Advertised missile performance:
Natural Frequency 0.65
a = Angle of attack [rad]
q = pitch rate [rad]
= 1.25m center of gravity
Xcg
Zcg = Om center of gravity
The equations of motion for the missile are
a = q - 0.435sin a + 0.07a -0.00014q
q = 111.484(xcg - 1.483)a - (2.2968 - 3.156zcg)q +3.448 + 137895Zcg
To acquire the target the missile needs to fly at
α = 0.017 [rad] qo= 0 [rad/s] = 0 [rad]
So
Determine if the missile is stable about the given equilibrium point.

Define a python function to determine the 2nd moment of area I, under the parabola, with respect to the centroidal-axis. The
parabolic curve is defined as z = ky2, where k = b/h². The centroidal axis has a given distance d with respect to z axis.
Hints: Use the parallel axis theorem. Find the 2nd moment of area against z axis first and then use the formula I₂ = I₁ + d²A to
calculate I, where d is a given value (no need to derive). Note that this question requires you to derive the equation first.

Required information
A cylindriçal fuel rod (k 30 W/m K) of 2 cm in diameter is encased in a concentric tube and cooled by water. The fuel rod
generates heat uniformly at a rate of 100 MW/m, and the average temperature of the cooling water is 80°C with a
convection heat transfer coefficient of 2500 W/m4-K. The operating pressure of the cooling water is such that the surface
temperature pf the fuel rod must be kept below 200°C to avoid the cooling water from reaching the critical heat flux (CHF).
The crițical heat flux is a thermal limit at which a boiling crisis can occur that cause overheating on the fuel rod surface and
lead to damage.
