Determination of Fighter Cockpit DEP Based on WEPs of Pilots in Simulated Flight
The working eye position (WEP) of 256 Chinese male pilots were tested in simulated flight to determine the design eye position (DEP) of advanced fighter cockpit. Four WEPs were defined in that (1) WEP-C, i.e. the WEP with seated posture of cruise, (2) WEP-L, i.e. the WEP with oblique posture of left sway, (3) WEP-R, i.e. the WEP with oblique posture of right sway, and (4) WEP-G, i.e. the WEP with bowed posture of anti-G load in a simulated recurrences of their mission flight for level linear cruise or rapid maneuvers. The results were found that the WEP-L showed significantly about 30 mm left-shifting with 3 mm downward-shifting marginally, the WEP-R showed significantly about 40 mm right and 18 mm backward shifting with 3 mm downward-shifting, and the WEP-G showed significantly about 10 mm downward-shifting in contrast with the WEP-C. The DEP should be pointed at (0,125,755) in (x, y, z) above neutral seat reference point (NSRP) based on WEPs of pilots rather than point (0,155,795) in GJB35B, and the HUD design eye box (DEB) may be in size of 340 mm wide, 195 mm high, and 470 mm deep better than 340, 185, and 415 mm without the WEP-G.
