How would we calculate the load factor on an aerial vehicle while landing due to sudden gust loads? In order to design the landing gear (wheels and suspension) of our model Airship, [say "m" kg -expected mass], I wanted to know, is there any way to calculate the loads which might be experienced by the wheels on impact with the ground (taking into consideration the unexpected gust loads - with gust velocity downwards say "V-gust")• 

For simplicity I am Modelling it as a rigid body for now.

Note:- I thought of one way to calculate it, using momentum transfer.

Rate of change of Momentum = Force = density(rho) x projected Area(A) x (V-gust)^2.

Hence,( Gust force + Weight -Buoyant Force) ÷ Mass (m) will give me resultant acceleration.

Q1. Is this a right approach to calculate load?
Q2. Even if it's right, is this the load the wheels will experience during impact?

Please help me clear my confusion.

Edit:- Basically I want my designed landing gear with a normal sink speed upto 3m/s to be able to endure the landing impact even in case of an additional vertical downward gust upto 10m/s at the moment of touching the ground.  This is as specific and clear I could get.
You need at least the stroke of the tire-gear combination to calculate a load. If the airship contacts the ground with a velocity of $w$ and a mass of $m$, the impulse $m\cdot w$ needs to be absorbed by a force $F$ acting along the stroke $s$, as in $m\cdot w = F\cdot s$. Adding airship flexibility will greatly improve the accuracy of the result, because I suspect the hull will deform easily and add to the stroke.
