    Question About Electric Aircraft Propulsion

    Well I'm in over my head, but in my thoughts if you can extract power for the compressor, then why not a bit larger and stronger power turbine that will cover the generators output converted to pure heat. In normal use motors and generators are governed by mechanical limits, but in this...

    Question About Electric Aircraft Propulsion

    Had a hard time deciding which post to reply to, you mention energy density of fuel and batteries, consider the efficiency of generated electricity straight to heat, almost 100% where you need it. I can't attempt to lay out a complete design, but considering the sum total of air comes in the...

    Strange optical phenomenon: lighting a candle in front of a TV screen

    This might be another example, to consider.

    Is a 10.0 earthquake actually possible?

    After reading through this article, I'm left wondering if there might be tremendous sized voids inside Earth's mantle, that if displaced in some way could allow major shifts in rock formations. Does anyone have ideas about this...

    Could you create a battery powered plane?

    Here is some good information for anyone interested in fuel/electric design, as for my thinking electric/electric assisted by wind friction of a plane in flight, is the possible holy grail. :smile: I believe the videos below are well worth someone's time to watch, should be a help in setting up...

    Air Motor Applications for Shredders and Choppers

    Here is a guide to air motors that might offer you the information you need. https://www.atlascopco.com/content/dam/atlas-copco/industrial-technique/general/documents/pocketguides/9067%2001%20Pocket%20Guide%20to%20Air%20motors.pdf

    Could you create a battery powered plane?

    This puts life into an old idea of an electric jet engine :) https://en.m.wikipedia.org/wiki/Aircraft_Nuclear_PropulsionIndirect Air Cycle Indirect cycling involves thermal exchange outside of the core with compressor air being sent to a heat exchanger. The nuclear reactor core would heat up...

    Compressed Air Engine Calculations

    A few charts here might help, I'm not sure that the motor type would make a lot of difference when evaluating flow and expansion. https://www.atlascopco.com/content/dam/atlas-copco/industrial-technique/general/documents/pocketguides/9067%2001%20Pocket%20Guide%20to%20Air%20motors.pdf

    My life changed in a way that changed my needs and I never resolved my issues, which were how to determine if my emulsion product would react to flame from a cutting torch. Depending on the type of emulsion you have, a simple steam cleaning service might be able to handle your needs (water based...

    Not sure if PF still has all his post in our history file, but if anyone has a great enough reason or desire to read thru them all, he did mention that he once was a pilot, also there was talk of some pretty serious stuff (IIRC some life inflicted and some self inflicted) he was quite...

    I suspect Danger passed away (not sure) he had made comments about his failing health and his last post his words "I now take my leave" sounded to me like he was saying goodbye in a distinct way. Someone else might have had info about him in a more personal PM ?

    Auto/Motor Centrifugal compressor lift aircraft -- engineering help please

    I ran across this a few weeks ago, I believe it might be fitting for your studies. :)

    Wood/Glass/Metal Video about modifying a new Ryobi electric hand planer

    Great video, but why am I all of a sudden missing George Carlin so much ? :smile:

    Power required to compress air in a gas turbine

    This has been my favorite link for jet engine information, hope some others might find it useful :smile: http://airspot.ru/book/file/485/166837_EB161_rolls_royce_the_jet_engine_fifth_edition_gazoturbinnyy_dviga.pdf

    Can we transfer 100% Potential energy to electricity?

    It might help to consider the first test of heat transfer from a paddle wheel to water, on turbine blades being driven by vast amounts of water the change being almost undetectable should be quite large. Just a thought.
