[@bryanflanagan2905]

I'm wondering where the benefit is in making this hybrid. My understanding is that every conversion of energy type results in a loss, that no conversion is 100% efficient. In this case only about 30-40% of the energy contained in the petrol would get through to the prop, the rest is lost in waste heat, friction, pumping and probably other processes. If we then take some of the mechanical energy from the crankshaft and convert it to electricity in the alternator there will be another energy loss, how much I'm not sure. Alternator to battery - another loss. Here I'm assuming that the alternator can't generate electricity and function as an electric motor at the same time. Battery to electric motor - another loss. Electric motor to prop - another loss. In a hybrid car a pretty good percentage of the efficiency is the result of the capture of some of the vehicle's kinetic energy as it slows down which is part of the reason why we are seeing so many "mild hybrids" - very simple hybrids with a tiny battery which realise something like 10-15% fuel saving simply and only by recouping much of the vehicle's kinetic energy as it slows down. Whilst there is potential for aircraft to recoup some kinetic energy on descent the operating pattern of an aircraft tends to be take off, cruise, descend whereas cars tend to be very much on/off the gas, giving plenty of opportunity for regenerative braking. Please understand that I am not trying to rubbish this concept, my best wishes to Aeromarine for this interesting project. I'm simply curious as to where the benefit accrues.

[@quidestnunc9238]

ICE have been lame engineering from the times of Mr. Benz in the 19th century. Electric and Steam motors were problems because of weight, as was Diesel [more accurately known as compression ignition engines or CIE]. Purportedly, Hydrogen-Electric is the preferred motivator for quiet, low-emmissions (spelling?) Propulsion. We shall see.

[@Enlightenment_2025]

Yes, this is what I thought, too. Think of an air conditioner. I would have used a turbine in the end of exhaust gas pipe like a turbo charger.

[@benbosma]

@@quidestnunc9238 The hybrid application is real. The target platforms are UAVs both fixed-wing and rotary-winged quadcopters. In the fixed-wing scenario, the extra boost is used to takeoff and climb to altitude and then the motor is turned off and converts to a generator to operate the onboard sensors. In tandem the motor and IC produce about 120hp which is necessary to get some of these platforms in the air. When they get to altitude the airspeed is slow because they fly at min sink speed to maximize endurance. This is where the .95gal/hr comes in vs 2.4gal/hr of a 120hp engine at those low power settings. The quadcopter application is a little different. Four hybrids on the corners as IC engines aren't responsive enough to maintain "balance" or fine maneuvering and it's all fine maneuvering for a quadcopter. The BLDC motor is very responsive and provides a very slight thrust component but 100% of the control component. There are examples of hybrid quadcopters flying already. I don't think I'll sell a single hybrid to a manned application but the UAV market is huge!

[@dcacklam]

Sorry, but you are entirely wrong for aircraft. Power-to-weight ratio is key when you want to fly, and none of the other options come even close to working on an aircraft - especially an ultralight. The rules for cars don't apply to planes - which is why diesel aircraft are extremely rare and extremely expensive.

[@dcacklam]

@@benbosma Except that the weight of the batteries will detract from aircraft performance, vs a more conventional power-adder (turbo) that can be used for takeoff & wastegated out-of-action for cruise....

[@KevinArmstrong4154]

This is excellent news, they're using the redrive I'd drawn up on CAD with Ace Aviation-John Penry-Evans's manufacturing help from his Indian factory, Chip's talking about hybrid but I'd stay with the clean burning lightweight original to save weight. Same engine on G-KEVA but his inlet manifold is low profile, do fancy nicking that engine mount design as it's a lot less clumsy than my version. This video is the test with the 25 row wider belt. Took her to 10k feet and the EFI means no mixture change at all. This is great, lots of ideas to steal 😉 here's a test flight:-kzbin.info/www/bejne/lZrUp4utbauggMU

[@benbosma]

Hi Kevin, A big shout out to you for your help on this. We did have to do some things with the design to get a more compact arrangement since we are using the low riding intake manifold. My focus is the hybrid but it will certainly fly as a straight V-Twin a lot more than it ever will see the hybrid configuration. Another aspect of this program is we're working directly with the engine manufacturer and don't have a go-between or distributor. When Chip says there are a lot of them I can verify that last year there were 35,000 engines imported into the USA alone. Not all were the 800cc version, but they were a big percentage.

Once again, car things like 'hybrid' propulsion do not apply to planes. Especially ultralights, with a 254lb empty-weight limit (there is no weight-exception in the law for batteries). In a car, your engine is operating to produce short bursts of power, followed by long periods of low output - and when you slow down, a hybrid system can convert that energy into electricity. In a 60hp plane you are running 100% power for takeoff and landing, then 75% power for cruise. Any power spent charging (very heavy, compared to gasoline) batteries is power that doesn't get turned into thrust... There is no 'low speed/high-torque' energy savings from an electric motor in an airplane (The way there is for a car in city traffic), and no method of recovering expended energy (no brakes in the air).

[@mr-uc4me]

Dan brought up part 103 for some reason, but this engine isn't intended for part 103 ultralights. As far as regeneration in an airplane, it can work and can extend duration in certain situations (like training -circuits- see Pipistral) but not so much on cross countries. Batteries can't meet the energy density of gasoline, but they don't have to - electric motor 95% efficient vs typical gasoline engine at 20% means the battery only needs to supply about 25% of the energy equivalent. It's why a Tesla can go 300mi on the energy equivalent of 3gal. of gasoline.

[@IhabFahmy]

Not exactly an accurate statement.. Aircraft do have a requirement for "short bursts of high power" during takeoff and climb. Then there is an extended period of "lower power requirement" during cruise. The hybrid concept applies perfectly.
