IDW 0020: AT-APC Hovercraft [VOTING]
Topic: AT-APC Hovercraft
Background: Present day. Manufacturer Griffon Hovercraft is trying to develop a truly all-terrain vehicle. Current hovercrafts offer the advantage of being amphibious and able to travel over sea or land mines without danger but are limited to relatively flat surfaces. They want you to develop a hovercraft that is also suitable over more mountainous terrain.
1. Design a hovercraft for use by the military as an armoured personnel carrier.
2. It must be able to deal with rougher terrain than current hovercrafts.
MULTIPLE VOTES ENABLED
There are four disturb reactors and two adjustable ones. The intention is that in difficult obstacles the hovercraft would be able to save them with a powerful impulse.
The Military Fast Attack HoverCraft, was designed as a fairly quick strike vehicle. Carrying 5-8 personnel, not including the two necessary drivers. Two drivers are needed when not in auto mode, as the 4 exhaust thrusters, are independant and can be oriented in a wide range allowing diverse body movement for the vehicle. Although landing can be done on the body itself, the ring/grates attached to the thruster body, are there to protect the thrusters should the be landed on. they can support the weight. The failings of the the FAMHC that caused its lackluster sales and use, was in that there are so many moving motors/servos and struts, maintanence of the craft was not realistic.
The main issue with conventional hovercraft on rough terrain is that they operate on a cushion of air trapped within the skirt, if the craft gets titled over rough terrain it allows the air cushion to escape. The solution on the Hippo is to have 6 independent air cushions/skirts, each individually powered and articulated, allowing a constant level of lift over very rough terrain.
The Hippo has 3 crew, one driver front and center, an officer and a weapons specialist, 10 fully equipped troops can fit in the personnel compartment behind the drive cabin.
It is powered by 2 jet turbines with thrust vectoring to provide drive and steering.
Armament consists of twin Metalstorm electronically fired pods, forward firing only used to clear the embarkation area, and a triple barreled Metalstrom 40mm turret for general protection. It also has multiple grenade launchers and smoke generators.
Since hovercraft control like drunken air hocky pucks, i decided that the first thing you would need to do in order to boost the movement on rough terrain would be to add friction. The legs are not meant to lift the entire weight of the craft, but mearly to push off against or pull towards, much like a roller blader moving forward from one fling to the next. this would allow a crab like scuttling motion i would imagine. It also would allow upward torque for pushing the main frame of the craft up inclines and the like (nothing huge mind you). The feet could be bio mechanical, but i was going more for a fabric covered look.
I made this larger than most, it features a split frame design so the forward 'cockpit' is hinged with the rear. i would say around 20 marines could fit into this beast. Driving would either be done remotely, via AI or internal pilot using mini cameras.
Leg 'feet' could be switched for wheels or whatever depending on the mission by using the modular pod attachments.
This hovercraft APC provide excellent mobility, speed. lethality and survivability for the Infantry and a toilet is also provided in the vehicle.
The Land-Griffin ACV-IV is an extensive modification of the Griffin AVC-III, this vehicle is optimised for advanced terrain operation. Although it still retains its amphibious capabilities the Land-Griffin is only suitable inland or close to shore operation rather than the full ocean operation of AVC-III. Replacing its marine characteristics are improved dust exclusion, increased armour, better nap-of-earth flight technology and improved manoeuvrability even with a greater weight.
