what the advantages and disadvantages of these different kind of wings ?
( delta wing , swept wing , swing wing ,Trapezoidal wing )
why aircraft like mig-25 , f-15 use swept wing in stead of delta design ( they are much faster than mirage , F-106 )
why the nose of space shuttle is not so sharp ( isn’t it reduce more drag if it sharp :confused:)
what decide the top speed of aircraft ?
why the bell x-1 with weak thrust and very trapezium wing can even reach mach 2.44 while aircraft like f-35 , f-16 have much slower speed
a new air speed record of Mach 2.44 (equal to 1620 mph, 724.5 m/s, 2608 km/h at that altitude). Unlike Crossfield in the Skyrocket, Yeager achieved that in level fligh

how did the bell x-2 even reach mach 3.12 with it very low thrust engine and not very low drag profile compared to sr-71
