a stealth plane has the normal components of any other aircraft. the main difference is the exterior design of the aircraft. a stealth plane \s body is made at high angles to help deflect enemy radar. they also use radar absorbant paint so the radar pick up is nil or similar to that of a small bird.
Stealth aircraft are made so they don't show up on radar very well, or at all. This is important if you're going out to blow something up and don't want to be seen. Commercial aircraft could not be stealth aircraft because you really need to be able to see one on radar. Air Traffic Control uses radar to detect aircraft in its area, other planes use radar to detect you in the sky...having a commercial plane that couldn't be seen on radar would be very bad. - - - - - the difference is like police and thief.
The modern B2 stealth bomber uses a skeleton of standard aircraft aluminum. Components such as the engines, cockpit, and fuel tanks are made of a variety of materials: some steel, some aluminum, and variety of "standard" composites. The skin of the aircraft consists of the stealth material, which is a top-secret non-metallic composite compound. In addition, a special radar-absorbent paint-like substance is spread over the entire exterior surface (except the windscreen), to seal up the aircraft and insure than to panel or fasteners are exposed (as they would significantly hurt the "stealthiness" of the aircraft).
Conventional aircraft materials, primarily light alloys or aluminium.
All modern aircraft are made from a variety of materials, aluminium being the most prevalent.
Because smart engineering people designed them and chose the materials to make them as safe as they can.
Aircraft propellers can be made of wood, steel, aluminum, or composite materials such as fiberglass or carbon fiber.
Smart phones are made of metal and computer soft ware
Smart materials can be found in a variety of objects such as self-healing materials in phone screens, shape memory alloys in eyeglasses frames, and piezoelectric materials in sensors and actuators. In addition, self-cleaning surfaces and materials that change color in response to stimuli also utilize smart material technology.
They fly just the same as any other airplane. The only difference being they are made of materials that do not give a big radar image.
The first known instance of using smart materials can be traced back to the work of Pierre Curie and his discovery of the piezoelectric effect in 1880. This effect demonstrated the ability of certain materials to generate an electric charge under mechanical stress, laying the foundation for future advancements in smart materials.
