The land-speed record, aka the fastest car on Earth, remains one of the benchmarks of technological development..
Can a Boeing 737 fly across the Atlantic
Low cost carriers are starting to compete on this market, most importantly Norwegian Air Shuttle, WestJet and WOW Air. … Norwegian Air performed its first transatlantic flight with a Boeing 737-800 on 16 June 2017 between Edinburgh Airport and Stewart Airport, New York.
Are sonic booms illegal
Within the United States, it is illegal to break the sound barrier. … Breaking the sound barrier leads to a sonic boom. And regulators have determined that people need to be protected from sonic booms. Planes produce sound waves when they travel.
What is the fastest a 747 can fly
The top speed for a 747 is about 570 miles per hour (mph), and this flight topped out at 825 mph.
Who broke Mach 3
Bell X-2 exceeds Mach 3, September 27, 1956. USAF Captain Milburn G. Apt became the first man to exceed Mach 3 while flying the Bell X-2 on September 27, 1956. Unfortunately the aircraft went out of control after making history and he was killed.
What is the fastest land speed ever recorded
Land speed recordThrustSSC, driven by Royal Air Force pilot Andy Green, holds the current land speed record at 760 mph set October 15, 1997.Ralph DePalma in his Packard ‘905’ Special at Daytona Beach in 1919.Dorothy Levitt, in a 26hp Napier, at Brooklands, England, in 1908.
How high winds can planes fly
Aircraft do have an additional limitation in terms of wind, and that is to open or close the aircraft passenger and cargo doors. Typically, the wind should not exceed 45 knots.
How does Prop size affect performance
Increasing the propeller size may reduce the cruise RPM for the same cruise speed but will also increase the load on the engine and therefore increase the fuel usage needed. In effect, you may reduce the cruise RPM but you burn the same amount of fuel and you increase the stress on the engine.
Why are afterburners so loud
Because they have lower bypass ratios. … Fighter jets are more concerned with instantaneous performance rather than fuel efficiency or noise, so they decrease the bypass ratio to achieve more total thrust. Also, fighter jets have afterburner, which is very satisfyingly loud.
Can passenger jets 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.
Is a sonic boom dangerous
Sonic booms due to large supersonic aircraft can be particularly loud and startling, tend to awaken people, and may cause minor damage to some structures. They led to prohibition of routine supersonic flight over land.
Does a bullet make a sonic boom
Most bullets make small sonic booms when flying through the air, which to our ears sound like a loud, distinct “crack!” For the Pentagon’s special forces, that makes it hard to be sneaky about what they’re shooting.
Do propellers break the sound barrier
In dry conditions, an aircraft needs to be moving at about 767 mph to hit the barrier. … Adjusting the length and width of the blades ensures that the propeller doesn’t meet or exceed Mach 1 before the aircraft itself. Delaying the onset of these forces ensured that the prop could operate at supersonic speeds.
Can an a380 break the sound barrier
In the air, the answer is no and yes. A modern aircraft such as the Airbus A380 flies at a cruising speed of about 900 kmh. … When an aircraft exceeds 1236 kmh, it “breaks” the sound barrier and creates a sonic boom that sets dogs howling and annoys folks below.
Has a car broken the sound barrier
Thrust SSC holds the world land speed record, set on 15 October 1997, when it achieved a speed of 1,228 km/h (763 mph) and became the first land vehicle to officially break the sound barrier.
Is Thunder a sonic boom
This is often called “breaking the sound barrier.” The visible part of a sonic boom is actually air that becomes squashed by sound waves. The thunder that a storm makes is also a sonic boom caused by lightning forcing air to move faster than the speed of sound.
What speed do planes land at
Big commercial airplanes generally fly in the 550-580 MPH range, but their landing and taking-off speeds are naturally going to be different. Most commercial planes take off at roughly 160 to 180 MPH, while landings take place at approximately 150 to 165 MPH.
Why are turbofans quieter than turbojets
Turbofan engines are inherently quieter than turbojets for a given level of thrust. … Turbojet thrust is developed solely by the turbine engine. Therefore, for a given thrust, the fanjet’s discharge contains less energy (but more mass) as it exits the engine, and so produces less noise.
Did Concorde have afterburners
After reaching Mach 1.7 they were switched off. Concorde was the first production aircraft to be able to super-cruise – maintain supersonic flight without afterburners, almost 30 years before the F-22. It was also the first production Fly By Wire aircraft and boasted many other firsts.
Is the sound barrier real
Today, we know that the sound barrier is the sudden increase in aerodynamic drag that happens when an object approaches the speed of sound — also known as Mach 1. It’s not a physical or solid barrier. The moment an aircraft’s speed exceeds the speed of sound, it is said to have broken the sound barrier.
Is the 787 Dreamliner safe
Many national airlines fly them, as do American and United. It’s important to note one very big difference between the 787 Dreamliner and 737 Max lines. Unlike the Max, since its introduction in 2009, no Dreamliner has ever been involved in a crash or serious accident.
