Title: small dropship
Post by: Noordung on July 10, 2014, 05:53:32 pm
this is work in progress small dropship. 2x1 rma. changing wing position when landing so it take less place in map. cargo hold is 6x2 tiles.

Looks promising. A question though: what stabilizes the aircraft while in the air? It looks like a single rotor helicopter which would go into crazy rotation around itself....

no those are wings not rotor :D
tail is missing, landing gear and some aditional thrusters for vtol.

i agree that those wings are not the best and look like a rotor... i will change them somehow.

(name) small dropship. pegasus X engine. retractable wings and aditional oxygen tanks for closed cycle engine while landing/takeoff so it can land in streets or similar closed narrow areas.

Dude, how many soldiers will transport this aircraft?
Title: Re: small dropship
Post by: Noordung on July 19, 2014, 10:04:55 pm
12 i guess ;D
probably 0 becouse dont think it will ever serve as a transport. there may be some chance we could see it as military transport in same maps if someome will do it. becouse didnt see much new stuff lately... (maps, models...)

there is 6x2 titles of space inside. doors are 2 wide. so probably 8 soliders.

I still want to replace the Raptor armed dropship in our maps. And if someone provides a model that fits our needs, this is not a huge deal. So there is no reason to be that pessimistic.  ;) The biggest problem with our models is texturing most of the time. But if the model itself is good enough, we may decide to just put it in and hope for somebody to step up and do a good texture for it some day.

OC, the Raptor uses alien technologie, and the model is expected to show this. Also, it needs to carry ten soldiers.

For your model, I think it already looks very good. Showing the weapons this detailed is not good imo, because the equipment may change. So I think a more subitle weapon bay may be in order. Did you check how much tris the other dropship models have? Imo yours could take some more details here and there.

My only concern from your pics right now is that it looks much like a Firebird II.

i think Mattn already put new raptor model to datasource http://ufoai.org/forum/index.php/topic,8582.45.html
if you dont like it i can change it just tell me what to change it.

about this small dropship. those are lasers and not detailed weapons, just showing where wapons could be placed. puting weapons in weapon bay is good idea. just have to think a little where to put it. where can i see this firebird II? never saw it before.

when you say need space for 10 soliders... if UGVs will eventualy be used than more space will be needed in cargo holds. so anyone who decides to make new model should think about that.


i also think we could have more aircraft types. now we have saracen and stiletto that are more or less museum exponats. (since there was no armed confilct for about 50 years and no need for new weapons) maybe as soon as we start playing we could be informed that our scientists found out about some advanced unfinished military projects for advanced aircrafts. we could finish those prijects upgraded with 2084 technology (mostly civilian) but changed to be used in military. i like how firebird stated its got pulse jet. maybe also changing some descriptions so we could add more of this for now mostly theoretical technologies. maybe even put those ideas to new topic.
just for start here is one http://en.wikipedia.org/wiki/Ayaks http://en.wikipedia.org/wiki/MPD_thruster

much changed light dropship.
just added materials in blender so you could see how it suppose to look like.

replaced some pictures with better ones

It could be good to put an hump over the craft where the fuel will be stored.
Title: Re: small dropship
Post by: Noordung on July 23, 2014, 07:54:23 am
we can say its got fuel tanks in wings. yes i know also wings may be a little to small, but if we want small dropsip 2x1 rma a little realism must be put aside.

besides we can say this small dropsip is powered by small fusion reactor and propelled by some sort of electrical engine. could be MPD thrusters. so aircraft would have virtualy unlimited range. 8) year is 2084 after all.

