the Science of Flight
США
Добавлен 16 май 2018
Since the beginning, man had looked to the sky only to have remained earth-shackled. Aerospace engineering changed all that in a very short 100+ years. The airplane has come a long way since the 1903 Wright Flyer and aerospace engineering along with it. If you look at a modern-day fighter jet it’s no wonder that nowadays aerospace engineering curriculum can be a daunting task. This leads to 19 credit hour semesters being the norm, fast pace classes, missed content, less interactive lessons, lower comprehension due to shorter discussions, and never enough time to read the textbooks. Combine this with thick accents, difficult concepts, and professors who care more about research than teaching and engineering education turns into a game of stamina instead of a game of wit. At the Science of Flight we believe that excellence in engineering starts with excellent education and tSoF is dedicated to improving aerospace engineering education for the student as well as the working professional.
Top Down View of Orbit (Tutorial 5) | GMAT (NASA's General Mission Analysis Tool)
In this video, I show you a quick trick on how to get a top down flat orbital plane view of an elliptical orbit. This allows you to see the true shape of the orbit undisturbed by the location of the camera. The tool that is used in this video for simulation is NASA's General Mission Analysis Tool, or "GMAT", freely available to the public.

Thanks a lot for the explanations. What is the unit of the chord length used in Xfoil's Re formula. When you say a chord of 0.5 and a chord of 1, what unit is that in ? I presume it is in meters.
Hi. I have a question about datcom. Does it have pre calculated aircraft data like coefficients for cessna 172?
I am struggling to change the Ncrit number in the input file... any tips?
starting an internship at a defense company, this helped a lot!
Automatic subtitling has not decided yet whether it's named X-well, X-boil or X-coil 😆Thank yous so much for this serie of video!
Hi appreciate your videos. I still need some help: I am running a lot of aseq analysis at different Ma and Re automatically. Sometimes the analysis does not converge which is not a big problem. However, if that happens, there is no line for this AoA in the output file. I would like to have a line for that showing the result of the last iteration step or at least NaN or something. Is that possible?
hey, cool video. I have a problem. Every time I plot something on PltLib, it shows the first plot, but whenever I try to plot again using pplo, it doesn't get updated, it is stuck with the same plot. I can't even close the PltLib tab. I would have to close Xfoil to do that. Any solution to this? Thank you.
Thank you enlightening video.
Great work!! As this triggered my interest, I tried exploring the software more. ruclips.net/video/jvF7rSYQ8WI/видео.html at this time, I had defined my epoch and tried changing to different cartesian coodinate system. The values of the cartesian parameters keeps changing, does that mean that those values are for respective coordinate system for the same epoch? Please clarify.
Helpful for sure, but bro PLEASE get rid of that music. I'm watching at 1.75x speed and I feel like I'm playing crab champions
How precise the location of 2nd burn initiation has to be? Does it have to be exactly at the oposite side of the 1st burn or there is a room for error?
When I right click on the ReportFile, I can only choose Open Close and Clone. There is no option for renaming. Any thoughts?
Hi there my sensor values are very high 300-700 am I doing something wrong? Regards..
thanks for the video. but can you teach me how to determine the position of maximum pressure , the value of maximum pressure and the local velocity
is there an existing script to calculate a Hohmann transfer to mars at a specific landing site or close to one?
It would tremendously help if you also show what you are explaining at that moment.
Very well paced thanks

