Dynamic soaring is enabling RC gliders to achieve unprecedented speeds, with some approaching the viability of swept wing designs. This technique utilizes wind shear at hilltops to maximize energy efficiency and speed, similar to how brown pelicans conserve energy while flying. Previous discussions have highlighted the impressive capabilities of dynamic soaring, showcasing videos that demonstrate these extreme speeds. The phenomenon has garnered attention in the RC community, sparking interest in its applications. Overall, dynamic soaring represents a significant advancement in the performance of RC gliders.

I'd heard about this concept for years, and I remember seeing some videos a long time ago of some frankly ridiculous speeds coming from it, but wow. They're pushing RC gliders to speeds where swept wings are starting to become viable. All from wind shear at a hilltop.

Thread 'General principle of turbomachinery: true also for rocket turbopumps?'
A rule of thumb of aircraft engineers is every 10% increase in the power level engines are run at corresponds to a 50% decrease in engine lifetime. This is a general phenomenon of turbomachinery. Then it is likely it also holds for rocket turbopumps. Then quite key is the rule also holds in reverse, every decrease in power level by 10% can result in doubling the lifetime of the engine. Then by running the engine at 0.9^5 = 0.60 power level can result in 2^5 = 32 times longer lifetime. For...
