Experienced Engineers and Pilots
With your experience, how doth vibration relate to wing size (span, depth, thick, m2), speed, altitude (and method flying), and MTOW (that day). (Could say if propellor (and)else jet), and any notes of manouevres.
If a 14m wingspan single fuselage airplane flying at different altitudes (Sea Level, 1000ft, 2000ft, 3000ft, E.T. CetERa), from nr stall to 100kts, 200kts, 300kts, 400kts, 500kts, 600kts, 700kts, 800kts, 900kts, what the experience of the pilot, what the experience of the airplane.
If a 14m wingspan wing, 5m chord at wingtip, though 11-12m chord at root, solid wing say 0.3metre thick and say 90-130m2, say 6g (could be 9g) low level, what the experience (stall to 1000kts). Tolerable. Horrid. Beautiful. (K)New Set Teeth. Wish use ffffaacccciiiilLITeaseee. Calvin (and Hobbes) sight on too much caffeine.
We each know the long thin wing for low level flying hence less vibration since less chord (though weight of centre fuselage and wing fuel/engines affecting oscillation), though what the experience of pilots with different wings (and if jet, if propeller (on wing, on nose)).
What the experience of Tornado and F14 low level with spread wings (and what rough max speed)
What the experience of Tornado and F14 low level with swept wings (and what rough max speed)
What Vibration spectra and tolerance
If cruise
(If 14m span, 90-130m2, 5m tip, 11-12m root, say 0.3m thick, 50kts 100kts 200kts 300kts 400kts 500kts 600kts 700kts 800kts 900kts 1000kts
500ft 1000ft 2000ft 3000ft......42,000ft.)
If shortterm manoeuvre (and what stress calc for such wing if +6g (could be 9g)(and -2-6g) if structure wood, else composite, else metal, (think low level military flying and acrobat).
MTOW 10,000kg, 15,000kg, 20,000kg, 25,000kg, 30,000kg, single fuselage (though shall have weight store outboard each wingtip)
Some say the Blackburn Buccaneer relatively smooth low-level flight though say Panavia Tornado relatively rough
Some say the DeHavilland Vampire very smooth and long glide
What tolerable airplane
and what airplane of vibration a problem for the pilot
