AIR EXECUTIVE SUMMARY

  1. The Pitch

In the Aviation Industry we can cut jet fuel costs in half with engines which cost only 15% of the engines we replace. We have a simpler, lower maintenance, lighter, less costly, high efficiency engine, patented.  It runs on any engine fuel, produces less CO2 and saves money on fuel.  It is Tomorrow’s Engine in fact.

  1. The Problem

Airplane engines have not improved significantly in more than sixty years.  They use a form of kerosene as fuel, priced around 90% of the price of gasoline.  Kerosene produces 104% as much CO2 as gasoline. The US Carrier airline fuel cost in 2015 was  $30.798 Billion for all flights.

See:  http://www.transtats.bts.gov/fuel.asp

  1. The Solution

Our engines operate at over twice the efficiency of gas turbines, so they will operate as jets using less than half the fuel used by gas turbines.  Our simpler engine can burn any clean burning fuel, resists greater acceleration than gas turbines, is lighter, requires less maintenance, and is less costly.  Our engines could have saved airlines $16.015 Billion if used for all flights  in 2015.

  1. The Opportunity

Our engines are the first great efficiency advance since the turbine, and are patented.  They cost only a small fraction of turbines.  Hence, we suggest leasing our engines while the patents last for 75% of the fuel savings they produce.  In 2015 this would have saved the US Airline Industry $4 Billion.  They also reduce CO2 production in the same proportion as costs.

  1. Our Competitive Advantage and Business Model

Nobody can believe that airplane manufacturers and other engine manufacturers haven’t tasked their designers with finding higher efficiency engines for 100 years.  Anyone who thinks it was easy to double the best engines efficiency just hasn’t been paying attention.  Significantly raising our engine efficiency, which is theoretically up to 90%, is no longer possible and is not expected in the next hundred years.  That’s why we call this Tomorrow’s Engine, because it may never be beaten.  While our patents last, and that includes the design patents for mechanical engineering design yet to be applied for, nobody but us can provide the fuel savings we provide.  Our business model provides the engine at no cost other than installation to the airlines and makes airlines a profit over their previous operations whenever the engines are used.  This will become an easy sell as time goes on.  We are offering a 40% interest in the company for the small investment of $5 Million.  The anticipated company valuation in 10 years is  $128 Billion, an ROI of 25,600.  The exact efficiency of the engines will only be known after testing and building prototypes, which are already designed.

  1. The Team

We will accept an investment from a VC who can staff the firm.  All the current principals will be advisors or Board of Director Members at most.  We will advise but we will not manage the operation.

  1. The Promise

We will determine real efficiency of our jets for less than $100,000Our business plan is hard to dislike on the customer side.  We are offering to simply make money for the airlines with every engine they lease.  We recommend that our first sales be single engines for planes with four or more engines, or, in other words, planes which can fly without using our engine.  Turbines fail rarely, but they do fail.  In domestic air travel approximately 117 turbines fail per year.  Having several engines makes these failures routine rather than crises.  We have no track record to say we will fail less often than turbines, although the simpler design suggests we will.  Flying hours is the only proof of reliability. If our engine is one of four, it’s failure is also routine and not a crisis.  It would take a high rate of failure we do not anticipate to make the airlines not want to use the engine.  In a few years the reliability will be well known.

  1. The Ask

$200,000 for the option to purchase 40% of Tomorrows Airplane Engine LLC, which has all the aviation rights to Tomorrow’s Engine LLC patents, for $5,000,000.  The $200,000 will be used to prove the practical efficiency of our jet engine for different engine options, and to maintain patents.

How Tomorrow’s Engine Works

How Tomorrow’s Engine Works

INTRODUCTION

Tomorrow’s Engine, as described in this article, has many unique features.  It is a constant RPM engine.  Top speed of parts in the engine is supersonic and independent of size, making small engines rotate with very high RPM.  It is capable of high efficiencies (possibly up to 90% with existing materials and manufacturing techniques).  Gas temperatures in contact with moving parts of the engine are up to 500K below gas temperatures in contact with moving parts in other engines.  This is possible because more than half the energy added to the gas and removed from the gas by moving parts is kinetic energy from supersonic gas.  It has few parts and is thus lightweight, delivering more power than other engines (even turbines) of comparable weight.  The hottest parts of the engine do not require cooling.

