Air-Electric Drive System

Hi,

Try ,how do you plan on getting your motive force (compressed air)in the first place?

How large are your Air Receivers going to be and at what pressure will these be maintained or charged up to by your compressors?

Lets face it the calorific value of 2-3 lts/24hr of "any kind of fuel" is not going to be enough to expand much compressed air if it is required to deliver 50 kW of power through Air Motors.

Nothing is for free in this world. You will have to expend energy in the form of some type of fuel driving reciprocating or rotating machinery to compress the Air in the first place if you are going to do it onboard to enable the boat to cruise further than the length of it's air hose or shore power cable from the dock.

Air-Motor Power

Makes me think of those air starter motors for some truck diesel engines and/or air motor tools....not very quite, nor efficient, nor long lasting without lots of maintenance

Hi,

I apologise if my questions don't seem to be polite to you.

Brian you are right in your recollection of diesel engine starters and air tools these rotary vane type motors are noisy and sadly have a short service life( approx 1500 hrs) even shorter if not properly lubricated when in service(approx 500 hrs).

I am always keen to expand my knowledge and embrace new technologies, I will be waiting with baited breath for the expanded explanation of the system that TRY has given us a teaser of.

Hopefully TRY will be able to kick this off by answering my opening questions in my first post on this subject.

Carl, Maybe you would like to move this and other posts related to TRY's new propulsion package to their own thread to avoid confusion as it seems to have deviated somewhat from the original thread theme.

Guys,

This discussion has been moved under it's own heading, seperate from the Diesel Electric Propulsion thread... in order to maintain subject continuity. Interesting thread. Look forward to learning more.

I'm off to a big flotilla of boats for sale. Good week to all!

Carl

Hi,

Thanks for your answers.

If I understand correctly you are intending to charge the Air Receivers whilst at the dock and then cruise around on this stored air.

Can you please confirm if this is what you intend to do as it is not 100% clear in your post above how you intend to raise the pressure of the Air to 300 Bar.

TRY

I wish you all the best and a revolutionary efficient drive solution.

But what I know about mechanical engineering and gases & hydraulics tells me to tell you to fire your engineers. I hope I just made a wrong statement and I'm to old to understand your solution.

Hmmmm I just looked at your public profile and I made another wrong statement,you are my elder.

lets hope 2 wrongs make a right, good luck !!!

Try,

I have no doubt that your new concept runs, but at what efficiency? You are using one source of power to compress air and then using the compressed air to run another source of power. Good Luck, it sounds like you will need it.

Courious and quiet

Try,

I am one of probably many people who are just waiting for the engineering and design to be presented before commenting on the system. I am anxoius to see what you are working on and will wait untill you are ready. I am for a new propulsion design, I have done a few different ones myself but nothing like what you described.

Carry on, without innovation we have no future.

After I see more details,I can evaulate the direction your going better and maybe be able to give you advice or explanation of why or why not part or all of your design will or will not work..I do hope ,Sincerely, you are on the right track for a break thru.

Try
Can you tell me if I have this straight?

You will have a diesel engine attached to an air compressor.

The air compressor will then feed a storage tank.

The storage of compressed air will then be used to turn a genorator.

The genorator will then produce electricity to power two electric motors to propel the vessel.

It is a little bit difficult to follow the small bits of info here and there you have written. I can see how people (myself included) could be suspect to the fact of some one not being true when they lay down the info in an hard to follow spotty manner. But you have caught my interest.

Hi,

I will attempt to explain what I understand of the Air/ Electric Drive he is talking about.

As we don't know if the intended current is AC or DC I have used the terms Alternator/Generator to indicate that it could be either.

From what I understand the Alternator/Generator that will power the drive motor is itself used as a motor when connected to the mains to charge the receivers. The motive force here being electricity from the mains

It and the motors roles are reversed when what was initially the compressor now becomes the motor driving what had initially been the motor which is now converted to Alternator/Generator which supplies the electrical driving force to the motor attached to the shaft. The motive force being the air that was compressed and stored in the first stage

TRY, please don't be afraid to correct or clarify this as you have piqued many peoples interest here and we all like new and interesting ideas.

Is this what you are working on?
