Which of the following is a stealth aircraft designed to be invisible to enemy radar?

Which of the following is a stealth aircraft designed to be invisible to enemy radar?

Reduced radar cross section is only one of five factors the designers addressed to create a truly stealthy design such as the F-22. The F-22 has also been designed to disguise its infrared emissions to make it harder to detect by infrared homing (“heat seeking”) surface-to-air or air-to-air missiles.

What makes a Stealth bomber invisible to radar?

To hide from radar, a stealth plane’s panels all slant nearly horizontally, so that there are no broad surfaces for radio waves to bounce sideways off of and return to their source. Stealth planes must not only evade radar, but heat-sensing missiles as well.

How are stealth planes undetectable?

The goal of stealth technology is to make an airplane invisible to radar. There are two different ways to create invisibility: The airplane can be shaped so that any radar signals it reflects are reflected away from the radar equipment. The airplane can be covered in materials that absorb radar signals.

Are stealth bombers silent?

But unlike a passenger jet or B-52, the B-2’s engines are buried inside the plane. This helps muffle the noise. The efficient aerodynamic design helps keep the B-2 quiet as well, because the engines can operate at lower power settings. The engine system also works to minimize the plane’s infrared (heat) signature.

Can the b2 break the sound barrier?

B-2 bombers have a max speed of Mach 0.95, or 630 mph, and are not capable of breaking the sound barrier.

Why are sonic booms visible?

A sonic boom is created when an object travels faster than the speed of sound. This is often called “breaking the sound barrier.” The visible part of a sonic boom is actually air that becomes squashed by sound waves.

Is breaking the sound barrier visible?

The breaking of the sound barrier is not just an audible phenomenon. In fact, Mach 1 can be beautiful. The visual counterpart to a sonic boom, which sometimes but not always accompanies the breaking of the sound barrier, has also been seen with Apollo 11 moon-landing mission rocketed skyward in 1969.

What happens when you break the sound barrier on land?

When the object has passed over the observer, the pressure disturbance waves (Mach waves) radiate toward the ground, causing a sonic boom. Then, just as the aircraft bursts through the sound barrier, the air is locally disturbed by the resulting shock wave and the condensation/vapor cloud disappears.

Has a 747 ever broken the sound barrier?

A China Airlines 747 may have broken the sound barrier in an unplanned descent from 41,000 ft (12,500 m) to 9,500 ft (2,900 m) after an in-flight upset on 19 February 1985. It also reached over 5g.

Is there a car that can go 1000 mph?

A new vehicle from the Bloodhound Project, called the SuperSonic Car (SSC), is built to surpass speeds of 1,000 miles per hour, according to CNN. In 2016, the makers plan to break the land-speed record in South Africa.

Has any car hit 500 mph?

WATCH: It’s hoped the jet-powered car will beat the land speed record! The Bloodhound supersonic car has reached a speed of over 500 miles per hour (mph)! The current record of 763mph (1,228km/h) was set 22 years ago, also by Andy Green, in the Thrust SSC car. …

Has any car hit 300 mph?

In 2005, Bugatti’s Veyron hypercar broke the 250-mile-per-hour barrier. In late 2019, The Bugatti Chiron Super Sport became the first production vehicle to ever reach 300 miles per hour.

Is 500 hp a lot?

It’s not even for most. 500 horsepower crosses a threshold. It’s at that level of power that you begin to feel real weight on your chest when you accelerate — like the steering wheel is trying to break free from your hands. The world around you starts to move faster than you can reasonably react to.

Is 300 hp a lot?

300hp, or horsepower, is not considerably significant. However, It’s plenty of power for most applications! For a sports car, 300hp is a great benchmark, showing that a car will be lots of fun. This means the engine is serious about performance, and likely consumes lots of fuel.
