The invention discloses a high-load and high-precision pneumatic force
measurement device and a measurement method. An internal balance
tail-supported aerial vehicle model is adopted to execute pneumatic force test in the prior art, and rising force of an aerial vehicle perpendicularly works on a
cantilever type
tail rod, so that the model severely shakes during the test. The high-load and high-precision pneumatic force
measurement device comprises a balance and a supporting rod, wherein the balance adopts an internal balance and is connected with a balance sleeve; the supporting rod is connected with an incidence angle sliding rail mechanism, a side sliding angle mechanism connected with the incidence angle sliding rail mechanism, and a mechanism control and
data acquisition device; the supporting rod is adopted to be connected with the balance and support the model; the internal balance is adopted to measure the pneumatic force of the aerial vehicle model; the balance is externally connected with a sleeve structure and is also connected with a
data acquisition device; the
data acquisition system obtains the pneumatic force on the model and is connected with
automatic control equipment; therefore, the pneumatic force on the model can be obtained. The high-load and high-precision pneumatic force
measurement device and the measurement method are used for measurement in a pressurized high-density and low-speed wind tunnel.
