NACA used the F-100 Super Sabre to study supersonic stability, pilot workload, and sonic boom effects, turning early Mach-1 dangers into practical engineering rules.

The most striking difference for pilots was the cockpit. The DC-10 required a three-person crew: captain, first officer, and flight engineer. Its flight deck was dominated by analogue instrumentation, ...

The "universal shock absorber" revolutionizes power grid stability, providing a cost effective upgrade to current ...

Around midday on 28 April 2025, mainland Spain and Portugal experienced a catastrophic grid failure that disconnected 31 GW of ...

The patent-pending Universal Damping STATCOM (UD STATCCOM) is described as a ‘universal shock absorber’ for grids, intended ...

Quasi-periodic oscillations (QPOs) are a rare phenomenon in active galactic nuclei. They have been observed to occur at periods ranging from minutes to hours, days, weeks, and even years across the ...

ABSTRACT: In this paper, we study the forced oscillation properties of a class of fractional impulsive delay partial differential equations under the conformable fractional calculus definition with ...