The Fundamental Difference Between a Turbine and Tomorrow’s Engine

    Both a turbine and Tomorrow’s Engine impart energy to gas through rotation.  A gas turbine drives air axially, and is driven by axially moving combustion products.  In a jet engine air enters and leaves on roughly the same axis.  Tomorrow’s Engine incorporates two roughly pyramidal rotors and the hollow shaft inside those rotors into components we refer to as “spinners” which contain the circulating gas flow and force it to match their rotational speed.  One is the compressing spinner which contains the gas flow as the gas travels away from the axis, accelerating it circumferentially to add energy.  The other is the power output spinner which contains the gas flow as the gas moves toward the axis, decelerating it circumferentially to take off energy.  Each spinner is a rotating container with separated roughly radial pathways for the gas to travel through radially, which will be accomplished by radial holes through shaft walls or passages defined by radially oriented blades and walls.

What Tomorrow’s Engine Looks Like & How It Works

The engine consists of a long shaft on which are found the roughly pyramidal compression spinner and power spinner.  While the compression spinner does all the work needed for compression, producing supersonic rotational speed , most of the compression takes place outside the compression spinner as the supersonic gas slows down, first to subsonic speed in a surrounding ring called the compression annulus, and finally to least speed in the heating chamber.  The compression spinner and annulus are smaller than the power spinner and annulus.  After the compression spinner adds energy by circumferentially speeding up the moving gas, additional heat energy is then added at constant pressure burning fuel.  This energy is converted into rotational power in the power spinner by the moving gas in a time reversal of the compressing spinner in larger parts at higher speeds.

The supersonic gas, slowed down by the power spinner, drives the rotary motion of the shaft.  The rotary motion of the shaft both drives the compression side of the engine, and does work outside the engine itself because the shaft is connected to outside equipment, usually an electric generator which also acts as the starter motor.

Fig. 1M

                                                                          Fig. 1

Figure 1 shows the shaft with the spinner blades attached.  The thinner section of the shaft is for the compression spinner, and the thicker section of the shaft is for the power spinner.  Radial holes in the shaft (not shown) are part of the spinners.  The shaft is solid between the spinners.

A key feature of the engine is the temperatures the moving parts experience, which are considerably lower than corresponding temperatures in piston engines.  The parameters used are the following.

T0 = atmospheric temperature in degrees K

R1 = radius of compression spinner

R2 = radius of power spinner

γ = polytropic constant

SoS = speed of sound

α =R2/R1

ω = angular velocity of shaft

R = radial distance from shaft

The temperature inside the compression spinner at radial distance R is given by

Eq1a

The temperature inside the power spinner at radial distance R is given by

Eq1b

                                                                  Fig. 2

Figure 2 shows the shaft and the spinners (blades are inside the spinners), and the basic flow of the gas through the engine is indicated by arrows.  Red arrows indicate that the gas is heating, blue arrows indicate that it is cooling.

The Compression Side of the Engine

The gas enters the compression spinner and travels outward while rotary motion speeds it up.  The shaft turns very quickly, so that before the gas reaches the rim of the compression spinner, it is rotating at supersonic speed, which also heats the gas. The gas then emerges from the spinner into the compression annulus, designed to slow the gas down to subsonic circular speed and convert its energy of motion into heat.  The gas spirals outward a few times around the annulus before entering an exit vent and reaching final compression in a heating chamber.

The Heating Chamber

The heating chamber is sized to make the subsonic flow from the annulus slow to far below the speed of sound in the hot gas, converting almost all the kinetic energy of the gas into temperature energy.  The gas slows in the heating chamber and reaches its maximum compression temperature.

Fig. 5M

                                                                 Fig. 3

Figure 3 shows the stationary annuli surrounding the rotating spinners.  These are open rings that high speed gas spirals through, outward in the compression annulus and inward in the power annulus.  The gas is supersonic next to the rotor and subsonic at the outer rim where vents collect the flow into subsonic tube flow through connecting tubes.  Flow is reversed on the power side.

                                                                 Fig. 4

Figure 4 shows a cross-section of the engine showing shaft, rotors, and annuli.     After reaching maximum compression temperature, additional heat is supplied by burning fuel.  This gives the gas the extra energy with which to do work outside the engine.

