1. Aerodynamics & Gas Dynamics

Isentropic Flow = T₀/T = 1 + ((γ-1)/2) M²

Normal Shock Relation = M₂² = (2 + (γ-1)M₁²) / (2γM₁² - (γ-1))

Prandtl-Glauert Rule = C_p = C_{p0} / √(1 - M_∞²)

2. Propulsion & Rocketry

Rocket Thrust = F = ṁ v_e + (p_e - p_a) A_e

Tsiolkovsky Equation = ΔV = I_sp g₀ ln(m₀ / m_f)

Thermal Efficiency = η_th = 1 - (1 / r_p^((γ-1)/γ))

3. Flight Mechanics

Breguet Range (Jet) = R = (V / c_t) (C_L / C_D) ln(W₀ / W₁)

Breguet Endurance = E = (1 / c_t) (C_L / C_D) ln(W₀ / W₁)

Neutral Point = x_np = x_ac + η_t (a_t / a) (S_t / S) l_t (1 - dε/dα)

4. Aerospace Structures

Bredt-Batho Torsion = q = T / (2 A_m) | θ = (T L) / (4 A_m² G) ∮ (ds/t)

Shear Flow in Open Beams = q_s = - (V_y / I_xx) ∫ y t ds

Euler Buckling Load = P_cr = (π² E I) / (K L)²

5. Space Dynamics & Orbits

Orbital Velocity = v = √(μ (2/r - 1/a))
