Thus, the first three equations of motion can beobtained from (6).The second step of the modeling is to examine the rotational kinematics of the vehicle. Let theangular velocities vector of the vehicle is ν = [p, q, r]T . Using Euler’s rotation theorem [9] andthe rotation matrices given in (2), ν can be expressed as it follows, ˙ ϕ
experiment, and Q is the power input from the DC source to theheating element. [3]Derivation of the Thermal Resistance FormulaThis formula is derived from the basic principles of steady-state heat transfer. In steady-stateconditions, the rate of heat generated by the heating element (𝑄) is equal to the rate at which heatis dissipated through the heat sink into the surrounding environment, with no net energyaccumulation in the system. [4] Thermal resistance in this context functions similarly toelectrical resistance in circuits, where a temperature difference (𝛥𝑇) drives the heat flow just as avoltage difference drives current.The general formula for thermal resistance is defined as: 𝛥𝑇

The area of the sample is measured.InsulationIn the original setup, closed-foam insulation was used. This proved to be a big disadvantagesince it covered the whole setup. It was crucial for the two meter bars to be perfectly aligned asthere needs to be one-dimensional heat flow throughout the whole apparatus. With closed-foaminsulation, there was no way to ensure this condition. It was possible that once pressure wasapplied, there might have been a slight misalignment, and even a minor misalignment couldbring air gaps into the system, making the data inaccurate.