The vehicle is capable of transporting a squad 40 combat ready marines and their equipment or 14 marine and two light transport vehicles. The Land-Griffin is envisioned to operate in a medium combat lift role with sufficient fire power and armour to support troops as they go about their mission.
Four lifting fan and cushion units are mounted at the corners of the carrying body. Fan units are capable of independent rotation an elevation so that they may optimise coverage on uneven terrain. At the centre of the main body is a trio of large turbo-fans these are used for balancing the craft, providing extra thrust and giving sufficient lift for short 'jump' flights - the exit nozzles of these fans have thrust-vectoring fins for additional directional control.
Main propulsive drive is granted by two co-axial mounted paired turbo-jet engines, these are located on a pivoting base at the rear of the main body with a +/- 120 degree horizontal and +/- 45 degree vertical range of motion.
Armament is sufficient for the vehicle to defend itself and also act in a light to medium role giving fire support for disembarking troops when deploying into hostile LZs.
*Main armament is a pair of quad mounted 25mm chain guns for engaging light-medium vehicles, infantry and helicopters to a range of 1.5 km – both units are mounted on raised towers to give better axis of fire without exposing the vehicle.
*A 12mm gattling cannon is turret mounted bellow the command module for engaging light targets long path of travel.
*Four open gun positions on the vehicles flanks have multipurpose mounts for either heavy machineguns or grenade launchers.
*AA defence come from a dorsal mounted ground to air missile system.
The Griffon 1121 troop transport hovercraft is ideal for multi-terrain warfare. It's four, side-mounted turbines allow for increased lift-stability/steering at sea, while converting to hydrolic, shock absorbing wheels for land based missions. This quick conversion makes the 1121 unlike any other hovercraft, expanding maximum range for troop transport and artillery support. The 1121's surface is designed at angles for increased stealth and it's twin cannons, with a firing range of five miles, makes this craft a formidable foe in both sea and land campaigns. Max crew capacity: 50-60
The Griffon 'Millipede' APC transport is a next generation hovercraft designed to navigate a variety of challenging terrain. Each jointed segment is supported by a lift turbine that can be tilted to allow for forward and lateral movement. This allows for flexible navigation capabilities, as well as eliminating the need external drive blades or jet engines, which would be obvious targets for enemy fire. The millipede has two identical 'head' segments - fore and aft - that allow for immediate change of direction. On each are two defensive/offensive hardpoint weapon pods which have near 180 degree movement. Because the millipede is designed with components in mind, it can be customized to suit each mission. A typical configuration will be composed of fore and aft drive segments, a communications segment (picture here behind the forward drive component), and anywhere from 1-6 troop segments, which can carry up to 12 soldiers each. Each troop segment has two quick-drop assault ramps for rapid deployment of personnel. in development is a medical segment, which will bring state-of-the-art medical facilities to the frontlines.
How it works
The Dream Walker > WIP and it didn't quite fit the topic.
cesaraguilar > I changed your description a bit, is that what you wanted to say?

