History – Road Map of Events: 1953-1968

1953 Foundation of the Institute of Flight Systems of the German Aeronautical Establishment (DFL) in Braunschweig.

1958-1964 Vertol H 21 dynamic response flight tests and rotor blade deformation measurements using a rotorhead-mounted high speed camera-system. The research objectives included a better understanding of rotor aeromechanics and related flying qualities deficiencies.

1960-1965 Do 27 dynamic response flight tests and flight control augmentation research. Beginning of modeling and parameter identification research.

Do 27 research aircraft
1963-1978 USAF-BMVg/DLR Data Exchange Agreement (DEA): Subsonic Parachute Design, Performance, and Similarity Laws. Also research on dynamic pressure loading and effective porosity of canopies. In total, an exchange of data of 3000 USAF- and 400 DLR-drop tests took place.

FB-Family of parachute drop test vehicles
1963-1983 Large scale flight tests of parachute recovery systems. Development of instrumented drop test vehicles (FB-Family) and personnel dummies. A multitude of flight test programs based on Government contracts was accomplished. In the early eighties, rescue and recovery systems research, development, and evaluation activities of the Institute were discontinued in order to provide manpower for the projected airborne simulator ATTAS.

Rocket-boosted test vehicle FB 6 for DEA research
1965-1968 Various helicopter project support activities for the Ministry of Defense and the Federal Certification Agency (LBA) such as flight testing and certification of steel and fiberplastic rotor blades (GFK-blades System Bölkow) using a special instrumented Alouette II test helicopter provided by the German Army. Consulting activities included the evaluation of the Borgward/Focke Kolibri I helicopter prototype.

Borgward/Focke Kolibri I helicopter prototype
1965-1976 Stability investigations and model validation wind tunnel experiments of parachute-payload systems (cooperation with University of Minnesota, USA).

Ground testing of ejection system recovery systems
1968-1974 Model- and full-scale parachute recovery systems research. Incident and accident research of rescue systems. Analyses, component modifications, ground and flight testing of G 91, F 104, and F 4 rescue systems.

FB drop test vehicle attached to Fiat G 91 of German Forces Flight Test Center
1968-1978 Development and operation of the Free-Flight Parachute Test Facility for parachute experiments in horizontal flight at up to 300 m/s initial velocity.