excellent video! music is not necessary though
how to trajected to lunar ?
Hello! Thanks for the video very much. It is very informative but whenever I try to change the no of panel nodes i get the message "input not recognized". Cn you please tell me how yo overcome it?
So I tried to discover gmat today on my own with the help of tutorials and had some difficulties through the process. Unfortunately there are not many resources about gmat on internet. I am writing this comment so if anyone else makes the same mistakes I did, it will help them. First I wrote 700 km for the sma which doesn't make any sense because the earth's radius is around 6300 km but I didn't realize it and gmat doesn't warn unfortunately. Then I tried to find the contact time with the ground station and could not get any results, lost a lot of time trying to figure out the problem. It was another stupid mistake I realized later. I wrote 1200 for the altitude of ground station thinking it as meters, apparently the unit is km and my ground station was higher than the orbit itself 🥲 So my friends be careful with the small details because gmat doesn't give any errors
sad to see this website is no longer active
help I can't get the light to turn on ? Any advice
too detailed man, thank you so much
People don’t be stupid, go buy a vacuum chamber and put a rocket firework in there and you’ll see it won’t work.
We have it does work. You think the 100-year old Tsiolkovsky Rocket Equation is untested all this time?
These videos are amazing you need to continue!!
Thanks so much for this amazing video
Please do more videos on calculationsss
Thanks for this video. You are so clear !
Chiarissimoooo grazie per questo contenuto
hats off to the videos, they are very informative and precise.
when i run the simulation it shows the error Solver subsystem exception. Can anyone help
Commenting for RUclips algorithm

Nice Tutorial, it would be more beneficial if you make MSES multi element airfoil Tutorial.
Thanks a lot. But I looks like your website is broken. I can't access, please fix it
The anvil example was excellent for my brain. Very intuitive, thank you.
Just Look at the equation for thrust: F = (m_dot • V_e) + (p_e - p_o) • A_e Where: F = Thrust m_dot = rate of mass flow of exhaust V_e = effective velocity of exhaust p_e = exit pressure of exhaust p_o = ambient pressure What this equation says, is that the thrust force generated will come down to the amount of mass you can move at a high rate, and how efficiently it’s generated. If you look at the terms to the right of the addition sign: (p_e - p_o) • A_e This relationship shows that, given the same exit pressure value, a larger ambient pressure value will yield a smaller product than would a lower one, since it’s subtracted from the exit pressure value in the equation. So what is really “required” for efficient thrust production from a rocket engine, is a large *difference* between the exit pressure of the exhaust and the ambient pressure. Plug-in whatever values you want for the other variables and solve for p_o = 0 🤷🏼♂️
You lost ALL of them at "equation"
Thank you for this video because if not i would of been imposible to use the arduino kit
You should make MSES tutorial as well, very informative explanation
Man, what a relief! I'd used to work with xfoil/mses in that way back in college, but I did not touch dos-based interface .exe ever since, so... forgot all about the details. Thanks for refreshing my memory!!
bro... help
How to slow down animation speed to really see what it is doing??
The top blue back and forth buttons alter the animation speed.
I'm using XFOIL through python for iterative calculations and I need some way to save the cases calculated to load them later to make xfoil calculate new solutions based in the previous ones. This would be easier if python keeped xfoil open during the whole operations but then I couldn't extract the data calculated to set the new parameters to introduce them in xfoil. I'm a little bit desperate as there's almost no information of XFOIL in Internet (sarcastically every other airfoil analysis software is based on xfoil), you're the best source of information. Thanks for your help!!
Nevermind I got it, the solution was in learning how to use the pexpect or wexpect module as the subprocess module doesn't keep xfoil open. It is considerably slower but effective.
Thank you this was awesome! I've been wanting to play around with software like this after being introduced to STK. I love the pace you taught at in the video. I'll be watching the rest of your tutorials!
that’s amazing, thx for the explanation 🙏🏻
I used 2 of the 3 widgets as spacers, because the Arduino doesn't fit flush.
NASA's own documents even say rocket propulsion won't work in a vacuum, that's why they have been working for this long to figure out an alternative 🤣
- "NASA's own documents even say rocket propulsion won't work in a vacuum" That is a flat out LIE. My company tests rocket thrusters IN A VACUUM here on earth and we verify that they produce the thrust predicted by the 100-year old Tsiolkovsky rocket equation. We then put those same thrusters on REAL spacecraft, launch them to space and TEST THEM THERE TOO. Stop spreading lies on the internet.
@Pounder I am embarrassed for the entire human race because there are still people as stupid as YOU that are allowed to procreate.
Mark Wells - I am calling you a liar. Stop lying.
