|
| | Reason: | In the course of further development on the Me 109 G, flight tests with MK 108 mockups were to be carried out in accordance with instructions from Prof. Messerschmitt.
| |
| Test
Procedure: | One test flight each, with and without mockups, was conducted. The values are not converted, since the two short flights took place consecutively and a change of the air state did not take place during the short time dismantling the mockups.
|
| Results: | Speed without mockup | Vw = 326 mph (525 km/h)
| |
| | | Speed with mockup | Vw = 322 mpg (519 km/h)
| |
| | | Speed loss due to mockups | ΔV = 4 mph (6 km/h)
| |
| | | n = 2600 U/min; p – 1,30 ata; B = 717 mm Hg;
| | | t = 19°C; H = 480 m.

| Aircraft: | Me 109 G Wk.Nr. 15562 Kennz.: CN + WF
| |
| | Engine: | DB 605 A/1 W.Nr. 37648
| |
| | Propeller: | 3-blade. VDM Adjustable D = 3,0 m
Blattbaumuster 9 – 12159 A
Satz-Nr. 3 buf 75

| Condition of
the Machine: | Standard production version ME 109 G with GM 1-equipment. Surface specially treated, yet somewhat smoother than Test Report 109 11 L42 shows achieved. Radiators closed; radiator indicator staffs; wing thermometer; Chassis; tail wheel out. Mockups for MK 108 from wood. Implementation and mounting see photo. 2 ETC 50 one behind the other beneath under the fuselage.
| |
| Process of
Measurements: | Two test flights at combat power n = 2600 RPM, p = 1.30 ata at ground level. Air pressure was measured by altitude recorder on board the machine, temperature at ground.
| |
| | | 1. Flight: with MK 108 mockup.
| | | 2. Flight: without MK 108 mockup.