I'm a bit upset that i didn't pay attention to the topic
But its okay, i understand why im not entered. I didnt even finish. Good luck to everyone else.

Cesaraguilar – I think that I can see the direction you have taken with your design that the craft can use its rotating engines to ‘hop’ over obstacles. My feeling is that this design is too marine based and does not address the problem of rough terrain well enough.
Dragonspit – A sound design concept although it looks rather flimsy. I could believe the method of operation with the independently operated thruster-arms. I like the reference to its complexity limiting usefulness.
Goran – The most advanced design, the brief is well represented with both the ortho-views and the in-situ visual. Very aggressive and dangerous in appearance .
Sogbad – A very solid and believable design, I could easily see this craft in service. Not a very elegant craft but it properly looks the business.
Legato – I liked the supporting legs idea, the rest of the design is very clean and believable.
Delta-Charlie – although a fairly practical design for a normal hovercraft I did not feel that any of the difficulties facing a rough terrain vehicle have been addressed.
D-Holme – I apologise for not being able to produce a better entry this week.
Collinsully – A design with some interesting ideas but I am unsure of the practicality of the turbine come wheel devices.
sillikONe – Very nice and different approach to the problem of this brief.

it was a tie for me between goran and sogbad's design. they are both well conceived, and both rendered flawlessly. i ended up voting for goran.
while goran's design took some liberties with traditional hovercraft air cushion technology - it is still a craft that hovers, sort of like a harrier jet would. and his detailed schematic explain the functions of his machine very well. in the end, it was just the sexy design that got my vote. a very cool looking juggernaut. on an illustrative point - needs a little breathing room on the right hand side of the image. i see you added that extra gun mount. it helps a lot.
in terms of sheer believability of concept, i think sogbad wins this round. i could see this thing rolling onto the battlefield today. nice plausible design, with great attention to detail, although somewhat utilitarian.
i like legato's design as well. very unique. human tech meets insectoid/arachnid. that thing would look crazy rolling across the field at about 50mph or so...those spidery legs going wild. freaky! i'm guessing they would work like the legs of a water strider over water surfaces? nicely rendered.
collinsully - this seems like it would be most at home in the water, being an agile battleship or destroyer type landing craft. it's hard to picture it traversing anything other than very even terrain though. it's wheel/legs seem a little weak for the its bulk. i guess it would be ideal as a beach landing craft. i like the stealth design. nice rendering too.
delta charlie - seems like a conventional hovercraft for the most part. i think it needs some innovation to improve it's land capabilities over current tech. although, the importance of a proper commode should not go unnoticed. you get props for adding something that's commonly overlooked in the military transport arena. i like the design. very aggressive.
d-holme - pretty kick ass piece of machinery. i imagine it to be pretty sluggish, but it hefts a lot of firepower and protection as a tradeoff. would have loved to see an angled view of this. this would be a great vehicle for a group of players to command in UnrealTournament 2004 or 2007.
Cesaraguilar - looks formidable, but mostly seafaring. would like to see more on how it performs over land.
dragonspit - pretty cool, light and sleek. maybe a little delicate looking. i actually really like the V.1 craft that you have pictured in the upper left - the hover-toad
nice entries everyone

My Vote and Comment.
First time posting in "ConceptArt" and it is a pleasure to meet you all. Moving on...my vote went to SilliKONe for his amazing idea of the topic (in my opinion of course), a well drawn picture and good discription. Everyone else did a fantastic job on this topic as well. I was close to participating too, but I was discouraged since I also had a six seperate pad idea just like Sogbad's adn I don't have an art program (Photoshop, etc.) lol.

I agreed with Blue Severin.
My personal view of this forum in general, is that although we should follow through as well as we can on the actual design concept, this whole site is basically about art and concept art. so I tend to vote more towards what Goran did, because of the exection and that it is eye candy, with a purpose. If it were completely out of line, then maybe not. But Silkone's design concept was the mosty coolio and practical so I didnt want to leave that one out.
Other mentions were Sogbads for sure. Nice overall desing and execution.
D-Holm, man do you make ANYTHING that isnt gigantic, lol. what a mountain of machine.
Legato-I liked the idea, how bizarre that would look. I would like to have seen that animated.
the others I just didnt see as how they would manipulate other than the flat surfaceds of today. not that they couldnt, I just didnt see it plainly.
Lots of good ones.
I only live for today, but I'm one day behind.

Dragonspit - ha, a bad habit of mine but I have always been a believer of over engineering. I could see big all terrain transport hovercraft quickly hauling troops and materials around the battlefield in fast advances and flanking actions.
If I get this weeks IDW finished I think it's going to be even more of a beast.
silliKone - thanks, I'd have liked to take it further and do the idea some justice. I figured that you don't want to be going too fast in close terrain and you'd need to be able to pack a decent bit of fire power to deal with infantry getting up close. I took some inspired from Huey's and Hind gunships albeit on a much larger scale.

I give Goran a big applause for his render, fantastic stuff !!
But sillikone gets my vote for the originality of the design. Great imagination!!
November 8th, 2006 #12
Since goran and silliKONe both got 50% of the votes (multiple votes do weird things) and it's been such a tight competition, I'm declaring it a draw.
Also because goran doesn't compress his images - 700k! Are you kidding me?! Try using the 'Save for Web' option in PS.
