Hum Humm HUAM

At the AERO exhibition in Friedrichshafen a new* helicopter was officially unveiled - the tesi HUAM. HUAM is an acronym of Helicopter Urban Air Mobility.

 

The chief designer of the helicopter is Mr Mauro Piazzoli, who was a pioneer in Italy for modifying a rotorway helicopter into a turbine engine (1). Later was one of the key persons behind the AvioTecnica company which used to manufacture a ES 101 Raven helicopter (2). Later he was a chief designer responsible for the Helitek KRONO 102 (which is the same airframe as this one, but different engine) and now holds a role of a chief design engineer of the tesi’s HUAM project.

The helicopter is a two seater, with side-by-side cabin layout, with two-bladed semi-rigid main rotor and two-bladed semi-rigid tail rotor. At the first look you may see some resemblance with the Rotorway style of helicopter and based on the past experience of its designer, this is understandable. However, upon closer investigation, you will find that apart from general layout being inspired by Rotorway or Alpi Syton, this helicopter is a totally new animal, a greatest hits version of many others. I will try to explain what I mean below.

Main structure consists of a carbon fiber cabin, integrated with carbon fiber main structure and a carbon fiber tail boom. The main structure has a flat deck, like on bigger helicopters, on which a welded steel frame is attached. This frame carries the main rotor gearbox - which is a proper machined gearbox (not some belts or chains) - engine (a UL Power 350iHPs), and at its aft part the tail boom is attached. The main structure also has a 150L in capacity cargo compartment across the entire width, with doors on both sides. There are also smaller inspection panels which give access to fuel system components. Fuel tank itself is a flat one placed vertically between the cargo compartment and cockpit, below the main deck level, with fuel cap on the right side.

Power train is driven by the mentioned UL Power engine through a belt transmission. It is pre-tensioned and engaging the rotor is being done by the centrifugal clutch placed inside the lower pulley. The same pulley also incorporates an overrunning clutch. This driven intermediate shaft is placed below the engine, and to do so, the original UL Power oil sump was modified such, so it is as deep as original but placed more on the one side. This intermediate shaft connects in the front to the main rotor gearbox through a flex coupling like on Robinson helicopters, and on the aft connects to the carbon fiber big-in-diameter tail rotor shaft through a thomas coupling - like on Bell helicopters. The tail rotor shaft has one duper in the middle. In the near future it will be replaced with an aluminum one.

Control system is similar to the one seen on Rotorway - the collective lever through the push-rod moves the entire swash-plate assembly up and down, but the tilting of the swash-plate is actuated through doubled cables from the cyclic sticks assembly.

In the cabin we can find a minimalistic instrument panel, consisting of one Garmin screen and a couple of backup instruments. Pedals design is similar to Robinson helicopters. There are cabin air vents of interesting design - it is a distinct feature seen from outside on the windshield in the area next to cabin doors’ hinges. It is being opened by the yellow slider with a handle inside.

The helicopter up to this time performed 6 hovers, with the first one taking place in July of 2024. For the time being the main point of interest was the engine performance, so the helicopter is not configured and equipped with other necessary equipment like a pitot tube.

One God.

Bismillahi Rahmani Rahim.
Assalaamu Alaikum wa Rahmatullahi wa Barakatuh.

So brothers and sisters today I would like to speak about the thing that God is one, without partners or helpers. So God is only one and we, as muslims believe that God is one, He sent messengers to ppl in different times to different ppl. And all these prophets may God's peace be upon of them all. All of them spread message about one God, Who has prepared unlimited reward after death for those who believe in Him, and follow His rules and the rules of His prophets who brought the commandments of God, to humanity. And for those who do not believe in Him or choose not to follow His commandments, for those He has prepared a punishment and great torment. But this is applying only to those who have heard about the message and chosen not to follow it, so those who deny after hearing from it have the choise to follow or choose, not to follow. And those who have not heard or known about it, those God will judge differently and He knows best. And even if you are a muslim, it doesn't guarantee that you would be in paradise it is quite the opposite. Because when you know about the message, you have to work accordingly to it and if you choose not to follow it, i.e. you choose to deny the rules and limits that God has set before us. And so you are making the decision not to follow, and then you are doing prohibited things knowingly.

So there are things that God has prohibited from us, and things that are allowed to us. To put it bluntly we could say that, the things that are prohibited are things of no good. They cause hardship, sickness, evil doing, hurting someone's fellings or something that could be considered as evil or negative. And the things that are allowed are the opposite, so they are of good to us, they may heal us, they help us deal with others justly and most importantly they help us. As when we do prohibited things we cause bad to happen to us, in this life like in the next life. And the things that God has prohibited are because of something, so they are of no good to us. For an example, we as muslims are prohibited from drinking alcohol. And if we look at the modern day things we can quite well see that why it is prohibited, some ppl get quite aggressive, they cause sometimes vandalism, crime and all these things which are of no good to us, nor to those who are found as victims to it. So it is better and God even rewards us for not doing things that are prohibited, and He makes our daily lives much easier in this world too, because then we are not doing things which consume time from us. Because time is one of those things that cannot be wasted for nothing, as we all know every second is unique, we cannot take it back nor live it again. And every heartbeat is ''unhealthy'' or away from us, as that is one less heartbeat for the heart to beat. :) So we should be occupied in doing good, and forbidding and trying to prevent evil/ bad things from happening, i.e. using every second for something that is useful, which is benefitting for us and to those that we are trying to help.

So what we really should do is, to make every day worth living for. Trying to strive for the pleasure of God, so that we would be able to have our resting place in Jannah (Paradise). And that we maybe would be protected from the Hellfire, from it's torment and punishment as it is something so bad that no one would, wish it on anyone. But it is God who decides, He is going to judge us without wronging any soul as He says in the Holy Quran:

4:40 Verily, God does not wrong [anyone] by as much as an atom's weight; and if there be a good deed, He will multiply it, and will bestow out of His grace a mighty reward.

InshAllaah this writing did make you think about your deeds, and what should be done and what should not be done. And inshAllaah that we would be striving in the way of Allaah subhanahu wa ta'ala, so that we would help and make something that would benefit us. May Allaah forgive me if I may have stated something out of my knowledge. And may the peace and blessings of Allah subhanahu wa ta'ala be upon you. :)

JazakAllaah Khair.
