Metal Earth F-15 Eagle. I love to assemble model.  I have purchased models laser-cut from a single 4" square sheet of steel.  Pop out the pieces, bend the tabs  and assemble it. Finally my model is ready to showcase. I have enjoyed it. This model depicts the McDonnell Douglas/Boeing F-15 Eagle tactical fighter,  which remains undefeated in air-to-air combat. The speedy, agile twin-engine F-15 has been in service with the U.S. Air Force since 1974.

You might have some question like.... How can a jet engine work when it rains or snows? Wouldn't the water put out the flame inside? How is water removed from a jet engine in rainy conditions? Does rain or snow ingestion affect the efficiency of a jet engine? Answers are here... As we know a jet engine works by compressing incoming air,  mixing it with fuel, igniting that mixture, and exhausting the high-pressure gases to  produce thrust. The initial compression is accomplished through a series of rotating  blades called compressors. After jet fuel is added through a fuel injection system, the  mixture is burned in a combustion chamber. The exhaust moves through another series  of rotating blades called the turbine that powers the engine and finally through a nozzle. Simple Jet Engine The biggest danger posed by forms of precipitation like rain, snow, ice, or fog is an engine flame-out. A flame-out is defined as a loss of engine power that is not caused by a mec...

Why are the stabilizers on planes like the F-18 and F-22 slanted? The tail configuration is usually referred to as canted vertical tails, since the vertical stabilizers are canted away from being 90° straight up and down. As illustrated in the below photo of the F-18 Hornet, this design has become increasingly common on modern military aircraft. Canted vertical stabilizers on the F-18 Other well-known examples of this trend include the F-22 Raptor, F-117 Nighthawk stealth fighter, and F-35 Joint Strike Fighter. The feature traces its roots back to the 1960s when canted tails were incorporated into the SR-71 Blackbird and its predecessors, as shown below. Canted vertical stabilizers on the SR-71 Lockheed designers included these canted tails based on early research into stealth technology. As far back as the 1940s, engineers had realized that perpendicular surfaces, like vertical tails, generated strong radar returns. By canting the tails away from 90°, the radar cross-section (RCS) of ...
