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

Another thread turns into a insult-trading exchange with a bit of playground bullying thrown in. Those who dare to put their points of view forward that may differ from others should be free to do so without the pathetic name calling and insults that seem to be rife around here nowadays.

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!

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.

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.

So you had to trawl through the net back ten years to find that. Don’t forget if you go back a couple more generations you will find a Bomber Command Pilot who called his dog N*gger! I suppose you would call him a bloody fascist as well!

Yes, I noticed his views seem to be similar to a few on here….funny that….

Interesting that according to Wiki it used 560kW engine rather more than your design.

128m span!. There isn’t an airfield on the planet that wil be able to accomodate it! Maybe you should think of a seaplane.
