Building a HIGH POWER Rocket Plane

[@Project-Air]

For anyone who doesn’t already know, Emma is the first full-time hire at Project Air 🙌 She’s an incredibly capable engineer and actually much more qualified than myself, who basically self-learned everything. Over the years I’ve had many friends appearing in my videos, including Sam, Mike and Hannah, who were always keen to lend a hand with building and filming when they were available. 🎥 What a really needed, though, was someone to help design, build and test things full-time. Emma originally worked in the same engineering company as Sam, who recommended her. I saw she was the ideal sort of engineer to come and help out with Project Air operations day-to-day. I’m really excited about all of the more complicated projects we’ll now be able to take on with her versatile skill set in electronics, CAD and other areas, and I’m also very pleased to highlight a woman in STEM through this channel, something that is still lacking on KZbin (and in general). I’d like Emma to be treated with respect as it’s hard enough to appear on camera without inappropriate comments about her appearance or relationship to myself. She is a valued member of the team and I’m very much looking forward to all the future projects she is going to be helping with. Looking forward to the next project! James

[@legoflightturtleperson243]

absolutely love your videos, I have been watching your channel for a long time and your creations never disappoint. here is an idea of something you should make. one of those car plane boats you sometimes see in movies or games were you can design your own planes. maybe a buggy with floats and wings on the side or just an evolved sea plane with bigger wheels. Make sure to strap rockets to the back! I have never seen someone make it so it would make for great content. thanks for making great inspirational videos.

As a 60yr old I really appreciated seeing you take Jetex & balsa structures to the limit. I had many, and if fact although you mentioned the 50s my last was in 1985, although Jetex parts were a little hard to find by then. It was a tissue & dope plane that immediately burst into flames. Dope was still off-gassing! I dropped it immediately and it sat on the ground leaving, within 30s, a black skeleton of failure. Gutted.

Great job to both James and Emma. Nice that you mentioned Jetex. I'm 70 and it brings back good memories.

[@firstmkb]

Emma is amazing, and I’ll leave it at that! Great design, build, and testing. My only suggestion is to get a motor with a longer burn time. Aereotech makes a 38mm diameter single-use motor with 320 N-s of total thrust and a 6 second burn time. It doesn’t sound that long, but their similar sizes burn from 0.6s to 2.3s. I used one on a LOC Precision model for my Level 1 certification and it was a crowd-pleaser!

[@craigegdell7913]

Loved the stealth Dalek flex 🙂

[@AlexOnABoat]

That was fun, but here's the challenge for you before you tuck this plane away for a happy retirement. Multiple rocket motors triggered one after the other. I feel we need more height.

[@raysun2be]

I was thinking along the same lines, a couple of the less powerful engines, then a couple of the powerful ones triggered one after the other. It would be great to see how high it could get for longer glide time!

[@thefantasyforge5015]

Nice to see you revisit retro planes with modern tech. I'd love to seem more of these. Emma is also absolutely right about it looking like a kid's drawing, but it glides nicely.

[@cedhome7945]

Tip - as the rocket will get lighter as it burns putting it as close to the centre of gravity as possible will help.so above or below the wing would be better. Great fun all the same 👍

[@SilvaDreams]

The engines themselves aren't very big or heavy, he just kind of stuck a model rocket on the nose.

im curious why didnt you use fishing line to stabilize the first plane ,you could brace the tail against the pegs that hold the main wing and brace the wing against the end of the tail ,i think it would've been strong enagh to handle not crumbling under its own weight fishing line is extremely strong and you can use it to eliminate any unwanted twisting forces by tying things to fixed hard-points on the plane

[@JustSomeVideos0]

That's precisely what I was going to write! Great plane but sad seeing those wings and tail flexing when some line would have resolved most of the issues!!!

Super impressive engineering skills and glad you finally went with the box frame. I have seen some larger motors that have about 20 seconds of lower thrust, which may be more suitable for a longer flight (Apogee Components, Aero Tech G18+, 19.8seconds). You have a nice looking Dalek in your workshop!

[@zecretw7272]

That was my thought aswell, lower force and longer time. Please revisit with that type of engine. ❤

[@TricksterJ97]

Yes, it gets going fast enough for the wing tips to start fluttering. Less thrust for longer would be better. Maybe two smaller rockets?

[@bravelyHomoSapien]

@@TricksterJ97 In for a penny, in for a pound… Let’s go for 10 smaller rockets along the wing 😊

[@kennethcameron7401]

Pish with the G18, let's go with an Aerotech H13ST-P! Burn time of 15 seconds, but a much higher total thrust of 211 newtons and a max thrust of 43!