Fig. 8M

                                                                    Fig. 5

Figure 5 shows the configuration of the entire engine, with the heating chamber located in the center, connected by tubes to each of the annuli.  The shaft and the spinners turn, but the annuli, heating chamber, and connecting flow tubes are stationary.

Using the previously-defined parameters, the temperature in the compression annulus at radial distance R is given by

Eq2a

The temperature in the power annulus at radial distance R is given by

Eq2b

The input stagnation temperature Ts1 in the heating tube is given by

Eq2c

And the heated stagnation temperature Ts2 in the power annulus is given by

Eq2d

Beyond the Heating Chamber

The gas now goes through a process in the power section of the engine which mirrors in reverse what happens in the compression section, with larger parts at higher speed.  After the gas has been completely heated, it goes through a speed-controlling vent at subsonic speed into the power annulus, larger than the compression annulus, which surrounds the larger power spinner, where the gas spirals inward.  The gas speeds up in the annulus to supersonic, like air speeding up going into the bottom of a tornado, and matches the speed of the power spinner as the gas enters it.  The gas is slowed to the rotational speed of the spinner which turns the shaft, and then emerges as exhaust from the right side of the shaft in Figure 4.

Although the current version of the engine is an internal combustion engine, the design can be used to create a high-efficiency engine powered by solar heating.  In order to achieve efficiencies of 80% or higher, the engine will be constructed of ceramics rather than metal, and will be powered through external heating of argon to reduce pressures and stresses.  The entire engine will be self-contained to enable the argon gas to be recirculated from the exhaust to the intake, where it will be used again.  In a solar version of the engine, the heating chamber is the heat collector inside a box receiving the collected sunlight.  Ordinary atmospheric cooling in shaded pipes, water cooling, or a heat exchanger may be used to cool argon exhaust back to atmospheric temperature before it is returned to the engine.

Engine May Offer Sustainable Clean Energy

HIGH EFFICIENCY FOR A BRIGHT FUTURE

Tomorrow’s Engine is a new type of engine with a theoretical efficiency of up to 80% verified by a gas dynamics expert. See details in Posts on http://TomorrowsEngine.com.  A 75% efficient engine will more than double the power generated from the same amount of fuel consumed by a gas turbine.  The engine is ready to be built and tested.

Why should you care if this engine has high efficiency?

  • This high efficiency engine will reduce engine-produced CO2 by more than half, reaching the 2030 Paris goals in half the time. This will lower home and business electricity costs substantially.
  • The alternative currently being studied by politicians is to impose CO2 penalties and taxes, further slowing the economy and raising your bills.
  • This high efficiency engine will allow the US to stop being an importer of oil, saving the US economy $400 billion annually. This is money left in your pocket.
  • This high efficiency engine enables a new storage method for solar power – manufactured fuel. Manufactured fuel costs too much using engines with low efficiency.
  • Solar power has been avoided because it is not available on demand, and because storing and transmitting  power is expensive or difficult. Manufactured fuel makes it possible to store the energy created from solar power.
  • Solar power can be used to turn fast growing biomass such as algae or grass into fuel for transportation. The use of such manufactured fuel is carbon neutral.
  • While people may want fossil fuel to go away, fuel is not going away so long as airplanes fly, ships sail, and rockets blast off.
  • Fuel manufactured using solar power offers a world a preferable alternative to fossil fuel which will not increase atmospheric CO2.
  • Energy rationing will not be needed because solar power is abundant.
  • This approach ends global warming and achieves sustainability through efficiency alone,

Think it over.  If successful this engine will stop global warming while saving the average American over $3,650 per year.  A gain of $10 per day per US citizen is HUGE.  It’s enough money to pay down the National Debt.

Holding back these rewards is the fact that developing the machines to build and test is a small cost if we were a BIG company.  But we’re not, and these costs are enough to stop our small start-up company from building and testing this engine. Every day these tests are held back costs the average American over $5 in gains delayed another day, costing the country over $1.5 Billion a day. This is unnecessary and avoidable.

Let’s start cutting our losses by getting these benefits to you and the economy. Share this message with your friends and help us raise the relatively small amount of money necessary to build and test the engine.  We expect the engine to succeed, to show never before reached engine efficiency, as it is designed to do.  These gains will revitalize economies.  Write us a check today and you and future generations will be the winner.