Well... i solve the problem doing "refueling" on all my bases, i jump base to base to reach all the planet. So, it could be possible to do a small dropship without reach fusion reactors. Fusion reactors can give very high amounts of energy, but transforming electricity to movement is not easy, not for aircraft, because the movement relay on air displacement. There are only two possible solutions; turboprop or electrical propellrs (limited to subsonic speed) or gas acceleration (gas turbines, for example). Another way is the ionic engines, but it could be extremely unfriendly for environment.
Title: Re: small dropship
Post by: Noordung on July 24, 2014, 08:50:23 am
why do you think ion engines are extremly unfiednly for enviroment? you can use oxygen from air as propellant and you than only need very powerful enegy source.
"simper" way it would be nuclear pulse jet. where instead of jet fuel you use nuclear fuel. this would be very similar to alien engines as game describes them but human made. and less powerful.

anyway here are 2 more versions of small dropships.

Post by: Noordung on July 24, 2014, 10:01:56 am
It could be good to put an hump over the craft where the fuel will be stored.
so here are some sort of external fuel tanks under wings. they are bigger now.
Title: Re: small dropship
Post by: cevaralien on July 24, 2014, 07:19:32 pm
Looks fine.

If it not problem, i will give you an idea.

Put the engines at the wings, attached to the fuselage. Remove the upper air intake and transform it in a hump. Why? This is an Osprey type approach. All the fuel can be in that hump and you will have a more realistic aircraft.

Some like this, the Dornier  VSTOL

(http://www.pasionporvolar.com/wp-content/uploads/05-blog/aviones-vtol/plane-dornier-do-31-allemagne.jpg)

but, instead to use the vertical take off engines at the tip of the wing, you can use it in the root of the wing.

It´s only an idea.
Title: Re: small dropship
Post by: Noordung on July 24, 2014, 09:16:41 pm
im sorry but that design is very old and inefficient.
1. closer to hull are engines weaker can be wings thus lighter... lighter aircraft less fuel... you know what i mean.
2. its wasteful to have more engine than you need - all engines should work all the time.

i think the best aproach (most efficient) is vectored thrust. 3 (triangle) points for stable aircraft on landing/takeoff. more points more stable but not too many engines if you dont really need them. i hope you see nozzle i made as i vectored thrust. that was my intention.

as efficient design you can see harrier. just one engine. when landing it got thrusters in 4 points and its stable. from start i wanted this to be 1 engine design. than it look a little strange. but my idea was helicopter like design with one engine at top. just faster with longer reach...

there are many other interesting experimental vtol aircrafts that i would like use as idea.

Harrier was not the most efficient VSTOL. The German VJ101 was better in many ways, but british design wins because the needs of the OTAN changed. But this is a little off topic.

The idea is use two wing engines that use vectorial thrust plus two engines in front. If you want put a single engine, ok, it´s your desing and it´s possible, but the craft is too little to fit a realistic fuel tank. But if you want this solution, i suggest to change the exit of the engines and put it like the Harrier but in the "roof" of the aircraft, in one line. Is something like the Harrier engine with the rest of the craft hanging on. The nozzles can be at both sides-up.

(http://ufoai.org/forum/index.php?action=dlattach;topic=8694.0;attach=9797;image)

I suggest this: remove the frontal nozzles (red) and put it at the side of the intake. The rear nozzle can be the same as the frontal. It´s like the harrier engine design. By that way, the fuel can be stored behind the craft and in the wings.

why do you think ion engines are extremly unfiednly for enviroment? you can use oxygen from air as propellant and you than only need very powerful enegy source.

Toxicity, of course, depends on propellant used. Considering the propellants available on Earth, most effective among technically simple to use will be mercury, which is highly toxic. Especially mercury oxides created when exhaust will be mixed with air, they are much more toxic than mercury itself.
Of course, you can live with xenon, as modern ion engines do, but at cost of bigger fuel tanks, cryogenic system onboard and specially designed ionizer for the gas.

Oxygen is generaly a bad idea -- its atomic mass is way too small. You want a propellant with high atomic mass to have an effective ion jet propulsion. The heavier ejected ion is, the more specific impulse is (impulse gained by ejecting the same mass of propellant) for the same engine design.
Title: Re: small dropship
Post by: Noordung on July 25, 2014, 02:16:34 pm
@sandro oxygen is good becouse it is in atmosphere. so you dont need to have it on aircraft. you also have to consider how easy it is to ionize it. mass of particle its not the only thing. nitrogen might be even better since it 78% of atmosphere.

