.
- the adjusting device has a carrier housing 4, which is inserted in the rear area 1.
- the dimensionally stable carrier housing 4 supports the rear area. 1 radially to the projectile longitudinal axis F and decreases while the Launching resulting radial compressive forces, so that the Wall thickness of the rear area 1, where it is from Carrier housing 4 is supported, smaller than usual can. This increases the usable space in the interior of the Rear area 1.
- a Servomotor 5 for adjusting the one rudder pair and a Actuator 6 for adjusting the other pair of rudders intended.
- the motors 5,6 are next to each other (see. Fig.3,4). Their motor shafts run parallel to each other. Both motors 5,6 are the same structure and in the same Way connected to the associated rudder pair. in the The following is for simplicity only the one engine and its coupling to its rudder pair described. For the other engine applies accordingly.
- the engine is brushless and without housings. His stator 7 is inserted directly into the carrier housing 4, glued, for example. His rotor 8 sits on the Motor shaft 9.
- the motor shaft 9 is at both ends by means in the Carrier housing 4 used rolling bearings 10, For example, angular contact ball bearings stored.
- rolling bearings 10 For example, angular contact ball bearings stored.
- a disc 11th intended.
- the outer ring 12 of the Rolling bearing 10 At this is the outer ring 12 of the Rolling bearing 10 on.
- the Disc 11 In the region of the inner ring 13, the Disc 11 a step 40 with respect to the rolling bearing 10 well-defined game between inner ring 13 and Outer ring 12 on.
- the inner ring 13 of the solves deformed elastically by the firing acceleration Bearing again from the disc 11, so that the inner ring 13th free is.
- the Motor shaft 9 an internal thread 14, in which an axial movable, secured against rotation thrust spindle 15 engages with an external thread 16.
- an engagement nut 18 At the other end of the thrust spindle 15 sits on an external thread 17 an engagement nut 18, with one attached to the axis B of a pair of oars Mit Cyprus lever 19 is coupled.
- the Engagement nut 18 By twisting the Engagement nut 18 can be the position of the rudder axis Adjust B relative to the push spindle 15.
- the Adjustment position is by means of a lock screw 20th fixable.
- the specified actuator is small and comparatively easy. Few moving parts are enough for a smooth-running gear train.
- an arm 21 is attached to the an actuator 22 of a linear potentiometer 23rd attacks.
- the linear potentiometer 23 is connected to one in the room 24 arranged control electronics connected.
- the Linear potentiometer 23 is in a recess 25 (see. 3) of the carrier housing 4 is arranged.
- about the Linear potentiometer 23 is the control electronics, the actual position reported the respective rowing couple.
- Linear potentiometers can also be used for other measures Detecting the actual position of the rudder be provided.
