Pyotr (Petr) Yakovlevich Ufimtsev (Russian: Пётр Я́ковлевич Уфи́мцев; born 8 July 1931) is a Soviet and Russian electrical engineer and mathematical physicist, best known for his pioneering work on the physical theory of diffraction (PTD), which laid the groundwork for modern stealth aircraft technology.
Stealth aircraft are still vulnerable to detection while and immediately after using their weaponry. Since stealth payload (reduced RCS bombs and cruise missiles) is not yet generally available, and ordnance mount points create a significant radar return, stealth aircraft carry all armaments internally. As soon as weapons bay doors are opened ...
Salisbury screens operate on the same principle as optical antireflection coatings used on the surface of camera lenses and glasses to prevent them from reflecting light. . The easiest to understand Salisbury screen design consists of three layers: a ground plane which is the metallic surface that needs to be concealed, a lossless dielectric of a precise thickness (a quarter of the wavelength ...
China's J-35A isn't its only new stealth aircraft in the works. Two prototypes of stealth fighters were seen flying in broad daylight in recent days and emerged on social media.
The Northrop Tacit Blue is a technology demonstrator aircraft created to demonstrate that a low-observable stealth surveillance aircraft with a low-probability-of-intercept radar (LPIR) and other sensors could operate close to the forward line of battle with a high degree of survivability.
The other is the fifth-generation J-20 stealth combat aircraft, which was commissioned in 2016. The US has the F-22 Raptor and the F-35 Lightning II in this category of stealth fighter aircraft.
