Flying lioats

IN the 1930s, flying boats became the largest, most comfortable passenger planes in the world. The spacious planes had hulls shaped like boats and floats under their wings. They could land and take off on the sea, as well as lakes and rivers.

In a time when aircraft engines were still unreliable, people thought flying boats were a safer wray to travel over the ocean.

Pan American Airlines called its flying boats clippers, alter the speedy sailing ships. They carried passengers to exotic destinations, such as the Far East and South America, at a time when few airports existed.

Flying boats were luxury cralt designed to compete with ocean liners. The biggest was Pan Am s Boeing 314 Clipper. A 106-foot-long-giant, it carried passengers at 174 miles an hour to Hong Kong or other cites in unequaled comfort. Yet as airports were built all over the world, flying boats were replaced by land aircralt.

image123ERY different from the flimsy biplanes of World War I, the fighter aircraft of World War II were tough, fast, and efficient. Aircraft had now become a primary means of waging war. Two nations, Germany and Japan, set out to dominate the world. In 1939, Nazi Germany began invading European countries. The German air force was called the Luftwaffe, or “air weapon.” Its Messerschmitt Bt 109 was a swift, fearsome fighter. More than 33,000 were produced.

German fighters and bombers terrorized Europe. Allied nations, including the United States, produced thousands of aircraft to light Germany and Japan. Fight eggs escorted bombers deep into enemy territory and battled in dogfights. Pilot skill was paramount. Spurred by war, aircraft advanced rapidly. Sleek new fighters flew at over 400 miles an hour and went 2,000 miles without refueling. By war’s end, the iirst

THE United States produced thousands of bombers during World War II. Among the most famous was the Boeing B-17. Called the Flying Fortress, this plane lived up to its name. It could carry over 17,000 pounds of bombs, and was armed with 12 machine guns for defense against enemy fighters. Later U. S. bombers included the Boeing B-24 Liberator and the enormous B-29 Superfortress. Many bombers were destroyed by enemy fighters and antiaircraft guns early in the war. The use of fighter escorts helped bombers complete their missions. Later bombers, such as the B-29, could fly to high altitudes beyond the reach of most enemy fire.

■ Their most powerful weapons were aircraft

carriers. Floating airfields, the huge ships known as "flattops” were 820 Feet long and carried up to 100 warplanes. Fighters and bombers took off and landed on their flat decks. The carriers allowed great mobility of air attack.

. Space Telescope

SPACE shuttle missions, which last usually one to two weeks, often launch equipment in space, retrieve it, or repair it. In 1990, the space shuttle DiWove/y launched the huge Hubble Space Telescope (HST) into Earth orbit. Called the “new window on the universe,” it was expected to give much clearer pictures of space than ever before because it would be orbiting outside Earth’s atmosphere.

Unfortunately» the first images from the HST were blurred because of a faulty mirror system. After over a year of training, crew in the space shuttle Епдшш(щг took off to repair the telescope in December 1993.

The astronauts worked on the telescope standing on the shuttle’s big robot arm, the Remote Manipulator System. They replaced corrective optical equipment, added a new camera, and other parts. By Januaryi images from the telescope showed the repairs had worked. Пае pictures were clear and spectacular! These images have helped scientists learn much more about the universe.

BY the summer of 1945, U. S. aircraft had sunk

over 700,000 tons of Japanese warships and destroyed over 12,000 Japanese planes. Yet the і Japanese would not surrender. Meanwhile, the I United States had built the largest bomber of the war, the B-29 Superfortress. It had also secretly developed the atomic bomb.

image141"In August, U. S. president Harry Truman decided to use the bomb to end the war and continuing loss of American lives. He ordered the flight of the B-29 Enola Gay to carry and drop the atomic bomb on Japan. Called Uittle Bov, the weapon was a 9,/ 00 pound uranium bomb. On August 6, 1945, the bomb was dropped over the Japanese city of Hiroshima. In seconds, the blast smashed the city and killed thousands of people. Yet Japan still did not surrender. Three days later, a 10,000 pound plutonium bomb, called “hat Mari,” was dropped from a second B-29 over Nagasaki. This explosion killed thousands more. On August 15, Japan tlnally agreed to surrender.

History Fact: Lethal Weapon

The blast of the uranium bomb dropped on Hirosh ma was equal to about

20,0 tons of TNT.

Meeting Міг

N June 29, 1995, the space shuttle MLntti* made a historic flight. It successfully met and docked with the Russian space station Mir, or “Peace,” orbiting 245 miles above the Earth. Shuttle mission commander Robert L. Gibson steered Atlantis into docking position near Mir. Both were hurtling through space at 17,500 miles an hour. Gibson had to slow Atlantic down and very carefully maneuver it to avoid a crash. I Ie also had to act quickly enough to catch and lock onto the space station before it drifted beyond reach. He performed the maneuver perfectly.

