Researchers Test Minuteman III Intercontinental Ballistic Missile

As an unarmed Minuteman III intercontinental ballistic missile (ICBM) rocketed into the night sky, a team of Lawrence Livermore National Laboratory (LLNL) researchers listened intently to radio chatter and watched flight data stream in from a control room at the Ronald Reagan Ballistic Missile Defense Test Site. It was the first of two flight tests conducted recently to verify that the system could deliver a payload to target.

Rising Temps Could Limit Aircraft Takeoffs

Rising temperatures due to global warming will make it harder for many aircraft around the world to take off in coming decades, says a new study by Columbia University. As air warms, it spreads out, and its density declines. In thinner air, wings generate less lift as a plane takes off. Depending on aircraft model, runway length, and other factors, at some point, a packed plane may be unable to take off safely if the temperature gets too high.

Using System Simulation to Manage Increasing Thermal Loads on Aircraft Fuel Systems

Today’s modern military fighter jets are like “a flying thermos bottle” according to Steve Iden, AFRL Invent Program Manager [1]. Many engineers have been saddled with trying to put the thermal loading constraints of these fighter jets on ice. This places increasing demands on utilizing the fuel system as a heat sink to dissipate thermal loads coming from onboard electronics, oil and hydraulic systems, avionics bay cooling, and weapons modules. Engineers today are looking to simulation to help tackle these design challenges, and they have more power than ever with simulating fuel systems to evaluate feasible system designs with given requirements on thermal power loading, fuel capacity, and tank geometry. With a given set of key performance metrics and limits on a design, the design space can be quickly explored to find optimum metrics such as flight mission duration or required component sizing to meet thermal load requirements.
