FIELD: machine building.
SUBSTANCE: invention refers to aircraft industry, and namely to linear telescopic actuator for movement of the first and the second elements relative to fixed element. Actuator includes housing (101) that is attached to fixed element (102) and used as a sleeve for the first stock (106), the rotational movement of which is locked and which can be brought into translational movement with drive shaft (104) that is connected to drive (107) of rotational movement. The first stock is meant to be connected with one of its ends (108) to the first moved element and carries the second stock (117), with which it is aligned along common axis, and to end (118) of which the second moved element is attached. Besides, there is the possibility of locking rotational movement of the second stock (117); besides, it is brought into rotational movement with the second drive shaft (112, 115) that passes through the housing and is connected to drives (113, 111) of rotational movement.
EFFECT: reduction of friction between elements of drive, as well as reduction of its dimensions.
