Analysis Of The Paper Helicopter Experiment

Decent Essays
The preeminent design of the paper helicopter experiment would comprise of the best mean and standard deviation of the overall measured data. An in depth comparison of the mean value and the standard deviation of each variable will be discussed in relation to a measure suitable for a longer flight time and a more accurate landing. These variables will be discussed relevant to the data and information gathered from our experiment during testing. The ratio of each helicopter will be discussed in order to replicate the appropriate wing length to base length ratio for the most successful design produced from the experiment.

The optimal design of a paper helicopter must consist of the best measured combination

The wing length of helicopter 3 is larger than its base length, implicating that the surface area of the rotor is significant to the apparent size reduction of a smaller base length (Diagram 8.3). It is evident in Graph 15.1 that the larger rotor length and smaller base length is more successful than a smaller wing length and larger base length. According to Barsalou from Minitab (2016), the optimal design for a paper helicopter includes that of a smaller base length and larger rotor length. The larger wing/rotor span is theoretically supposed to apply more upward lift, thus increasing the paper helicopters flight …show more content…
The distance from the landing position to the centre of the coin would be the measure for the accuracy of each design. A low standard deviation and low average distance is clearly the best combination in order to determine the design with the best accuracy and consistency. According to results from table 11.2, helicopter 5 had the most consistent and accurate landing positions. The design had a 2:1 size ratio on the other helicopters making it presumably the most accurate and controlled helicopter. The increased surface area allows the position of helicopter during its fall to stabilize and resist air pressure from different angles. This is because the larger wings/rotors are able to endure higher resistances and impede any forces other than air resistance and gravity that acts upon the helicopter. It was recorded that helicopter 5 has a standard deviation of 4.3 and an average landing position of 6.3cm away from the centre of the coin (table 11.2). This would suggest that the distances recorded for helicopter 5 is 4.3 standard deviations away from the mean. This indicates that the data is very consistent and considerably the best set of data out of the 5 designs because of the lower average. The design of every helicopter was modified from the original design, by increasing the rotor and base width by 1.8 cm. This therefore makes the surface area of the first

    We are testing how the amount of wings can affect a rocket’s flight time and think that the more wings there, the shorter flight time.” We were correct. The rocket with 3 wings had a flight time of 3.62s with 1 liter of water in it, and 1.29s with 2 liters of water in it. The rocket with 4 wings had a flight time of 3.78 seconds with 1 liter of water, and 1.5 seconds with 2 liters of water in it. So, the three winged rocket did have faster flight time, probably because it was less air resistance. The reason that the rockets performed so poorly with 2 liters of water in them is because that didn’t leave enough room for air, so not much air pressurized and the water didn’t shoot out fast enough.…

    The 787 Dreamliner uses a higher amount of composite materials than any model that has come before, made up of carbon fibre reinforced plastics and other composites. Composite materials are more capable of handling tension forces but less capable of handling compression. The use of composites also reduces fatigue and so reduces the need for maintenance. The Boeing 787 is made up of 50% composites, 20% aluminium, 15% titanium, 10% steel and 1% other. (6. www.boeing.com 30/10/14) The materials used in both the Airbus A380 and the Boeing 787 Dreamliner must be strong enough and maintained as efficiently as possible to overcome various stresses it will face during take-off, flight and landing.…

    These are explained as follows- The following interpretation can be made from above graphs for 100N load: 1. The graph 5.7 shows the variation in total deformation for following five designs (1, 2, 3, 4, and 5). The obtained result concludes that the design having the least total deformation is 5. The lesser variation in total deformation results in stability and higher strength. The design 5 is considered as best amongst all.…

    3D printed parts are lighter compared to the parts that were made of solid materials. The ability to do this with materials such as titanium can resolve the major obstacle called as “Buy-To-Fly” ratio. It is ratio between pounds of material needed to make one pound of flight quality material. This can be reduced by 50% and that can have a huge impact. Design process if often complex because they have parts like air ducts and jet engines that were limited by injection molding and subtractive constraints.…

    The next-gen air traffic control system has many different components. However, one of them stands out from the rest. That will be the Automatic Dependent Surveillance-Broadcast also known as ADS-B. The Automatic Dependent Surveillance-Broadcast system will help improve the tracking of aircraft and also help increase the efficiency of the entire air traffic system. The reasoning behind this is because it will allow tracking over areas without radar coverage, it will improve tracking of aircraft, and it will help pilots keep track of what is in the airspace around them.…

    Even though this is is a really good point about how reliable a Diesel engine is there are a couple other good and important reasons to why Diesel engines are more reliable. Diesel engines prove that they are more reliable, because they can run almost three times longer than a gasoline engine. According to trucktrend, "Gas engines only last 100,000 to 200,000, but Diesel engines last 3 times longer than that" (Schifsky). Diesel engines last longer because they are built better than a gasoline engine. Since diesels operate on compressed air you do not have to worry about carbon monoxide and unburdened hydrocarbons forming in the crevices of the cylinder walls like they do in gas engines.…

    The wings of the 747 also swept back at a thirty seven degree angle. This shape allowed for a faster cruising speed and also allowed the 747 to fit into existing hangars as it reduced the horizontal wingspan (Rummerman). One of the greatest challenges to ever face the 747 concept was the insufficient…