@cevaralien my first design it was very much like harrier (if you check older pictures) but with engine at top of aircraft it looks a little weird. maybe nozzle could be inside wing (some expertimental VTOLs had it in wing. cut for now this is finished. also changing like you suggested its a lot of work. it would be better tu jsut make another one.
you always have to take in consideration where is exit for soliders, aircraft should be as small as possible (smaller aircraft - more map), it should look nice, and well it should look advanced. so it may not look like aircrafts of our age.
i will cartainly make more different aircrats they somehow become my hobby.

md2 files and uv maps of small dropsip. if it well be ever used in game. + bad textures showing may idea of how could it be painted.

You should make it run off of fusion power and extreme speed vacuum engines. They work like a turbine. But this time they make high pressure inside a chamber even heating the air a little bit and sending out on the other end of the engines. They can use high effecienty linear electric motors wich can be made as loops. Those things simply can rock! They need miniscule place, miinimal repairs virtually every single row in the turbine can have it's own engine(high resilience against ordinary damage). This technology is something on what they also as a high effeciency electric enginge for planes. Only problem it is indeed effective in the atmosphere but neither it is cheap neither powering it is easy. This is more like a jet engine based on electronics. Only effective on higher energy levels. Fusion reactors also could be used in the games. In this year we did the first fusion reactor work. So in 70 years we could easily make them accesible to military crafts. Building more advenced craft is always a have to. So they would never stop producing weaponry. 50 years of peace is nothing, compared to more than 4 thousand years of war. Every country should be still researching into military tech. Maybe not fielding it fast cause it's not so cheap. But they should keep a ready stock in need.
Title: Re: small dropship
Post by: Noordung on August 19, 2014, 12:44:57 pm
good idea. i think we could make new desctriptions for existing aircraft so their technology would be more like 2080s...
Title: Re: small dropship
Post by: Seerorin on August 19, 2014, 01:14:48 pm
Forgot to tell. Only problem with this turbine based system it's can't be used on really high altitudes. Just like helicopters. They have to be under about 6000 metres. Cause if you move higher engine effeciency goes down exponentially. But they are working and will go into civilian crafts someday if they don't invent any better. That means planes will go lower but cheaper(if electricity will be easily stored.). Also any landing craft with weaponry should have rotary turrets and two pilot cockpit. If you go with high pressure turbines you should simply rise model height a little bit. Say there is a fusion reactor in the back of the fuselage. Put a large intake on the top. Heighten the cockpit a bit for two pilots. Also with this you can forget large wings. It should travel need supersonic with these engines small retractable wings should be easily enough for them. They can easily hover. Only problem would be they don't carry UGVs but the plane itsilf could be function as one after soldiers leave it maybe? Otherwise you have to make it a lot bigger. Even tough I don't see any real reason behind an UGV probably will be no use... A wheeled machinegun, meh... But the dropship fliing over the place firing 20mm shiiva rounds would make the aliens think twice about getting into open ground. :D
Title: Re: small dropship
Post by: Noordung on August 19, 2014, 02:41:32 pm
well we cant make all dropships faster than alien ships ;D
and flying so low... its hard to go supersonic on lower altitudes.

baisicly having this vacuum engine with some super batteries would be good idea. onboard AI could work with weapons and asisting pilot. so one pilot is enough. about UGVs... not sure if light dropship is intended to cary ony of those anyway. but heavier (raptor/herakles) should carry some of them.

and we could say weapons (one light) is in internal bay. this way we can have different light weapons and we dont need to show them.
Title: Re: small dropship
Post by: Seerorin on August 20, 2014, 02:01:04 pm
Yeah. I don't think an UGV is some light thing either. It should be freakingly heavy, considering how much armor it carries. Also weapon display or not is up to you. :) Anyways nice work!
