PC24 Design Features Flashcards
PC24 dimensions
17m wing span
- 8m length
- 3m height
- 8m tail width
Aircraft weights Max Ramp? Max Takeoff? Max Landing? Max ZFW?
Max Ramp - 18400lbs=8345kg
Max Takeoff - 18300lbs=8300kg
Max Landing - 16900lbs=7665kg
Max ZFW - 14220lbs=6450kg
What is Vmo and Mmo?
290kts
0.74 Mach
What is the PC24 constructed from?
Primarily aluminium alloy with composite material structures in certain areas
What methods have been used to reduce parasite drag?
Flush mounted rivets
Recessed door and cargo door handles
Streamlined fairings
Where have area ruling principles been applied on the PC24?
The bottom of the fuselage is raised and the wing box is lowered so they ‘slot into each other
Belly - increased to house main wheels and other services
Engine pylon mounts - scalloped to compensate for pylons and engine nacelles
How many spars does the PC24 incorporate?
3
Front, Rear and Auxiliary spars
How are the wings joined together and to the aircraft?
The wings tension bolted together at the centre rib and the fuselage is joined to the aircraft at the front and rear spars.
What devices are fitted to each wing?
Inner double slotted fowler flaps Outer single slotted fowler flaps Single aileron 2 outboard multi function spoilers 2 inboard lift dumping spoilers Bleed heated leading edge
Describe the aerodynamic features of the PC24 wing?
High lift Variable low sweep (11.6 degrees at 1/4 chord) High wing loading (268.52kg/m squared) Super critical airfoil Medium aspect ratio (8.36)
What is the length of the Mean Chord (MAC)?
1.997m
What is the wing span?
17m
What is the criteria that Pilatus used to calculate/test Mmo?
When stabilised at this speed in level flight, throughout the whole envelope (altitude, weight, CG) you can go through a upset of all 3 axes and:
- Not exceed Vd/Md (max dive speed)
- Not experience any excessive vibration, flutter or control reversal during the upsets
When does the PC24 start to compensate for Mach tuck?
M0.775 with a 0.3 degree pitch up (automatic overspeed deployment of multi-function spoilers at M0.751)
What is shot peening and what surfaces have been treated this way?
Shot peening is a cold work process used to finish metal parts to prevent fatigue and stress corrosion failures and prolong product life for the part. In shot peening, small spherical shot bombards the surface of the part to be finished.
