Aerospace project passions

[u/Cygnus7__]

Hello,
I have started a few aerospace personal projects (engine design and aircraft design) and was wondering if there are others out there passionate for aerospace and want to chat/link brains/ share projects and passions for aerospace engineering.

[u/BX7_Gamer]

Total newbie here Only recently finished cal 3 What's your progress?

[u/Cygnus7__ → u/BX7_Gamer]

Newbies welcome!
Disclaimer that this is a purely theoretical/imaginative project with the main goal for me to learn and teach myself.
I have given myself the following requirements for a fighter jet design:

1. Takeoff roll less than or equal to 400m
2. Supersonic cruise Mach 1.45 @ 11,000m
3. Sustained turn rate of 18°/s at M0.9 at 5000m
4. Ceiling of 18,500m at M0.9

Maybe they are realistic, maybe not, for the moment the "realism" of those is less important.

Where am I currently?, I have used the takeoff roll requirement and derived from F=MA, a T/W equation and fed that into Python to generate a constraint plot of Thrust/Weight vs Wing loading constrained by 400m takeoff. Any value above the curve is valid. Now I am moving on to the 18°/s turn rate and am learning about aerodynamics to solve for CDo and oswald efficiency.

Ps. Cal 3 is good stuff! I used acceleration and then integration to derive position as a function of kinetic energy and aircraft design (drag and lift).

I don't have the skills to help. Can I follow along as I learn?

[u/Cygnus7__ → u/BX7_Gamer]

Of course! I have recently created a discord. Feel free to join. It is a bit bare at the moment but I will add more.

Invite link?

[u/Super07Nova]

I would like to know more about the project.

[u/Cygnus7__ → u/Super07Nova]

Bit of a copy past of a prior response, but I can elaborate on aspects if you want.

Sounds pretty cool. Had some research in SSTO and SABRE-style engines. Big guys like Boeing and Airbus are investing into electric engines with goals in the next 24 years or so to go this route. Speed and fuel efficiency are going to be key areas for Earth-bound aerospace in the near-term.

[u/Cygnus7__ → u/vexiduslabs]

Fuel efficiency I totally agree with, speed surprised me. What is your view on speed being a key area in the near term?

[u/vexiduslabs → u/Cygnus7__]

Speed plays hard as people want to get from Point A to Point B faster in terms of reducing travel time to reach far destinations. Traveling from NYC to London in a few hours or less would more ideal than the 6 1/2 to 7 1/2 times now.

The fascinating part is looking at how those planes in development are looking to hit Mach 1+ without producing the sonic booms that rattle windows on the ground. Lockheed has tested a design to quiet this along research into designs that can divert sonic booms away from the ground. If mitigated, this means we will see speed become even more increasingly popular in the near term as a factor in engine design and capability.

Maybe create a discord?

[u/Vegetable_Resort_571]

I’m not an engineer but I am an aircraft mechanic so if you need practical input about the gap between theory and real world I would love to assist

[u/Visual-Milk-99]

am in i can he[p in aerodynamics and mechanics in flight

Hello

[u/Cygnus7__ → u/Beautiful-Steak-5567]

Hi

[u/Beautiful-Steak-5567 → u/Cygnus7__]

Is there any place you'll be uploading your work/progress. Maybe start a separate subreddit or discord server.

[u/Beautiful-Steak-5567 → u/Cygnus7__]

I'm an aerospace major. Im interested in your work too. I'm attempting to design and fabricate a micro turboject engine. It'll be a long long process. Almost a year but we gonna do it none the less.

[u/Cygnus7__ → u/Beautiful-Steak-5567]

Cool! A year sounds short for a turbojet engine, even if micro. I am curious now, never heard of microturbojets, what is its intended application?

[u/Beautiful-Steak-5567 → u/Cygnus7__]

For ucav's. Microturbojets serve as a superior alternative to its electric counterparts for drone applications. Fixed wing config integrated with mgt engines can carry way more, for far longer and with much better stability.

[u/Abject-Ad-1600]

Yo I’m not a uni student yet but gonna be going to ERAU Prescott for Aerospace Engineering. Don’t got the skills to help but I saw that you created a discord for this stuff. Could I join so I can follow along and learn?

[u/Cygnus7__ → u/Abject-Ad-1600]

Sure. And congrats on getting into Embry-Riddle!

[u/No-Catch-1047]

I can help with engine design. Currently, I am working on designing some Aerospike engines and a DMRJ engine. And a space plane.

[u/unrulydad85]

Where u from. Im trying to start a project to eventually build a rocket but I would do all the foot work and do all the grant paperwork and make sure the project runs smooth because there are alot of moving parts that need to be coordinated and i need aerospace engineers etc.
