The ICAO SMS Module 5 indicated there are three basic "defenses to aviation risk". List and explain how these defenses may be applied in aviation safety.
If the specific enthalpy of nitrogen is given by the formula H (kJ/kg) = 1.04 [T (°C) - 25] what is the volumetric flow rate of the gas (L/s) upstream of the heater (i.e., at 30°C and 110 kPa)?
A hypersonic gun tunnel is used to generate short-duration, high-speed flows and typically consists of two cylindrical volumes separated by a diaphragm. One end of the tunnel (the driver end) is pumped to a high pressure, while the other end (the dri..
