No. The Boeing 747 was not designed for supersonic flight, though during testing, it was pushed quite close to the sonic speed: Tom Cole, a spokesman at Boeing Commercial Airplane Co., said original flight tests of 747s conducted in 1969 and 1970 took 747-100 models to speeds of Mach 0.99..
Likewise, people ask, can commercial planes break the sound barrier?
Modern aircraft can transit the "barrier" without control problems. Although Concorde and the Tu-144 were the first aircraft to carry commercial passengers at supersonic speeds, they were not the first or only commercial airliners to break the sound barrier.
Subsequently, question is, what aircraft can break the sound barrier? F/A -18 HORNET
In this regard, can a 747 do Mach 1?
A 747 is certainly capable of going supersonic. Boeing and other entities have tested it right up to the threshold of Mach 1 (around 0.98 or 0.99).
Has a propeller plane broke the sound barrier?
The idea is that the propeller does not break Mach 1 before the plane. The project was later abandoned because of the introduction of jet powered aircraft which could reach the sound barrier with relative ease.
Related Question Answers
Can a sonic boom kill you?
The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.Why are sonic booms illegal?
Within the United States, it is illegal to break the sound barrier. When you pass Mach 1, the plane travels faster than the waves itself and that move across the so-called sound barrier produces a large sound, which is the sonic boom.Why do we not hear sonic booms anymore?
Why don't we ever hear sonic booms any more? Noise abatement regulations halted supersonic flight (by civil aircraft) over U.S. land. The Concorde could still take off and land here because it broke the sound barrier over the ocean, but it's no longer in service.What is the fastest jet in the world?
With a clocked speed of some 100 miles per hour faster than its closest competition, along with a personal account of the jet traveling upwards of Mach 3.5, the Lockheed SR-71 Blackbird is the fastest jet on the planet — and it's not even a close race.Do the Blue Angels ever touch?
Two Navy Blue Angel jets touched during practice in Florida, Navy officials confirmed. The Pensacola News Journal reported Thursday that the midair incident happened Wednesday while the demonstration team practiced at Naval Air Station Pensacola, Florida. Only a minimal scratch was found, according to the News Journal.Does a bullet break the sound barrier?
Bullets break the sound barrier with boring regularity. The speed of sound is roughly 1125 feet per second at standard temperature and pressure (sea level). Even bullets from guns chambered in . 22lr, a relatively low powered cartridge, break the sound barrier with common ammunition loadings.Can you fly supersonic over land?
Since SSTs produce sonic booms at supersonic speeds they are rarely permitted to fly supersonic over land, and must fly supersonic over sea instead. Since they are inefficient at subsonic speeds compared to subsonic aircraft, range is deteriorated and the number of routes that the aircraft can fly non-stop is reduced.How loud is a sonic boom?
Sonic booms generate enormous amounts of sound energy, sounding much like an explosion; typically the shock front may approach 100 megawatts per square meter, and may exceed 200 decibels. When an aircraft is near the sound barrier, an unusual cloud sometimes forms in its wake.Which is faster 747 or 777?
Answer: The Boeing 747 can cruise at 92% of the speed of sound, Mach . A 777 engine may be equal to two 747 engines, but the wing is not designed to take such a large engine in one place.How fast is a 747 in mph?
The 747-400, the most common variant in service, has a high-subsonic cruise speed of Mach 0.85–0.855 (up to 570 mph or 920 km/h) with an intercontinental range of 7,260 nautical miles (8,350 statute miles or 13,450 km).How fast is the fastest plane?
Since 1976, the Lockheed SR-71 Blackbird has held the world record for the fastest 'air-breathing manned aircraft' with a recorded speed of 1,905.81 knots (2,193.2 mph; 3,529.6 km/h). That works out to a staggering 36.55 miles/58.83 km per minute.How fast is a 747 going when it lands?
Speeds vary according to performance, environmental conditions and weight but typically a fully loaded 747 on a normal long haul flight would take off from a typical length runway at around 160 knots which is 184 mph. A typical fully loaded 747 would be landing at around 25,0000kgs.How fast can a 747 climb?
A 747-8i or -8f is capable of climbing at a rate of 5600 to 6400 fpm, even if it's at 80% of it's maximum take off weight. The highest rate of climb the aircraft can sustain is around 8,000 fpm @ 60% MTOW or 10,000 fpm at 45% MTOW.Why do planes break the sound barrier?
The compressed air in front of the plane exerts a much larger than usual force on the plane. There is a noticeable increase in the aerodynamic drag on the plane at this point, hence the notion of breaking through the "sound barrier." When a plane exceeds the speed of sound it is said to be supersonic.Can a 787 break the sound barrier?
It appears that's a record for the Boeing 787-9 twin jet, which in the past has flown at speeds up to 776 mph. Commercial aircraft ordinarily can't break the sound barrier, because they're not designed to handle the sudden increase in drag and other aerodynamic effects associated with those speeds.Why are sonic booms so loud?
A sonic boom is a loud sound kind of like an explosion. It's caused by shock waves created by any object that travels through the air faster than the speed of sound. Sonic booms create huge amounts of sound energy. When an object moves through the air, it makes pressure waves in front of and behind it.What's the fastest commercial airliner?
The Lockheed SR-71 Blackbird long-range reconnaissance aircraft, used by the United States Air Force between 1964 and 1998, is the jet with the fastest speed record at 3.3 Mach (2,200 mph). Until now that is.Why do jets fly at 35000 feet?
The biggest reason for this altitude lies with fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.How fast is supersonic in mph?
Supersonic travel is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 344 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h.
