The plane of today is North American F 107. The North American F-107 was North American Aviation’s entry in a United States Air Force tactical fighter-bomber design competition of the 1950s. The F-107 was based on the F-100 Super Sabre, but included many innovations and radical design features, notably the over-fuselage air intakes. The competition was eventually won by the F-105 Thunderchief, and the F-107 prototypes ended their lives as test aircraft. This is a supersonic fighter aircraft, the mach number is up to 2. And as we can see, it really has a very unique design, like the intakes is up on the top of the plane. This design is very interesting, but not very helpful that the intakes increase the drag during the flight.
This past Saturday was a historic day for the men’s rugby team. For the first time in a long time they were the highest scoring team for the week in their division. Saturday’s game against California University of Pennsylvania, CUP, closed to a very lopsided 53-22 victory for Lehigh.
The weather for the match was wonderful with it being sunny and warm with the occasionally breeze rolling by. The game started off quickly with CUP scoring within the first few minutes of the first half. Afterward, CUP was able to hold Lehigh on their end of the field for several minutes before Lehigh was able to equalize.
After CUP scored again, Lehigh was again able to equalize and also make the two extra points which put them ahead. From this point on Lehigh scored try after try. Avery Black, inside center, had a hat trick with 3 trys in the match.
As the game wore on it was clear to see that CUP, having succumbed to both fatigue and frustration, began to play haphazardly with more fouls called on them towards the end of the match. At one point tensions were high as there were a series of illegal tackles made by both teams with only a few minutes remaining. Fortunately, nothing more came of it than the referee stopping play.
All in all it was fun match to watch. The Lehigh fans were finally given a good showing at home against a very competitive team. Results for the men’s rugby team can be found here.
So on Friday, the Rossin Junior Fellows Society (RJF) held the Broughal Engineering day in Packard Lab. The 8th grade classes from Broughal Middle School came over around noon and we split them into teams to do some engineering projects. The two projects were making a tin foil boat, which would be put into water and then filled with pennies, and to create a bridge out of tape, marshmallows and spaghetti. The students had a lot of fun with the projects and they got to hear some background information for why we were having them do those specific projects. We talked to them about suspension bridges, trusses, and about boats. All in all, it was a pretty productive day.
A few weeks ago I changed my work-study job to something a little bit closer related to my major and what I would like to do in the future. It is a position in which I am working with one of Professor Harts, whom I have talked a lot about, graduate students. What he is doing is making a gun launched areal surveillance drone for Keystone Automation. Right now, as a junior, I do not have a lot of knowledge of machine tools and of Solidworks, a 3D design software, to be of much help. However, the graduate student that I am working for is having me do odd jobs and is teaching me how to use machines.
The second week of class he had me make one working trainer aircraft from two broken ones. I did this so that he can use it to practice flying without using the drone. Below are some pictures of the trainer. Now if you notice, the wings are not attached. There is a screw that allows them to be easily swapped out so I did not put them on.
Two weeks ago he had me learn Solidworks so that I can help in modeling things. Last week, he showed me how to use the lathe. He needed some screws made so he figured it would be a good opportunity for me to learn.
I am very happy that I have found this new work-study job. I can now start using my hands and start building things.
University Productions yesterday put on a great live music event on the Front Lawn featuring the best student bands our school has to offer. The music ranged from Foggy Goggles’ modern jazz to Steel City Sunrise’s folk rock. Not only was there free live music but free pizza and soda as well. It made for a very fun few hours where I and many other students were able to enjoy a fading summer night while appreciating the many, hard-working student bands on campus. Click here to see a sample of Steel City Sunrise playing their original song “French Girls.”
Today we will have Cessna 172, which is the most popular and most produced aircraft in history. Cessna 172 is a civil utility aircraft developed from Cessna 170, manufactured by Cessna Aircraft Company. There have been more than 43,000 units built until now and it is still in production. The unit cost was $8,700 in 1956 when it was first introduced and is $307,500 now. It is a low speed aircraft with a speed of 188 miles/hr, and the airfoil it has is NACA 2412 wing section.
There are about 20 variants of Cessna 172, such as
In my whole entire first year of school here I never once saw mussels in Rathbone. I lived in Lower Cents too, so I ate there pretty much every day for months and months. You can therefore understand the enthusiasm I felt when I saw this surprisingly tasty dish at Community Grill in Rathbone a few nights ago. I personally love seafood so for me it’s one of those things you really miss about being home. Hopefully they’ll have that dish again or, if I’m lucky, they’ll have other new surprises in store.
