A testing purpose of H3 hypersonic wind tunnel of von Karman Institute for Fluid Dynamics is to do measurements of low temperature ablation phenomenon. The unique long duration testing capabilities of the facility allows stable hypersonic conditions for characterizing aerothermochemistry of thermal protection system (TPS) materials for cruise vehicles and re-entry capsules. Here is one of the first productive tests we have performed after commissioning the new Mach 5 nozzle with Andrea Perin and David Henneaux using wax, gallium and polylactic acid models for validation of numerical simulations. #aerodynamics #hypersonic #schlieren #reentry #aerospace #thermalprotectivesystem #ablation

Fan Fact: The curves towards the tip of turbofan blades are crucial for the efficiency of the engine. In short, they prevent the flow from going critical (supersonic) over the blade, and that prevents the creation of shockwaves. Shockwaves would generate noise, reduce lifetime of the blade, increase maintenance cost, and reduce efficiency. #aerospace

Re-entry temperatures can reach 1,650°C (3,000°F), so the Dream Chaser spaceplane's TPS (thermal protection system) is mission-critical. See how Sierra Nevada used a Dewesoft KRYPTON strain gauge and temperature modules to ensure perfect tile bonding. https://lnkd.in/gcXHUcqp #WeAreDewesoft #testing #measurement #aerospace

The elegant curves of a turbofan blade are not just marvels of engineering aesthetics; they result from the application of simple aerodynamic principles. Some of these principles we learned in school, most in high school, and those of us who took a minor in physics covered the fluid dynamics stuff in university. 1. Bernoulli’s Principle The faster air travels over the blade, the less pressure it exerts. The blade shape uses this principle to work efficiently. This principle is represented by the equation where constant energy equals pressure energy plus kinetic energy (P + 1/2 * rho * v^2 = constant), with P as pressure, rho as air density, and v as air velocity. 2. Lift from Blade Shape Blades are shaped to direct air in a way that creates lift. Lift is directly related to air density, velocity, and the circulation around the blade, as captured by the equation L = rho * v * Gamma, where L stands for lift, rho for air density, v for velocity, and Gamma for circulation. 3. Steady Air Flow The blade design keeps air moving evenly, preventing backups. This is governed by the equation A1 * v1 = A2 * v2, ensuring the product of cross-sectional area (A) and velocity (v) remains constant along the flow path. 4. Air Movement Control The way air navigates around the blade is controlled to reduce turbulence. The Navier-Stokes equations govern this, meaning that the change in air momentum is due to pressure forces, viscous forces, and other body forces. 5. Speed of Sound The blade's ability to handle speeds approaching or exceeding the speed of sound without causing shock waves is crucial as Sayan Bhattacharjee highlights in his post. Here, the Mach number comes into play, comparing the airflow speed to the speed of sound (M = v / a), with M representing the Mach number, v the airflow speed, and a the speed of sound. For hypersonic speeds, the air's behavior changes, necessitating materials and designs that are extremely robust. The blade design must take into account intense heating and stress.

In short, they prevent the flow from going critical (supersonic) over the blade, and that prevents the creation of shockwaves.
