Old Army helicopter pilot here. Autorotation is life! The drone style ships scare the heck out of me. They have no inertia. When the blades stop you are in big trouble. I like your project. Keep up the great work guys! 👍

@stevemyers2092 9 месяцев назад

2 things I want to ask you. 1) how will the battery weight affect how a rotary wing pilot would auto-rotate compared to an R22/44 Bell Ranger etc. 2) would it benefit from being able to jettison those battery packs with a pull down leaver (like the ballistic chute) IF there was a problem and the pilot had to auto-rotate? (Can put GPS transmitters in the packs to find them on the ground afterwards).

@gregbacon819 8 месяцев назад

Both of your questions are weight related. A unique feature of electric aircraft is that the weight doesn’t change over the course of the flight, so an autorotation in the electric helicopter would be closer to the max gross weight as compared to an autorotation in a liquid fuel powered helicopter that has burned off a significant amount of fuel. From a flight characteristic standpoint, the autorotation glide ratio increases as the weight of the aircraft decreases. So, the liquid fuel powered aircraft would gain glide ratio as its fuel is consumed over the course of it’s flight. That glide ratio increase would be aircraft specific and difficult to estimate, but yes, the additional glide ratio could be helpful in some situations. However, the idea of jettisoning a part of your aircraft with the intent of reusing it brings up a host of concerns; design complexity , reuse condition, risk of injuring people and property on the ground, etc. As an engineer that dabbles in the homebuilt aircraft space, I believe in building light, simple, and economical. I would forego the battery jettison feature as it runs counter to those design principles.

@user-jq2rf4nf3o 8 месяцев назад

helicopters at gross weight auto better then at empty weight , Power is stored in weight power in = power out An external load can be released only change will be collective position At altitude of 13,000 ft you need to remember not to dump your collective or you'll over speed the rotor system .

@@feelincrispy7053 Thanks, well I was thinking after multiple flights since right now the only thing holding it in is the socket connection pinching pressure, but after many cycles just like a plug and a socket The connectors will become polished and a little bit smoother and have less grip to hold the connection into the socket on their own.

Back in the early 2000's I was part of the crowd that brought brushless motors to RC (CD Motor Works). We could taylor our torque to the application by running different sizes of wire and windings on the poles as well as the number and spacing of the magnets. I would calculate the needed RPM of the motor and tailor the motor windings, wire size and magnet configuration to that RPM. Same motor could be 40,000 RPM or 3500 RPM based on the configuration. 3500 would swing big props, 40,000 would work well in ducted fans.

@chriswilliams8607 8 месяцев назад

Yes, they are going to improve a lot, serial production has started for 500Wh per kg battery weight, which is double what's currently used in EVs, and research shows that at least 1kWh per kg will be possible, it might be even more, some labs expect even 1,5kWh, which would push small electric planes into 2 to 4 hours endurance. Helicopters will be unfortunately much more limited, but if one hour or 90 minutes can be reached that would be pretty perfect for flight training or short fun flights.

A lot of stuff compares well with an rc helicopter, like the rotor has to run free from the motor during auto rotation, even more important when you only have a meter or two (or less) of rotor to bring you down safely. Also the separation of the power circuit from the rest is a common practice in bigger rc helicopters.

@gregbacon819 7 месяцев назад

This helicopter, like all helicopters, do have a way to glide down safely, and it is a flight maneuver referred to as "autorotation". If the electric motors were to stop (for any reason), the sprag clutch between the electric motor and the rotor system allows the rotor system to continue rotating, both main and tail rotors. As the aircraft is descending without power, the air going through the main rotor provides the energy to maintain a flying rotor speed. To explain it from and energy standpoint, a helicopter at any altitude has potential energy. The higher the altitude, the higher the potential energy. During descent, the potential energy is converted to kinetic energy, and this is how the rotor system maintains adequate rotor RPM. As such, a higher altitude is safer as you have more potential energy to use during an emergency landing. At one time, the Bell 206 Jet Ranger had the distinction of being the safesty "single engine" aircraft in the world. I don't know if this statistic still holds true. I'm sure this helicopter can operate as safe as an engine driven helicopter provided reliable and intelligent power monitoring equipment, good batteries and motors. I'm looking forward to more updates on the development!

@impuls60 8 месяцев назад

Put a big sprocket on the main shaft under the cabin and run the motor at the bottom. No need for belts and get all the weight down low. High spinning motors are a lot more powerful with better efficiency too. I'd put 2 motors in the tail boom like an rc helicopter to save complexity, and then you could have some batteries in the tail boom. Getting rid of the transfer shaft will save a lot of complexity and weight. With the right programming of the tail motors it fly bulletproof no matter the pilot's mistakes. WIth a some accelerometers you'd soon get heading holding etc working when the stearing already is electric.

@moteroargentino7944 8 месяцев назад

A sprocket would almost definitely be much heavier than a belt. As for the tail rotor, two motors (plus their cooling systems and controllers) are both heavier and more expensive than a single shaft. Not to mention that with one motor, both rotors are synced. So a power lose affects both of them, keeping stability. But if your tail motor failed for whatever reason, the whole helicopter would *instantly* become incontrolable. Very dangerous.

@tannerbean3801 7 месяцев назад

This would be such a rad job. I don't know what kind of tests or qualifications you guys will need in for aircraft worthiness of all the components (especially the main rotor inverter)... You are likely already aware of the Dana/Hyper9 inverters, which allegedly use SiC MOSFETs in the power stage, for optimal efficiency and thermal mgmt. I think most of these standalone EV inverters are conduction cooled, but you can easily attach them to a custom water cooled plate. If you find the right supplier, they could perhaps mill passages on the underside of the cooling plate for copper tubing, before assembly (So you don't have 2x as much Aluminum as is necessary). Did I hear rumblings that you have separate motors for the tail rotor and main rotor? A Prius (or other models from Toyota/Lexus) Inverter-Converter might be a suitable inverter. They are liquid cooled, rather high power depending on the year & model, a built in 12V DC-DC converter, one motor output is lower power than the other, and a high power bidirectional DC-DC converter which could be used for battery charging (on the GS450h, it is a 30kW converter). They are CAN-BUS controlled.

@bobrob2917 2 месяца назад

Can the rotor motor be located inside the rotor head to remove transmission & other redundant parts? I assume the tail rotor can be direct electric drive also. Apparently there are solid state bending systems that can replace yokes & lever arms in rotorhead. I imagine 45 mins run time / range will be the threshold for viability so they can be used for flight lessons. An efficient thermal system will be key, part of the edge tesla has over their competitors. During charging the thermal equip can be supplied by the charger, so the capacity isn't ermanently on board.

print out some light weight aerodynamic covers for the battery packs once seated inside you can pull the last one in to you that will stop most the drag if done right.

A main fuse that can potentially fall off and a master power switch from west marine??? Is the motor from the hobby store?

Chute🤔Twin main blades, floats for water application? Great work team.

The main fuse is held in by a "that ain't going nowhere" and prayer.😂

Can anyone explain why they would use some of their limited amount of electricity for powering a fan to pull air through the radiator when they could just place the radiator level and let the rotor wash blow through it.

How secure is that fuse or switch at the floor. If the fuse comes loose from vibrations or you accidentally hit that switch, you will fall out of the sky. Also that rotor is dangerously low. But awesome project. What is the estimated flight time? You have a massive cooling rotor, so why use liquid cooling or even that small fan, it’s just extra weight.
