摘要
为了获得××飞机主要部件和外挂物的气动载荷,在气动中心高速所1.2m×1.2m风洞中进行了飞机部件和外挂物同时测力试验研究。在M=0.40～0.85,α=-4°～12°,β=-8°～8°的试验条件下,采用7台天平同时对该飞机主要部件(机翼、平尾和垂尾)及翼下外挂物进行了测量。结果表明:试验获得的飞机部件和外挂物气动特性变化规律合理,量值可靠。试验研究的成功,拓宽了风洞试验能力,提高了风洞试验效率。
An investigation on aircraft component and externalstores forcemeasurement was conducted in 1.2m×1.2m high speed wind tunnel to determine a certain aircraft component and externalstores aerodynamic characteristics. Seven straingage balances were used to obtain force and moment data on aircraft component and externalstores under the conditions of M=0.40～0.85,α=4°～12° and β=8°～8°. Test results show that the test is successful, test data are reasonable and reliable. Successful application of this technique increases the test capability and efficiency of wind tunnel test.