How fast do you need to go to break the time barrier
Exceeding the speed of light, approximately 300,000km per second, is supposed to be completely impossible. According to Einstein’s special theory of relativity, it would take an infinite amount of energy to accelerate an object through the light barrier.
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.
What is the highest Mach ever reached
Guinness World Records recognized NASA’s X-43A scramjet with a new world speed record for a jet-powered aircraft – Mach 9.6, or nearly 7,000 mph. The X-43A set the new mark and broke its own world record on its third and final flight on Nov. 16, 2004.
How fast is a bullet in Mach
Supersonic is from Mach 1.3 to Mach 5, up to 1,700 m/s. Most, but not all bullet velocities in rifles run from about 1300 fps to 4000 fps, in SI units that would be a high of 1219.2 m/s. The Mach number in any media is the projectile speed compared to the speed of sound in that media.
What does it feel like to break the sound barrier
One does not feel anything apart from the pseudo-force due to acceleration while breaking the sound barrier , if they are inside a plane. Also , you can hear everything that happens inside the plane. This is because the air inside the plane is at rest with respect to the source of sound as well as the listener.
What happens when a propeller goes supersonic
As the supersonic speeds are approached (or exceeded locally), shock waves form over sections of the propeller blades- This significantly reduces the propeller efficiency while at the same time causes increased loads on the blade.
Can turbofans go supersonic
Turbofans can tolerate supersonic speeds because the intake creates constant flow conditions irrespective of flight speed. Efficiency for propellers and fan blades is highest at subsonic flow conditions.
Why do planes do not fly over the Pacific
The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.
Is there a sonic boom at Mach 2
It’s you standing still as the wave goes past you. … The wave speed for the sonic boom in air is the speed of sound. Whenever the plane is going faster than the speed of sound, it’s making a sonic boom that is always moving along with it. Nothing special happens at Mach 2.
What prop will make my boat faster
As a rule, a stainless-steel prop (assuming the correct pitch and diameter) will make your boat go faster — up to 2-3 knots on some boats. Stainless steel is stronger and can be made thinner, allowing more speed. Stainless steel also flexes less and keeps its shape at higher speeds.
Do the Blue Angels break the sound barrier
The elite F/A-18 Hornet jets used by the Blue Angels are built to fly at Mach 1.8, or nearly twice the speed of sound. … Still, said Blue Angels spokesman Lt. Mike Blankenship, “We cannot break the sound barrier.”
What is the fastest propeller plane in the world
The Tu-95 is the worlds fastest propeller driven aircraft in the world today. The Tupolev Tu-95 (Russian: Туполев Ту-95; NATO reporting name: “Bear”) is a large, four-engine turboprop-powered strategic bomber and missile platform.
Who died trying to break the sound barrier
Chuck YeagerChalmers H. “Slick” Goodlin, a test pilot who took the X-1 aircraft to near-supersonic speeds but became a footnote in aviation history when he lost his cockpit seat — and the right to shatter the sound barrier for the first time — to a young Chuck Yeager, has died. He was 82.
Why do aircraft fly at 35000 feet
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
What speed will break the sound barrier
U.S. Navy For an airplane to break the sound barrier, it must hit speeds of about 770 mph — when it does that a couple of things happen.
Can Planes Go 1000 mph
There are a number of different types of jet fighters, at least one bomber, and experimental aircraft that are capable of speeds in excess of 1000 MPH, but most not for very long nor very far.
What engine was in the P 38 Lightning
Allison V-1710Lockheed P-38 Lightning/Engine typesWith tricycle gear, twin booms and a centerline fuselage pod brimming with guns, the P-38 was powered by two 1,600-hp Allison V-1710-111/113 liquid-cooled engines driving three-bladed, 9-foot Curtiss Electric propellers.
How do you break the sound barrier
As the speed of the object increases to the sonic velocity (the local velocity of sound waves), these sound waves begin to pile up in front of the object. If the object has sufficient acceleration, it can burst through this barrier of sound waves and move ahead of the radiated sound.
What is the fastest street legal car
Veyron Super Sport 16.4The Veyron Super Sport 16.4 set the world record for fastest production car with a top speed of 267.857 mph, though the production version was electronically limited to 258 mph. The world record shows just how powerful its 1,200-horsepower engine really is.
Has a 747 ever broken the sound barrier
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.
Who really broke the sound barrier first
Chuck YeagerChuck Yeager is an American test pilot who was the first person to break the sound barrier — the point where a speeding object (such as an airplane) passes the speed of sound. Yeager made his history-setting flight on Oct. 14, 1947 in an airplane he dubbed Glamorous Glennis, after his first wife.
Is 3 or 4 blade prop better
A 3 blade propeller usually offers top speed performance while a 4 blade propeller provides maximum thrust and smooth cruising operation. Four blades have some features of their own, though. They often provide more lift at the stern which will help accelerate the hull, especially if it is stern heavy.
How do you stop Prop cavitation
In order to reduce the possibility of cavitation happening in marine propellers, a set of nozzles are placed on the hull of the ship directly in front of the propeller. These nozzles spray out compressed air over the propeller that creates “a macro bubble”.
