A model airplane for testing inside a wind tunnel has a fuselage and is mounted on a sting. A balance or force transducer is mounted on a forward end of the sting inside the fuselage of the model airplane and is of the strain gauge type for measuring forces acting on the model airplane. A plenum chamber for receiving air is mounted forwardly of the balance inside of the fuselage of the model airplane. At least one air feed line extends from the sting to the plenum chamber and bypasses or bridges over the balance. An external air source feeds air from the...
A model airplane having a fuselage for testing inside a wind tunnel, comprising: a sting; an air source, connected to the sting, for feeding air through the sting; a balance for measuring forces acting on the model airplane, said balance being mounted on the sting; a plenum chamber for receiving air therein, said plenum chamber being mounted inside the fuselage in communication with the balance; and at least one air feed line extending from the sting to the plenum chamber and bypassing the balance; whereby negligible force interactions from air flowing i...
