new airport idea

Hi,

Airports are expensive, reinforced runways etc..

Here is an idea: instead of runways, use 10foot deep water (or antifreeze in winter) and build planes without landing gear and tires/brakes.

This will prevent fires on crashes, so no firetrucks needed too.

Also saves on cost/weight/maintenance of landing gear/tires, which are prone to failure sometimes.

The saved weight could go to extra ranged and or reinforcement required for water landing.

Also now flying over the ocean is less dangerous, so some flights may route more direct.

Also for unplanned landings, there may be more suitable water bodies than runways for aircraft.

cheers, Jamie

Also these airplanes would all be easily converted into water bombers (seems they will be valuable from more forest fires), and could even use the runway water if necessary.

One other benefit, above wing engines can have larger diameter, more efficient fans than the obsolete designs under the wing.

Obviously you are not aware of the huge excess drag created by seaplanes. I would also point out that they can't land in the open ocean because condi tions are not always suitable. A plane can't land in at all rough seas. T hey land near shores of lakes and such more than large, open water with lar ge waves.

Hey... I know! We should place a 4 foot deep pool 30 yards wide right down the edge of the runways.

Better than sand.

what is the purpose? I think it is easiest to just flood the whole airport and have underwater LED runway lights.

To solve the excess drag, if it is a problem, differential flow water runways with pumped water flow in opposite directions for the time required for takeoff and optionally soft landing. 100MPH water flowrate should be doable, and the flow energy can be somewhat regenerated by the same pumps.

And how are we supposed to land in Cleveland in the Winter?

That's the best part--no one would ever suffer that horrible fate again!

The city of Kalamazoo has heated sidewalks and after a snow, they are all clean and dry.

Heated runway pools.

How big of a 'boat' do you need to float a 747? GH

Remove the 'boat' from the bottom and attach ice skates or skis.

Hi,

I suggested antifreeze, which could also deice the airplanes, but maybe a better solution such as recessed runways to have geothermal heating effects, with low sloped ramps at the ends as well as possibly impact resistant small rubber/plastic hollow balls that float on the water for a thermal insulation layer.

Hi,

A 747 will float itself after putting the engines on top, and putting a couple layers of honeycomb composite up to the waterline.

The Cleveland Orchestra is famous for their Christmas concerts. That's a good enough reason to fill it with Prestone. Then the amphibious 747s can land with their great big pontoons.

But why save money on runway maintenance and not on roads? We shoudl also flood the roads and make a giant Venice.

If you want to land a 747 on a boat, SpaceX is already doing something similar for landing the upper stage fairing on a boat, seems like a similar problem except higher speeds involved.

Also if there are high speed boats on the airport runways they could both catch and launch the airplanes, cable driven high speed boats likely, relying on software to automatically land the airplanes.

cheers, Jamie

The floating hollow plastic balls are a bad idea as they would not work with either flowing water or high speed take off. So antifreeze/saltwater and geothermal heating, as long as the antifreeze wasn't too viscous for taking off.

Three problems with that:

  1. Atlantis may have a copyright

  1. Only Tesla cars will work (at least according to Elon Musk)

  2. The benefit from decreased maintenance is outweighed by the decreased transportation efficiency I think. For an airport the transportation efficiency of the runway can be low as it is a small fraction of the overall travel distance, but for a interstate highway you will need a way to get past the higher fluid resistance, maybe hydrofoil vehicles? Also the winter freezing..

cheers, Jamie

Why not in-wing engines as in DH Comet ?

Practically all flying boats have been high wing constructions. One severe problem with flying boats is protecting the engines from corrosive seawater. Using high wing in wing propeller engines helps a lot.

The only jet engine powered flying boat that I have heard about is the Be-200 with jet engines above the wing and quite far back, so the engines are quite well protected against seawater.
