DLR is for instance investigating wing flutter and possible ways of eliminating it, which would also help to reduce aircraft noise.
The tanks damped wing flutter and also kept wingtips close to the ground for ease of maintenance.
The German Aircraft Research Institute used it to perform statistical analyses of wing flutter.
The designer was flight testing the prototype Model A when it suffered wing aeroelastic flutter.
Both test series demonstrated a variety of problems, including failures of the rocket casings, and excessive drag and wing flutter.
It was later test flown from Farnborough but was lost after wing flutter developed; both pilots escaped safely by parachute.
The prototype was rejected because of lack of manoeuvrability as well as suffering from a serious wing flutter and ineffective rudder control.
It was here that he contributed to aircraft safety with his studies on the problem of wing flutter and the stability of structures.
He compared the system to testing an airplane for structural strength, seeing a wing flutter unexpectedly and then flying even faster.
Baptiste was killed in March 1933 during an aerobatic demonstration of the 201 T, first flown that January, a crash caused by wing flutter.
