Condition:
| Actuating wheel doors. A 6 wings with four MG 151.
2 MG 131 instead of 2 MG 17 in the fuselage. (without runs bullet channels covered.)
|
1. | Ram pressure calibration over the test course.
| 2. | Determination of level speeds with combat power.
|
1, 2) | Level speeds up to 22,966 feet (7000 meters) were determined using combat power, taking into account air speed indicator error, and can be found plotted on the attached graph.
Compared to the A5 series (2 MG 151 + 2 MG 17) values, the speeds of 816 are around ~ 9 mph (15 km/h) lower across the board. From this loss is about 3 mph (5 km/h) from the two additional MG 151 runs and ~ 6 mph (10 km/h) due to the changes for the installation of the MG 131 cover front windscreen (see Flight Report Fw 190/861 with 2 MG 17 + 4 MG 151).
|
Remark:
| In level flight the cover inflates in front of the wind shield in the area of the MG 131 bullet channels, so that an additional bolt is required.
It remains to be tested to what extent the measured speeds were influenced by this.
