Description
technical field:
the utility model relates to a kind of At High Angle of Attack system counter weight device.
background technique:
traditional At High Angle of Attack system ballasting method installs pole and balancing weight in the symmetrical both sides of E type frame, because E type frame stride sizes is large, E type frame due to the torque produced from Rewind System rotating shaft be 16000Nm, need to buy large capacity motor to conduct oneself with dignity the torque produced around the shaft to provide driving moment to overcome E type frame, add cost; When model angle of sideslip reaches 40 °, balancing weight is serious to Flow Field in Wind Tunnel qualitative effects, affects test accuracy.
summary of the invention:
the purpose of this utility model is to provide a kind of At High Angle of Attack system counter weight device.
above-mentioned object is realized by following technological scheme:
a kind of At High Angle of Attack system counter weight device, its composition comprises: device support arm, described device support arm is contained on At High Angle of Attack system framework, below described device support arm, static pulley is housed, described static pulley coordinates with wire rope, described wire rope one end is connected with counterweight pull bar, a set of weights lead described counterweight pull bar is equipped with, described counterweight lead is locked by latch, the described wire rope the other end is connected with bolt draw bar, described bolt draw bar is connected with rotatable parts by nut, one group of angle steel is housed in the middle part of described At High Angle of Attack system framework, described angle steel is connected with round plate, described round plate is built with one group of steel pipe.
described At High Angle of Attack system counter weight device, described counterweight pull bar and described counterweight lead are placed in the passage that described round plate and described steel pipe surround; Described counterweight pull bar is configured with adjusting nut; Described counterweight lead is provided with U-type groove and locking through hole.
beneficial effect:
1. device support arm of the present utility model is arranged on outside At High Angle of Attack system framework both upper ends thereof, is connected with static pulley, and wire line shoe is in static pulley, and one end is connected with counterweight pull bar, and the other end is connected with rotatable parts by bolt draw bar; One group of angle steel is housed in the middle part of At High Angle of Attack system framework, angle steel is connected with round plate, round plate is built with one group of steel pipe, such design makes counterweight pull bar and counterweight lead can move along fixing passage, prevents counterweight lead from the process of moving up and down, causing equipment to collide and injury to personnel owing to rocking; Bolt draw bar is arranged in the straight section through hole of rotatable parts, and end is fixed by nut, and the bolt draw bar the other end is connected with wire rope; Counterweight pull bar one end has adjusting nut, and can realize increase and decrease counterweight lead and the object of fixed weight lead, the counterweight pull bar the other end is connected with wire rope; Counterweight lead has U-type groove and locking through hole, be convenient to quick mounting, counterweight lead utilizes U-type groove to lean against on counterweight pull bar and positions, latch is locked through the locking through hole on counterweight lead, counterweight lead quantity can carry out scene adjustment according to the trim effect of reality, counterweight pull bar moves with rotatable parts, counterweight lead by wire rope by moment loading on At High Angle of Attack system rotatable parts, and then reduce the driving moment of At High Angle of Attack system hydraulic swing motor.
the utility model reduces motor load, improves the stability of a system, by re-starting counterweight conceptual design to At High Angle of Attack system, achieving the effect of " high load with small power ", greatly reducing the expense purchasing motor; Because At High Angle of Attack system balance weight mechanism is installed on rear side of two columns of At High Angle of Attack system framework, when At High Angle of Attack system changes angle of sideslip under upper and lower driven by rotary disc, At High Angle of Attack system balance weight mechanism can be ignored substantially on the impact of Flow Field in Wind Tunnel quality, overcome traditional ballasting method, in E type frame symmetrical both sides, pole and balancing weight are installed, when model angle of sideslip reaches 40 °, balancing weight is serious to Flow Field in Wind Tunnel qualitative effects, affects the problem of test accuracy.
