FIELD: rocketry; guide rockets of various types and classes provided with lattice control surfaces. SUBSTANCE: rocket is made according to normal aerodynamic configuration and is provided with engine plant, guidance and monitoring equipment, fixed wings and movable lattice control surfaces evenly located on body relative to its longitudinal axis and control surface opening mechanism for locking the control surfaces in open and folded positions. Rocket is provided with pyrotechnic high-pressure gas container and lattice control surfaces are provided with pins having bores for locking the control surfaces in folded position; rocket body is provided with holes to receive these pins, mounting holes being provided in root portions of control surfaces. Each control surface opening mechanism is made in form of pneumatic cylinder and shaft arranged in rocket body and secured in front portion of tail-piece of control surface drive shaft with its ends received by respective mounting holes in root portion of control surface. Under-piston chamber of pneumatic cylinder is brought in communication with pyrotechnic high-pressure gas container; its piston is spring-loaded for locking in extreme position in opening the control surface. Each mechanism for locking the control surface in open position is made in form of spring-loaded rods fitted in rear portion of shaft tail-piece of control surface drive for engagement with respective mounting holes provided in root portion of control surface; each mechanism for locking the control surface in folded position is made in form of grabbing shears mounted in rocket body for engagement with pins of control surfaces in folded position and with rods of pistons of pneumatic cylinders in open position of control surfaces; rods of pneumatic cylinder pistons have length sufficient for closing the holes in rocket body when control surfaces are in open position. EFFECT: enhanced reliability of locking control surfaces in folded and open positions making the rocket body- and splash-proof and excluding damage to coats of body and planes of lattice control surface. |
