wes.copernicus.orgGlauert's optimum rotor disk revisited – a calculus of variations solution and exact integrals for thrust and bending moment coefficientsAbstract. The present work is an amendment to Glauert's optimum rotor disk solution for the maximum power coefficient, CPmax, as a function of tip speed ratio, λ. First, an alternate mathematical approach is pursued towards the optimization problem by means of calculus of variations. Secondly, analytical solutions for thrust and bending moment coefficients, CT and CBe, are derived, where an interesting characteristic is revealed pertaining to their asymptotic behavior for λ→∞. In addition, the limit case of the non-rotating actuator disk for λ→0 is shown for all three performance coefficients by repeated use of L'Hôpital's theorem, and its validity is discussed in the context of other works since Glauert.

#DOGE Is Putting Major Government #Efficiency Projects at #Risk

“18F was the people’s #tech shop,” one fired #18F worker tells WIRED. “There’s a giant hole left by the closure of 18F. Requests from across the country for help far outpaced 18F’s capacity before the closure.”

America is Trapped in a Burning Tesla

"Imagine how a private #business would react if it hired a supposed #efficiency expert who quickly fired crucial employees while making grandiose claims about the money he’s saving, but kept releasing progress reports that were full of ludicrous errors...

But #Trump went out of his way to praise #Musk...

Sooner or later... important things are going to break."

Text from article (edited for length): ...Musk let a bunch of Dunning-Kruger kids — too incompetent to realize that they’re incompetent — loose on federal agencies, where they began firing workers without trying to understand what these workers do or why it might be important. These firings have been followed in several cases by desperate attempts to rehire the lost workers, who turn out to have been doing things like, um, securing the nation’s nuclear weapons. Now, Musk’s DOGE claims that it has already saved taxpayers tens of billions of dollars... last month it released what it called a “wall of receipts,” purportedly documenting some of the claimed savings. That document, however, turned out to be riddled with huge errors... Last week it released a revised, much smaller “wall” — but that version also turns out to be full of major errors... Imagine how a private business would react if it hired a supposed efficiency expert who quickly fired crucial employees while making grandiose claims about the money he’s saving, but kept releasing progress reports that were full of ludicrous errors. You wouldn’t keep him on; you’d have security escort him out of the building and immediately change all the locks. But Trump went out of his way to praise Musk, who is still wreaking havoc that goes beyond the immediate impact of the layoffs... Sooner or later, and probably sooner rather than later, important things are going to break.

DOGE moves to cancel #NOAA leases on key weather buildings

"One of the buildings is the nerve center for generating national #weather forecasts.

It was designed to integrate multiple #forecasting centers in one building to improve operating #efficiency. It houses telecommunications equipment to send weather #data & forecasts across the #US & abroad...

Elon Musk's #DOGE has been working through the #GSA to cancel #government leases"

An FDR-Style "State of the Union"

Imagining What He Would Say Today, versus Trump/Musk/Putin
davidpepper.substack.com/p/an-

"The actions of #Musk & his associates mirror those of the #economic royalists I warned about in prior years...

their dismantling of vital #government agencies & services and the bypassing of constitutional #ChecksAndBalances are not acts of #efficiency or savings, but attacks on the foundations of our republic."

Headline and editorial cartoon. Headline: An FDR-Style "State of the Union" Imagining What He Would Say Today, versus Trump/Musk/Putin by David Pepper Mar 04, 2025 Editorial cartoon: Trump is standing in front of a podium with a Big Mac on it. Sitting in state behind Trump are Elon Musk and Vladimir Putin. Trump is holding his tiny hands apart and saying, "The state of this union is this strong." Credit: Kevin Necessary
