Only in the most general terms, and from first principles: Composite structures will have a higher stiffness per unit mass, which will cause the fundamental frequencies to be higher both for the pure structural modes and the control surface

In practical terms, flutter due to approaching transonic conditions is probably pretty rare. That kind of flutter is (mostly or most often) due to the interaction of normal shocks with the control surfaces, or coupling with an elastic mode

Another version of this course (I think it was an OCW version on YouTube.) had a video of a fish holding position in a stream. There was an obstacle in the stream, and the fish swam up into its wake to save energy. Neat. Then they showed

This very much depends on the model space in question. If our model space includes “climate continues normally” and “climate gets weird/warm over time” models, then an event that occurs that is an outlier for “normal,” but routine for

My problem with this article is the focus on the "startup" mythology of moving fast and breaking things. Break a Coulomb barrier, first, and then come talk to us. I really liked https://www.youtube.com/watch?v=L0Ku

Slightly off topic, but I can't play first person shooters--or, heck, even Minecraft--because I get motion sick from simulated motion with no actual motion. It's so bad that when I used to try to play, I'd continue to be sick

What's interesting to me about this is that no major airline wants to go supersonic, for two reasons. First, because of the cost of development, and, second, because you lose a significant fraction of business class revenue to your sup

The critique of the propulsion scheme was laid out in the video. It was just framed in a way that tried to dodge the reality that this system cannot scale. For example, rather than presenting the thrust densities in a table for easy compari

No energy is being continuously invested by gravity. It is not "keeping the reaction going" in that sense. It's simply freshman physics that tells us that forces only do work when they act through a distance. Because the star
