Re: Too funny.

The reason why the story is only being pushed by FOX news opinionists and their likes is that the story reeks so badly that even the NYP journalists that had to write the story refused to put their names behind it.

This is not a matter of censorship, it is a matter of lack of believability, and a matter of stopping more damage being done to an already weakened democracy.

Future airliners will run on hydrogen, vows Airbus as it teases world-plus-dog with concept designs

Holtsmark Silver badge

Re: Looks good to me

What is often overlooked with Hindenburg and other airship disasters (R101) is that these airships were not filled with pure Hydrogen, but rather with a mix of Hydrogen and various gasses found in the air.

Low internal pressure, low technology membranes (see goldbeater's bladder) and long periods between hydrogen exchange meant that hydrogen could slowly permeate out of the lifting bladders, while atmospheric gases, including oxygen could permeate in.

After a while, a Hydrogen airship of that era would fly with a pre-mixed combustible gas-mix.

Should anyone decide to build a modern airship with Hydrogen lifting gas, then the would need to find a way to scrub all oxygen out of the lifting gas. The first thing that comes to mind is to use something similar to a mining lamp to burn off Oxygen while consentrations are low.

I have little experience with liquid Hydrogen, but we have flown using pressurised Hydrogen.

The pressure vessels are massive, and I would expect them to be found intact on the crash-site. Safety systems like in-tank valves prevent uncontrolled leakage.

As long as the system is not allowed to leak into a large enclosed volume, like a garage or a hangar, the assosiated risks are limited.

The ease of ignition of Hydrogen vs. JP1 is somewhat a moot point. There have been more than enough airliner accidents to demonstrate that a hot jet engine can easily ignite JP1. With Hydrogen, escaped gas moves up, up and aawaaay. JP1 can trickle towards the hot engine minutes after having been released.

The Battle of Britain couldn't have been won without UK's homegrown tech innovations

Re: Jingoistic Juices are flowing

The British, much thanks to the US and Doolittle, could fuel their spitfires with higher octane fuels, yielding higher power rates than available to the Germans.

It is my impression (which might be incorrect) that the German engine technology in a number of ways was more advanced than allied technolog. The superior allied fuel negated this edge.

Still.. I am convinced that the British would have lost the battle of Britain were it not for support from allies, and future allies, occupied or unoccupied.

You have much to be proud of, but you should also be humble about it.

EU aviation wonks give all-electric training aeroplane the green light – but noob pilots only have 50 mins before they have to land it

Re: The silence of the lands

Half of the noise of a conventional GE aircraft can easily come from the prop.

In order to make an electric plane silent, you need to install a prop with a sufficiently low disk loading. This may require moving toe prop away from the nose.

Re: Electric planes?

It must also be noted that the efficiency of a combustion based energy conversion has a maximum efficiency of approximately 35% (diesel ICE), whereas an electric machine operates n the high nineties.

Furthermore, an electric drive-train allows numerous advantages with regards to propulsive integration.

Undesired wake interactions can be avoided. Propeller disk loading can be optimized (yielding higher propeller efficiencies at lower speeds). Boundar layer ingestion and propeller / wingtip vortex interactions can be used to further reduse aerodynamic losses.

Electric drive-trains also lend themselves to high redundancy architectures, which increases safety and allows for what would otherwise be deemed to be "risky" strategies like blown wing designs (NASA), further reducing the required wing area and thus drag.

Finally, maintenance- and operational cost can be significantly reduced with an electric drive-train.

These are all things that are being studied intensely, but which will require a number of key technologies to mature before being widel adapted. And meanwhile, the cumulative effect of a couple of percent's worth of annual improvements in efficiencies for conventional aircraft means that there will be a certain amount of catch-up to do as well.

Re: ...

The big diference is that combat aircraft are expected to fly into areas where small bits of heavy metal often traverse through the airspace at supersonic velocities. Thus the chances of a turbine taking damage and shedding bits are intrinsic to the design. In civil flight, the design objective is for this kind of situation not to occur in the first place. Statistics show that this design objective is by and large valid.

Yet, when I fly, I try to avoid seating witin the ballistic cylinders of the engines, which has the added advantage of reducing noise levels where I sit.

"....who we've beaten twice in a World War already....."

The UK not being forced to surrender was very much due to circumstance (that you happend to have the English channel between you and the German Panzers) and lots of help from other countries and / or the people of these countries who were your allies or became so in order to conquer the Axis powers.

Fighterpilots from all european nations (and even some US volunteers) helped win the battle of britain.

