Airborne Aircraft Carrier - Testing the FB Limits.

[FoamyDM]

Jason, that was it (mostly)! You’re the best!

That was what i had gleaned myself and have a number of those parts already (project had started) it was nice to see it all laid out thought.

I have a question though, what does the pinnout for the goggles work because i like the diveristy (or quad-versity). I will eventually find it on my own

 

[FoamyDM]

This part of what had me thinking it, but your link looked more... affordable.
The vid had this linked in the description- Link to original DIY thread: https://www.rcgroups.com/forums/showt...

I will have to do a $$$ work up on this. and just see what I can do initially.

 

[FoamyDM]

@JasonK - yes! Perfect.

Landings. I remember the rotor riot quad re-fuel on a Kraken attempts. While some of the issue is the speed delta with two independant flight vectors thrown asunder by the windy moment. Sine if it was landing with corrected orientation. I thought traditional landing assist stuff might be a help here too.

Does anyone know more about the PAPI landing systems. Specifically the Lensing, or the how might I achieve the similar effect with Off the shelf parts, or SLA printing?

I wanted to put these either in or on the rear wingset.
I'm thinking an LED in a Pen tube or slivered Straw set on a printed (incrementally angled) base.

I don't think PAPI is going to be of much use on a moving target. Seat of the pants and luck are going to be required. you could fake it with red and white LEDs. Especially if you had altimeters/GPS altitude on both aircraft and you could compare distance and altitudes.

I've been up front in a few full scale over the years and have tons of sim time flying the glide slope.

The papi was mostly for fun and i think would be a nice touch and. But i really like the idea if using gps positions to shine an appropriate color.
It will be a fin intro into modelling and printing.

so one thing that might be relevant - I was doing some poking at figuring out how slow of a flyer I could come up with - given the space I will have in the near future to work with - and about the lowest flight speed I came up with was 10-15mph... while IIRC a many full sized planes - at least smaller ones - take off/land at 50ish mph. so your forward speed is likely going to be in the 1/4 - 1/3 of that of a full sized craft, but the accuracy of your landing attempt is likely going to need to be 1/10 the grace of the full sized craft. Mix that with the same amount of turbulence just make a full sized craft shake a bit - it can "fling" a tiny RC craft all over the place.

honestly - I think your landing pad is going to need to be designed to be more of a "controlled crash landing" situation.

In the 50's, after an sub exercise, pilot got permission to try the "meatball" on the carrier. Ace Pilot being what he was, aced his two runs where copilot on both runs was all over the place. Close to final, he had one above and one below when we broke. Must have a 200 heartbeat when landing night time and rain plus up/down of carrier. I was sitting in plastic bow in nose of plane.

I agree with you about a plane. Better yet, with flaps and a high flare(E flite Timber) and with lots of practice it might be done. Another is drooping leading edge type flaps, lowers the stall speed(it just rocks and rocks) when in a high AOA. Did you see my video?

If you want a drone to land on an moving object, it is easier if you come in at 45 degrees to moving ship (Split speed vectors are equal) and make it easy on the pilot. A had a mowing tractor and flat bed trailer go about 10mph and my 60 Excell heli moved up so over the flatbed(45 degrees) I was doing 20 and since forward motion vector was 10, now reduced sideward and height motion to stop and dropped altitude with very little movement to adjust forward. Much prep was trying to get the timing of ref spots so we could even get close. Use velco on drone and landing port. Just as bad as doing auto 100 ft in air with heli to land on 1 meter circle for your 10 points when you have wind.

Here is a sample of leading edge stuff. If the carrier is say moving a fixed speed , a good pilot with a proper nose up attitude should be able to take off and come around and land. Carrier could have net raised by 2 servos to stop plane or drone.

Depends on the airflow/turbulence generated around the carrier....

This is a flying carrier which induces additional challenges....

I thank you’re right about that

. Carrier could have net raised by 2 servos to stop plane or drone.

Yup, that and a hook

 

[FoamyDM]

Time to get some more platform testing going. Get a stable flying platform

That should be very minor, besides, your will be above on a glide slope. If right design of plane/drone, should work.

Drone "should" be easier than plane.... FPV anyway. I am up to try both.

I have three potential planes and that includes an EZ setup for landing.