After docking, uxz AJikintitt crew floated through a connecting tunnel to enter Mir and met the Russian cosmonauts inside. For five days, the two crews socialized and worked on experiments together. This was the first ol several visits of space shuttles to Mir. The two countries that were once fierce rivals in space have since done much to cooperate with each other to increase space knowledge.

Docked in space, the shuttle Atlantis and Mir space station float in orbit. This picture was taken by a Soyuz ferry spacecraft in June 1995. Such joint missions helped pave the way for work on the new International Space Station.

Fun Fact: Long Trip

The record time for living in space is held by Russian doctor faJgw Pnliakov. He stayed on Mir a total of 438 days! From his experience, scientists learned much about how the human body adapts to long periods in space.

image242Maneuvering in Space

Steering the shuttle in space requires two systems. The orbital maneuvering system (OMS) engines slow the shuttle down and move it up or down. Then 44 rocket thrusters on the craft’s nose and tail can be fired to change speed or direction.

The Russian space station Mir passes over New Zealand. In orbit since 1986, the station was replaced by the new International Space Station in 2001. Mir was abandoned and allowed to burn up in the atmosphere as it fell back to Earth.

The Sound Barrier

T

OWARD the end ol World War II, aircraft entered a new age ol speed. In 1944 and 1945, German pilots flew the first jet-powered lighter in combat, the Alesserschmitt Ale 262. Allied pilots were astonished to spot it zooming over 100 miles an hour laster than any Allied lighter, and with no propellers!

Alter the war, many pilots tried to fly taster th an the speed of sound. On October 14, 1947, American test pilot Chuck Yeager flew an orange bullet-shaped plane with a rocket engine. It was the Bell X-l, designed to break the sound barrier. Carried up by a B-29 mother plane to save fuel, the X-l was dropped in the air. Yeager lired the rocket engine anil pushed the plane to over 700 miles an hour, past Alach 1 —the speed ot sound. The plane bulleted, then blasted through the sound barrier. Once past Alach 1. it was so smooth, said Yeager, “Grandma could be sitting up there sipping lemonade.”

‘Suddenly the Alach needle began to fluctuate…then lipped right off the ocale, I thought / wao oeeuig thi ago! We were flying ouperoonic:

Charles “Chuck" Yeager (1923- )

A World War II fighter pilot. Chuck Yeager became an Air Force test pilot after the war. He made history as the first person to break the sound barrier in 1947. At the time, many believed a plane flying through the sound barrier would be ripped apart by the shock wave. Yeager later rose to the rank of brigadier general.

Famous Flight

On October 14,1947, the Bell X-1 accelerates and races toward the sound barrier. Flying at 43,000 feet, pilot Chuck Yeager became the first person to travel faster than sound, at Mach 1.06.

image144

< MaCHMETER

Mach numbers measure the speed of an aircraft in relation to the speed of sound. Mach 1 is the speed of sound, which increases with temperature because sound travels faster in warmer air. At

40,0 feet, Mach I is 657 miles an hour.

► The Sound Barrier

Moving through the air, a plane makes pres­sure waves. When the plane catc hes up with its own pressure waves, they bunch together, building into a shock wave. Passing the speed of sound, the plane flies ahead of its pressure waves, forming a cone-like shock wave.

Frank Whittle (1907-1996)

Frank Whittle was a young British pilot who patented the first turbojet engine in 1931. It used a jet of hot gases instead of propellers. Soon after, German engineer Hans von Ohain invented a similar engine Germany first produced a jet fighter in 1943, the Messerschmitt Me 262. A year later, the British began flying a jet fighter, the Gloster Meteor. Its engines were based on a Whittle design.

The construction work will continue lor five years. The astronauts will spend many hours of spacewalks assembling the station. They will get help from a large robotic arm made in Camida and possibly a flying robotic “eye” that can circle around to inspect the huge station.

In the finished station, scientists believe the absence of gravity will allow them to do experiments not possible on Earth. They hope to develop new drugs, new ways to treat and prevent diseases, more powerful computer chips, stronger metals, and better weather forecasting systems. Life on the ISS will also provide knowledge for future space travel beyond Earth’s orbit.

