I didn't call them ugly or beautiful. They fly. They are just uncommon in a world where the most common plan view is the Cross of St Thomas.

Don't forget circular wings Question - Circular wing

Is this the Who that Horton heard?

Yep.

Dilbert, the US navy pilot

It seems that the original meaning of 'dilbert' has been lost. All references I found to the meaning of the word refer to the comic strip detailing the life of an office worker. That strip started in 1989. Seems that Dilbert was forgotten after the Korean Police Action.

He had two other WWll contemporaries, SNAFU, and Kilroy, although Kilroy was not involved in training material.

You are lucky they didn't torch it as well.

Now we want to know what you bought. Pictures, please

I will give you my experience, as it was a good one, and I am very pleased with the outcome.Cheers J

It all goes back to "A fool and his money are soon parted." Unfortunately, most fools not only part with money at the sale, but continue to do so trying to resurrect a lost cause.

The problem is that over the new year period ( I think it was) in the space of about a week 5 or 6 people died when despite warnings they drove through flood waters and were washed away.

#481 looks like an Airtruk on steroids.

Don't even think about it ! Lucerne mown low and often won't last. It is designed to be in a rotation so it can recuperate and needs to be let grow out (30cm high) quite often or it will die out.

It's just that I was up near Dubbo last weekend, and there isn't much of any type of grass on the ground due to the drought conditions. I thought that a perennial plant would be better than an annual grass.

Unless you have landed on your feet, you have just jumped into a money pit.

NEVER, NEVER, NEVER buy an airplane sight unseen and without a pre-purchase inspection by a qualified, independent maintenance engineer, who has been provided with all the information about maintenenace issues that have been found with similar models of plane.

In the words of my dear, departed pater, "Son, Don't go pissing until your water comes."

Would a perennial such as lucerne do the trick? Once it has established a deep root system I think it might withstand being mown short.

These bloody Fly in - Fly out LAMEs will be the end of fixed base operators!!!

My wife was a radio operator working police radio dispatch in Sydney. She came home one morning and told me of an open-mike incident that had happened on night shift. It was at a time when women were beginning to be deployed on General Duties. For the first few months of all constables' (male & female) worked with a buddy, learning the ropes. Naturally this lead to romantic relationships forming between naive female probationers and worldly-wise Senior Constables.

For this buddy/probationer pair, quiet night; a secluded parking spot, and an open mike entertained the rest of the police on the same channel for some time.

Her favorite trick when I was working the car and she was on the radio was to frequently call my car to report its location. Then towards morning she would call my car and tell me not to forget to pick up some milk on the way home.

O M E What no cigar for me!.spacesailor

Besides, with the demise of high performance piston engines in aircraft due to the uptake of turbine engines, the need for fuels with Octane Numbers above 100 exists in only a very few, sports vehicle engines, so the production of that sort of fuel is bespoke.

Because fuel contains a certain amount of energy, and you can't get more energy than that what's in it. ICEs are quite inefficient, but changing how you deliver the fuel is not going to make that big a difference. Basically a certain amount of fuel will make a certain amount of power. End of story.

Thanks 1@kasper[/uSER] That is the sort of answer that I was looking for.

REASON 1: Fuel/Air mixture becomes chemically incorrect as throttle butterfly opens on the 'request for more engine revs'.

REBUTTAL: If you watch the video, the bloke adjusts the fuel/air mixture with a valve BEFORE the mixture reaches the carburetor, and the engine revs are controlled by the throttle butterfly. This seems to replicate the mixture/throttle combination already used in aircraft.

Keep thinking.

Consumption will be reduced because you will crash at the end of the runway as the engine fails ;-P

We don't need to, the fact that such designs aren't currently operational in today's advanced computer world says it all!.,

Hey! I know that this idea can't produce a much reduced fuel consumption figure, but you blokes have missed the point of the challenge.

Putting aside the idea of "nasty oil companies smothering ideas that would reduce consumption, try coming up with the real reasons why this process is impractical.

I challenge you to apply your knowledge of aircraft fuel systems and fuel management to say why you can't reduce fuel consumption this way.

Came across an interesting topic for conversation while surfing the 'Net - Can you run an petrol engine on fuel vapour and use miserly amounts of fuel to go great distances?

The basic concept here is that using the vacuum created in the intake stroke of an engine, air is bubbled through a tank of the usual fuel the engine runs on. The fuel/air vapour then enters the engine through the throat of the original carburetor, with the throttle butterfly controlling the volume of the mixture entering the engine, thereby controlling the revs.

This video shows that an engine will run using this set up, but it raises many questions about its practicality.

The first thing to consider about the experimental conditions here is that the engine was set running at constant revs. That does not happen in any sort of practical powerplant use. Revs range from idle to maximum safe, depending on the requirement at the time.

Also, to get the engine started, the air/fuel mixture had to be adjustable.

These are two things that got me thinking about the experiment, and I haven't mentioned fuel economy.

I invite you to watch the video and apply your knowledge of fuel management to form an opinion whether this process is practical for normally aspirated 4-Stroke engines powering either aircraft or ground vehicles.

So it's not air flowing over the wings that creates Lift, it's fuel flowing into the engine that does the trick.

Here's a picture of a load of sailplane fuel being delivered to an airfield

The insects seem to take it in turns to bite people at Dunwich Airfield.Over the summer, the March flies have been in residence. I expect after this rain stops, the mosquitoes will move in and when the westerlies start later in the year and combine with a high tide, we will get visits from the sandflies!

Interesting video
