Physics research helicopters

In conclusion, the purpose of this lab was to decide if the sizes of the paper helicopters would have an effect on their descent times. One theory was that if the size of the paper rotocopter increases, then their descent time will also increase.To determine the results of this experiment certain procedural steps were followed. Firstly all five of the rotocopter were cut out, and folded on the dotted line, the paperclip was used to hold the flaps on the bottom of the

The UH-1 Huey Helicopter has the ability to land on prepared and unprepared terrain. The helicopter is equipped with skid tubs instead of wheels. The aircraft is also capable of landing on both soft and hard surfaces. Just like all aircrafts, the UH-1 Huey Helicopters has the capability to land on hard surfaces like runways and flight line decks. In addition to being able to land on hard prepared surfaces, this aircraft can also land on loose surfaces like sand or gravel. With having skids in place of wheel, the Huey can land in beaches without worrying about the integrity of the landing gears. UH-1 Huey Helicopter also has the ability to land in the forest or the jungle with an opening in the

The helicopter was forced to crash land in the valley and now was 7 kilometers away from the

Next, there is a while loop that continues to run if the left encoder is less than the value of the number of revolutions multiplied by the counted ticks per revolution. After this, if the computed motor ticks are unequal between the two motors, the function is written to where the vehicle can adjust and correct itself if it starts to drift to one side. This is done by if-else statements in which each motor power is adjusted. Variables used in the driveStraight() function were used in the turnLeft () function as well. The function contains a turningTime variable, which is set to the inputted angle multiplied by 1000 and is divided by the inputted turning speed. Like the previous function, if-else statements were used to adjust each of the motors power to make a proper turning angle. At the end of the function, the command encoder.clearEnc(Both) clears both the encoders counted motor

The pilot taught Brian how to steer the plane and with Brian’s pryor knowledge he is able to keep the plane fling and turn it towards water

In theory, utilizing helicopters could relocate their forces fast enough to keep the enemy from conversing on any one unit. On the contrary, an American Force discovering an NVA unit would fix its position while the reinforcing battalion flew in to cut off the enemy's retreat and annihilate them (E-History, 2012).

One key battle that shows usage of helicopters was the battle for Quang Tri City. This battle was a part of the 1968 Tet-Offensive. The Tet Offensive was a surprise attack on key points on the United States in South Vietnam during the Vietnamese holiday Tet. It involved when 2 battalions of People 's Army of Vietnam and 2 Vet Cong battalions attack the East of the city of Quang Tri. The Army of the Republic of Vietnam was able to block them off before the whole city was taken. With ARVN reinforcement’s days away, US Colonel Rattan planned an attack to regain the city. That plan was landing airmobile forces by the enemy rear and communication lines

Things started to go bad for the rescue mission when two helicopters had to turn back due to mechanical problems. The rescue required at least six helicopters that is all the team now had. Upon landing at Desert One another helicopter damaged its landing gear. The mission now had to be called off. As one of the helicopters attempted to lift off it banked towards one of the C-130s on the ground striking the plane and both burst into flames. Eight military personnel were killed in the incident. Another rescue plan was started but quickly scrapped. The picture below shows the crash. The helicopters were left behind for fear they might also kick up a dust storm and topple onto the C-130s.

The purpose of this assignment is to work out a parachute design and investigate parachute’s drop time. Parachutes are designed to fall slowly so that the person can land safely to the ground, as shown in figure 1. Parachutes are big, but not heavy and have a larger surface area for air resistance like traps the air from escaping out of it. This is because the air pushes the parachute back up, but the force of gravity pulls the parachute to the earth.

Spectators gaze with wide eyes as the Shrike Commander screams to earth with both of the two engines out, the pilot must be out of control! Then, the aircraft pitches up and flies feet above the ground. The pilot then pulls up for a loop. The flight control inputs are flawless as a perfect circle shape is make in the sky. When the aircraft recovers, the pilot pitches up again and does a sixteen point roll. Still with no engines, the pilot turns to final approach for the runway and lands just on the left wheel. The aircraft then touches down both mains and comes to a haut. The pilot steps out of the beach craft and the crowds sees the most ah inspiring aviator on earth, Bob Hoover.

During the mission the TFR planed the mission as if the UH-60 will not get shot down. Before this mission on 21 September 1993 during the mission that captured Osman, TFG helicopter got fired upon by roughly fifteen rockets propelled grenade (RPG). Nevertheless if that was not enough upon previous weeks an UH – 60 was shot down even though it was flying 130, rooftop level and concluded that UH – 60 was vulnerable to RPG fires. With this kind of intelligence, the TFR could have changed the tactics upon approaching the target, but they did not. This is a great example of overconfidence bias, where they believed that the helicopter would not gotten shot down. Consequently, if TFR planed where the protection of the helicopter was one of the priorities they could have prevented the crashed, which was the cause by the enemies RPGs costing American lives. In lieu of orchestrating with the intelligence the TFR did not understand the enemies’ threat and plan the mission without an alternate means of action for the UH-60. Because of this, two of the UH-60 crashed in enemy territory, making the US forces to conduct rescue mission, this cost more time, resources, and Soldiers. Only if the planners of the TFR questioned their own methods and got out of their own mindset, they could have had different actions of approach. Therefore the RPG capability from the enemy, the size of the enemy unit, and different course of action during the fight, when the UH-60 was in trouble, lack of intelligent observation was the key causes all of this chaos. All of this intelligent, only if someone just took the time to think through and analyze the information, the TFR could have transmuted the course of action for this mission and maybe preserve Soldiers'

The accelerator rolls rotate at around 320 RPM to grab the crop from the feeder chains and the launch the crop into the rotor. The accelerator rolls are located on top and below the feeder house so they mash the crop between the interlocking rolls as the crop passes through. The goal of the accelerator rolls is to keep the rotor full with crop. This begins the processing and breaking down of the crop into clean

The United States Army began its aviation heritage in the mid 1920’s as the United States Army Air Service later turning into the United States Army Air Force. It was the aviation fighting force for the Army until 1947 when the United States Air Force was created and the Army was no longer legally allowed to conduct missions in the same manner as it did in World War II (WWII). It was in WWII that the Army saw the potential of Vertical Lift, however it was too late to make any effect on the war. The helicopter saw its first combat in the mountains and valleys of Korea. It was here that the Army was able see a significant change in combat due to this new piece of technology. U.S. Commanders were able to get real time updates to the

That’s exactly what happened earlier this month. Luke Aikins, an American skydiver with over 18,000 dives to his name, attempted this exact feat. ‘Luckily’ for him, he would have a 30mx30m net to catch him – still a miniscule area from a height of 7.6km. If he succeeded, he would be the first person to jump out of a plane at that height with no parachute or wingsuit. If he didn’t… well… we all know what would happen then. He was so high that when he first jumped from the plane, he required an oxygen mask just to breathe. The whole stunt would also be telecast with a 2 minute delay, just in case.

Since the beginning of recorded history, humans have always had a fascination with flight. Now that we live in a world where boarding an airplane and flying across the country – or even the world - is simply a part of everyday life, the wonder of flight has diminished for many. Despite this, physics students from all around continue to delight in the many physical forces that play a part in keeping these huge objects (like jumbo jets) from falling out of the sky!