Norway, who were then the world's 4th largest shipping nation, sacrificed it's mercant fleet in order to keep the UK supplied during it's darkest hours, Resistance fighters all over Europe kept the UK updated, often loosing their lives in Gestapo torture chambers for dong so.

Reading Brexiteers pulling put WW2 and animosity to Germany as a reason / backdrop for their phobies is sad, because it is plain out wrong. WW2 was wan through European cooperation, and the EU was born out of this.

The UK is not so unique, it is just another nation that has succumbed to the echo-chambers that modern connectivity has created. I dearly hope that we will all learn to deal with this problem, and that the world can return to some degree of normality after this decade of self-induced extremism.

First A380 flown in anger to be broken up for parts

Holtsmark Silver badge

Re: This underlines one more thing

To my understanding, two things put the brakes on the A380: ETOPS and NEO.

New ETOPS rules (Engine Turns Or Passengers Swim), originating (who would have guessed) from the USA led to a lot of new competition that the A380 had not been designed to deal with. NEO led to savings making these competitors being cost competitive. On top of it, there are not enough airports with the infrastructure required to handle the A380 efficiently.

An A380 NEO might change the picture.

A high growth rate is easier to acheive if you start from a low number than when you starting-point has centuries of growth behind it.

A high growth rate is also hard to consolidate with stringent safety-, environmental- and labor-rules.

With this kind of payload mass and flying at these altitudes, this system is designed to carry communication equipment and little else.

Re: 380b?

What they need is an A380 NEO.

The New Engine Option led to savings in fuel consumption that made the extra outlay for the A380 uneconomical.

Getting ultra high bypass engines (maybe with geared fans) onto the A380 as well as the other aerodynamic refinements that made the NEO such a hit would make the A380 competitive again. The question is: Will it be sufficiently competitive to pay back the investment?

I am convinced that they are crunching numbers in Toulouse and Hamburg.

Time's up: Grace period for Germany's internet hate speech law ends

Holtsmark Silver badge


The way I understand this new law, it is NOT about going after the posters themselves, but rather to hold the "publishers" of said posts accountable for them. The idea appears to be to apply similar rules to the publishers as the rules that currently apply to newspapers (if you earn your living from publishing falsehoods and hate speech, then we will hold you economically accountable for this). I know that this may sound strange to an English public, that knows nothing but newspapers publishing lies and falsehoods with no repercussions, but this is how things are dealt with in the rest of the western world.

Seeing the amount of damage done by "social media" lately, I believe that I can live with this.

Without the echo-chamber of today's internet, I believe self-radicalisation to be much less likely, possibly preventing types like mr. Brevik from being triggered. It is, as always, a fine balance, and Germany is struggling to find it.

That said, I feel that there is a somewhat unsavory tendency in German politics to try to use the law to go after perceived nazism. They spent decades trying to get the NPD, and now they use similar tactics against the AFD. The efforts against the NPD were squashed in courts multiple times due to incompatibility with the constitution (too many informers inside the NPD).

In one way, German politicians are stuck between a rock and a hard place. With Germany's past, theyy face criticism when they are lenient with right wing demagogery, and they face criticism when they try to do something about it.

Dear Naive,

please do not turn the Register into the commenzs section for a BBB article about Brexit.

The amount of anti-German xenophobia displayed in those comments is horrifying.

Mrs. Merkel took steps that she believed to be the right ones at a time when the EU borders were buckling, very much as a consequence of failed anglo-american policies in the middle east (iraq war etc...).

This did not leadt to optimal results, but the alternative might have been much worse.

(I am personally critical to unrestricted immigration, but a number of the stories I hear from these people are truly heartbreaking).

Germany now faces the big and difficult task trying to integrate these people. In this, it should not be forgotten that Germany has had to integrate huge numbers before; Peopleb(many of them Jewish) fleeing from the Soviet Union between the wars (which led to sentiments reflected in the UK today), 12 Million Germans fleeing from the Russians in 1945 to 1950 and 1.4 million "German"-Russians after the fall of the wall. Germany also had to refurbish and re-integrate all of East Germany in the same period. Hearing the british complain about having too many Polish plumbers and Romanian field workers is ridiculous.

While WW2 is very much celebrated in the US and the UK, Germany has all thoughts about empire building very much bombed out of them. To the Germans, the British were seen as a sane partner nation, that could serve as a counterweight to the French. How this is currently misrepresented in the UK is quite sad.

And myself; I am neither German nor British, and I live the productive life of an immigrant.