Korea and Vietnam

HE Korean War, from 1950 to 1953, was the first con­flict where jet fighters battled. The United States fought Communist forces in Korea. In the short time since World War II, jets had made propeller lighters obsolete. Faster speeds required pilots to react more quickly. The opposing planes could now close in over 10 miles in 30 seconds. The U. S. F-86 Sabre Jet and the Russian-built MiG-15 were the primary adversaries in Korea. Reaching speeds of nearly 670 miles an hour, the jets clashed in a famous zone known as "MiG Alley.”

From 1961 to 1973, the United States again fought Communist forces, this time in the Vietnam War. U. S. bombers dropped more tons of bombs in ill is war than both sides dropped in World. War II. I lehcopters played a critical role in Vietnam. Powerful helicopter gunships attacked the enemy and transported troops and supplies to the steamy jungle battle grounds. Helicopters also zoomed in to rescue wounded soldiers and downed pilots from behind enemy lines.

image149WARS over the last decades have greatly changed

and advanced military aircraft. The development of more sophisticated technology in radar, navigation, and weapons systems has produced faster, stronger, and more complex jet fighters and bombers.

Aircraft carriers have also changed. Jets are heavier than propeller aircraft. They require the boost of a catapult, like a giant slingshot, to launch them from the carrier deck. Carriers now have a catapult officer in charge of launching, called a “shooter.”

In a launch, a catapult hurls the plane from a standstill to a speed of 200 miles an hour in the air. Strong arresting cables on deck help the jets land safely. The jets have a tailhook to snag the cables as they kind.

Modern Fighters

TODAYS jet Fighters are among the fastest planes ever built. The F-16 Fighting Falcon, for example, can fly at more than twice the speed of sound. Alodern fighters use “fly by wire” flight. This means physical cables no longer pull on control surfaces su ch as the rudder. Instead, computers send signals along electric wires to motors that move control surfaces.

To increase speed, supersonic fighters today have streamlined bodies with pointed noses and swept-back or arrow-shaped wings. Some have ultra-thin wing edges to reduce drag and cut through air easily at high speeds. To withstand the scorching heat of supersonic speeds, the planes have "skins” of heat-resistant metals such as titanium.

Most fighters intercept and attack other aircraft. They may also attack ground targets. Pilots today locate targets electronically and fire deadly radar-guided or heat-seeking missiles. Modern fighters can cost up to $50 million each! MucJj of the cost is for electronic radar, flight, and navigation systems.

Sweeping down from the sky, an A-10 Thunderbolt II dives to attack. Designed to support ground troops, it can fly low and slow to destroy targets such as tanks with guns and missiles. The A-10 served in rescue missions during the GulfWar.

One recent design idea for a reusable spacecraft was the X-33, or VentureStar

Based on the "lifting body," it would lift off in an upright position, orbit, then return to Earth and land belly-down on a runway.

Another design was the X-37. It would be launched into orbit from the space shuttle. It would work in orbit, then return to Earth by its own power.

The X–43 was a plane designed to launch spacecraft into orbit. Known as the “Hyper X, th is plane would fly at "hypersonic" speeds, many times the speed of sound. A “scram-jet engine would allow it to use oxygen from the air to burn fuel, instead of using costly rocket fuel. The Hyper-X could launch craft into space at a tenth the cost of the rocket-propelled space shuttle. In coming years, scientists will continue research to develop new experimental concepts.

4 Hyper-X

In this artist’s concept, the X-*3,or Hyper-X research plane, roars up towa’d the fringes of space. Such planes, resigned to fly many times tne speed of sound, may one day oe usee to launch vehicles into space orbit.

►x-33

The X-33, or VentureStar, flies in Earth orbit in this artist’s concept. It is one of many ideas for reusable vehicles to lower the cost of space travel. It would take off like a rocket, orbit, and land horizontally, like an arpiare.

Fun Fact: Split-Second Timing

The fastest "air-breathing," wingec aircra’t today, the SR-71 Blackbird, travels in soeeds measured in tens of miles-per-minute. Hypersonic p’a^es like the Hyper-X may travel in speeds of miles-per-second!

This art shows how the Hyper-X would be launched, riding on a rocket uncer the wing of a B-52. Dropped at 43,000 feet, the rocket would boost the Hyper-X to

100,0 feet, then fall off. The plane would fly on by its own power.

Testing, Testing

Scientist Vince Rausch holds a model Hyper-X mounted on a rocket in a wind tunnel. Wind-tunnel tests show such a plane could fly to Mach 10 to reach space. In an artist’s concept (right), a Pegasus rocket lifts a Hyper-X on its nose.

In this imaginary scene, the X-37 is ready for launch from the payload bay of a space shuttle, Aoout half the length of the shuttle, this craft would orbit up to 21 days, performing experiments. lt would then return to Earth on its own.
