Radius of Fillet Formula Elements

Variables
Radius of Fillet
Radius of Fillet measured, a fillet is a rounding of an interior or exterior corner of a part design.
Symbol: r
Measurement: LengthUnit: m
Note: Value can be positive or negative.
Radius of Taxiway Centerline
Radius of Taxiway Centerline taken as guideline, Taxiway centerlines are marked to provide a visual identification of the designated taxiing path.
Symbol: R
Measurement: LengthUnit: m
Note: Value can be positive or negative.
Deviation of Main Undercarriage
Deviation of Main Undercarriage observed. The undercarriage of an airplane is the part, including the wheels, which supports the airplane when it is on the ground and when it is landing or taking off.
Symbol: γ
Measurement: NAUnit: Unitless
Note: Value can be positive or negative.
Minimum Safety Margin
Minimum Safety Margin, The margin of safety allows extra load range in the event the material is weaker than expected or an allowable load that may be higher than anticipated.
Symbol: M
Measurement: NAUnit: Unitless
Note: Value can be positive or negative.
Track of Main Undercarriage
Track of Main Undercarriage considered. Undercarriage is a wheeled structure beneath an aircraft, typically retracted when not in use, which supports the aircraft on the ground.
Symbol: T
Measurement: NAUnit: Unitless
Note: Value can be positive or negative.

FAQs on Radius of Fillet

What is the formula to find Radius of Fillet?
The formula of Radius of Fillet is expressed as Radius of Fillet = Radius of Taxiway Centerline-(Deviation of Main Undercarriage+Minimum Safety Margin+(Track of Main Undercarriage/2)). Here is an example- 36.5 = 150-(95+15+(7/2)).
How to calculate Radius of Fillet?
With Radius of Taxiway Centerline (R), Deviation of Main Undercarriage (γ), Minimum Safety Margin (M) & Track of Main Undercarriage (T) we can find Radius of Fillet using the formula - Radius of Fillet = Radius of Taxiway Centerline-(Deviation of Main Undercarriage+Minimum Safety Margin+(Track of Main Undercarriage/2)).
Can the Radius of Fillet be negative?
Yes, the Radius of Fillet, measured in Length can be negative.
Which unit is used to measure Radius of Fillet?
Radius of Fillet is usually measured using the Meter[m] for Length. Millimeter[m], Kilometer[m], Decimeter[m] are the few other units in which Radius of Fillet can be measured.
