16kts?

Well, on that note, as they , I’m out.

Best of luck in the future but there is perhaps a reason why this sort thing hasn’t been at looked before.

I have no desire to prick anyone’s bubble but some of your figures don’t really work.

A sea level top speed of of 50km/h is only 27kts. What sort of wing section would stay unstalled at that speed. If 50km/h is the max speed presumably it takes off at less than that. A stiff breeze would see it exceed VMO ….on the ground!

36km is 118000ft! It will need a major (and heavy) pressurization system to ensure that the crew can exist at all. Any problem with the ECS would kill the crew in seconds if they have no space suits.

A propeller simply isn’t going to work at that height. There is not enough air.

Your original question

Could solar powered passenger planes replace Zeppelin type air ships in the future ?

The answer is not yet…if ever.

The Unknown Soldier by Neil Hanson is well worth a read. The story of three different soldiers whose remains were never found. It also goes into the history of the Cenotaph and the aftermath of the conflict. The bits you don’t often hear about.

So where would you get the air for the pressurization system. Being pressurized adds a lot of weight to the structure , especially one that could cope with 65000ft!

Congratulations on getting those accepted – it isn’t easy!

Anyone thinking that capital punishment is a good idea should look at the case of Stefan Kiszko, or the Guildford 4 or Timothy Evans ……..

Absolutely right j_jza80. I don’t see how there can be any justifiable complaint against remembering or commemorating one of the most important wars in mankind’s history.

It isn’t massively witty though is it… using my own comment back at me. Not the sort of thing one might expect of an “original thinker”.