[@Lord.Kiltridge]

Well done. Seriously interesting. Horizontal acceleration can be mitigated by converting the excess energy into altitude. If the airframe is not strong enough to manage the thrust in the horizontal, pitch up and climb. You can go higher instead of faster.

[@musiqtee]

Yes, I had the same idea - although from a _very_ theoretical experience with procedural energy management in flight sim airliners… 😅

[@Skinflaps_Meatslapper]

That's the standard procedure for when you have more thrust than your airframe can handle in level flight, you point it up and gain altitude instead of speed. It's a ultra high lift glider, not a high speed hotliner, the point of the rocket should've been to get as much altitude as possible for longer glide time...not see how fast you can make it go in level flight. If you're hitting flutter speeds, you're too fast and wasting the thrust on hand with drag.

I actually built and flew a Jetex Saunders-Roe SR.A/1 (a model of the S/R flying boat, with auto-rudder), in the late 50s ! It was my first model aircraft, and it worked so well, it just flew and flew - right out of sight ! I was devastated, and thereafter stuck to control-line flying, until r/c models became a thing

[@Fotoschiki]

The fate of the 3D-printed tail part reminds me of something an expert from a plastic manufacturer told my dad on an industrial fair a few years ago: "If you know enough about plastics, you use metals". Someone should have told Stockton Rush ...

[@douglascaskey7302]

And in some cases if you know enough about metals you use lightweight, high temp reinforced carbon composites (RCC). Metals such as titanium and Iconel are not easy to work with compared to carbon composites. Think SR-71 vs the SST. In the case of the Titan... it wasn't neccessarily the material choice per se - it was the design for the material in that case. If it was a spherical shape... it might have been a different story. It's why God didn't make eggs tube shaped. 😏 That being said... it's not well understood yet how composites fair under repeated flexing in deepwater applications, when compared to metals such as steel, titanium, or aluminum. As proved by the Russian's titanium is not a good choice as it's too expensive and hard to work with for subs. Aluminum.... ah, I don't know - you going to have the same issues with flexing and fatigue, along with corrosion from exposure to sea water. IMO steel is probably the better choice - at this time.

In addition to that it covered power systems which included Jetex! I've tried looking them up in action, but there hasn't really been anything that was worth reading about or watching on youtube. Thank you guys!

I know absolutely nothing about airplanes and flying but I hydrofoil surf every day. It’s so awesome to hear you talk about wing designs.

Loved the video. Back in the late 1960s a friend and I designed and built a wide wingspan glider - it was probably only 6 feet but considerably bigger than other sailplanes we built, sadly no pictures. Balsa wood with dope covering and duralumin joints between the two halves the main wing to allow for transportation. Free flight launched using a tow line. It didn't survive many flights before structural failure. Happy days. We're now in our mid 70s.

[@christopherleveck6835]

Im only half way through..... Carbon fiber square tube on tail would work..... Need larger servos. It may turn ok but it would do better with a little dihedral in the center section. Not sure where you got your airfoil.... The idea of using an under cambered wing is solid. But usually the camber is behind the wing spar which should be close to the center of gravity.

[@SpacemanFPV1]

i agree larger servos, as well as a wing thats not the same width all the way througgh

[@kadmow]

Even triangular foam board -simple, cheap and rigid geometry - beats cute and expensive (where there is no optimisation nor competition at the bleeding edge)..

[@ericseidel4940]

An horizontal stabiliser is NOT a lifting device, but rather pushing the tail DOWN to counteract the tilting moment of the main wing. So should have, if any profile, a symetrical one.

The glider circled around as us kids kept track of it running all around the park where it was launched, we wanted to be their when it touched down. That is just about all I remember of the glider.

All went well initially, but those of you who remember such days will recall that over months the balsa became impregnated with fuel, so on the day that inevitable occurred, and the thread snapped, the aircraft created a magnificent blaze in the sky.

I built a 1.6m wingspan glider with diy rocket motor approx 10 yrs ago. This is fun! good memories. I bungee launched the glider, then activated the rocket with a short circuited carbon based resistor(they will glow red).

FANTASTIC! i wonder what motors you used (as someone who builds and flies rockets) i assume Cesaroni Pro38 G and I motors?

Wow, that right wing tip almost departed during rocket burn ha ha. Well done James and Emma, looking forward to seeing more positive energy from you in the future.
