History Performance
For the purpose of practically testing the position Wingspan ............................................ 9.40m
of the pilot, the Flugtechnische Fachgruppe (Aero- Length max. .............................................. 6.06m
technical Group) Stuttgart constructed the FS17 Height max. .............................................. 2.32m
research aircraft. The FS17 was a glider that was Wheel track ............................................... 2.84m
designed to withstand forces up to 14g. After the Tyre size .......................................... 550x150mm
completion of the test program an order was given Tyre pressures ....................................... Medium
by the DVL ((Deutsche Versuchanstalt fur Luftfahrt Wheel brakes ........................................ Hydraulic
e.V. Berlin-Aldershof) (German Experimental Fuel capacity ................................................. 95L
Department for Aerospace Reg.) to the FFG Berlin Oil tank capacity .............................................. 8L
((Flugtechnische Fachgruppe)(Aero-technical Net weight ................................................ 940kg
Group)) to construct a powered aircraft. FFG Berlin Payload .................................................... 175kg
was chosen as it possessed the necessary Take-off weight ....................................... 1115kg
workshops and technicians. In the Spring of 1943 Duration ......................................... 1 hr. 50 mins.
the FFG Berlin constructed the Berlin B9 to the Flight radius ............................................. 400km
specifications provided. Fuel consumption .............................. 22L/100km
Max. Speed .......................................... 250km/h
The Berlin B 9 was able to achieve accelerations of Cruising speed ...................................... 225km/h
8.5g when pulling out of dives and 6g over several Landing speed ...................................... 105km/h
seconds in steep spiral climbs. Accelerations of Operational ceiling .................................... 4000m
these magnitudes are not endurable by pilots when Time to 1000m ............................... 4 min. 12 sec.
in the normal seated position. At the beginning of Wing loading ......................................... 94kg/m2
the test program, these forces were only Power to weight ratio ............................. 5.3kg/PS
recognised by the heaviness of the head and Surface area loading .......................... 17.7PS/m2
limbs. These forces did not impair the pilot’s Propeller performance ....................... 33.4PS/m2
mental and physical reactions. Because of this,
pilots often underestimated the number of gs they
had pulled.
