This Could’ve Changed Air Travel Forever

[@MustardChannel]

Hi all - as some viewers are pointing out, it's a mistake to describe a 133 dB to 96 dB reduction as 15%. It's much more than that, as decibels are a logarithmic unit. Sorry for letting that error slip in and any confusion (note that 96dB is still incredibly loud).

[@qadarinimo258]

Can you make a video about the international space station and the Mir space station

[@ChrisPrefect]

17db reduction is almost 8 times less noise! So a reduction of about 85%.

[@CrazyHorse151]

Well it reduced the noise level by 15%. The whole reason we use dB is to use perceptually linear scales. (EDIT: sound pressure level in dB is not perceptually linear. Sone is. F*ed that up) What you wanted to express is that the -perceived- noise level was reduced by 15% and that is in fact the case. Converting to linear levels, we get a far greater reduction but who cares when we don't perceive the difference as such?

​@DT Undercover The loudness of a helicopter is about 85.5dB from 600 feet away - so if the rotodyne was to be no louder than a helicopter, it'd have to reduce its noise by 96% from the original (or 70% from the already revised version).

[@MagicznaPanda]

@DT UndercoverYeah, something like 99.7%

[@Friend_of_the_One-Eyed_Ladies]

@@MagicznaPanda SPL (sound pressure level; typically measured in dB) decreases with distance, like any other wave.

I remember the Rotodyne flying over our house! The Rotodyne was based at a small airfield called White Waltham just outside Maidenhead and as a child we lived on the direct line between White Waltham and Farnborough which was the base of the British Aircraft Establishment. On several occasions we heard the distinct sound of the Rotodyne flying over and dashed outside to watch it go over. Yes, it was noisy, but so were most aircraft at that time, especially the big jets like the Boeing 707. The difference was the big jets landed at airports outside the city centres so did not fly low over the houses, except of course the ones on the flight path into the airports. People these days forget how noisy those old aircraft were! A few years ago I heard a racket and went outside to see what it was and was treated to the sight of a Dreamliner on its way to the Farnborough Airshow escorted by a Spitfire and a Hurricane. I could barely hear the Dreamliner - the racket was all being made by the Merlins. A beautiful racket though!

I feel like this concept should be revisited to replace medical helicopters. You could deliver patients faster while burning less fuel. A lot of development has gone into miniature, quiet and efficient jet engines that could go on the blades. The larger cab size could also allow for more than one patient to travel at a time with ambulance like medical equipment and staff there for them.

[@monhi64]

Medical helicopters are a whole nother shitshow. Back when they deregulated air travel, it was generally good for the public but it left a loophole where air ambulances can charge whatever they choose. The companies behind the air ambulances realized no one really has a choice to take one or not, that’s usually up to a doctor and the patient might be unconscious so they started charging 5-10 times more than they needed too. And especially since doctors like the err on the side of caution with lives a lot of rides are both unnecessary and hyper expensive. So just to be clear the medical helicopters are not the expensive by any necessity, just price gouging lol

The financial stakeholders of airports don't care if if people spend hours travelling to airports by car, train or bus with all the additional pollution/congestion that goes with it.

A lot of crazy technology like this began in the 1950s, height of cold war paranoia. The US had planned for a state of permanent war, so the government had funded a lot of research in jet propulsion and other technology with potential military applications, and civilians benefited from this, too. Which is wonderful, but very expensive. Without a scary commie threat off in the distance, people are less willing to fund projects that may not ultimately work. Private sector outfits aren't going to risk too much on on an endeavor that may not pan out. US declined to invest in the Concorde in the early 1970s and AFAIK never seriously pursued supersonic civilian aviation again. You're right that we're stuck in a rut in air transportation for 50 years now. We have some improvement in creature comforts, but we're actually moving backwards in overall travel time. All his snark aside, Scott Adams (Dilbert Future) had an interesting explanation how airlines are stuck with minor, incremental improvements indefinitely because of the tremendous expense of converting an entire fleet of aeroplanes.

@@tonyduncan9852 Might be feasible to power the main rotor electrically since you only need a couple of seconds of thrust during takeoff.

[@tonyduncan9852]

@@h3adbang0r59 A 'couple of seconds'? Yes, but the noise would still be too much for comfort, and the thirty-ton plane could still fall on you. Why would this still be preferable to subterranean (and totally silent) transport?

Thank you for your quality content. Ever since I found you two years ago I’ve been watching your videos everyday(not even lying,I rewatch many videos). Even when you don’t post, I still watch your videos and it still gives me a new feeling. I love your goal for quality over quantity. Keep up the work no matter how long it takes and you will get a million subs FAST.

This looks like it came out right of Thunderbirds.

Actually..... you'll see 21st Century TVs interpretation of the Rotodyne in many Thunderbird episodes....

I'm willing to bet that the Rotodyne was too far ahead of it's time and probably no more noisier than any other Helicopter of it's day!

^ The irony there is that Farley was the test pilot of an infinitely louder aircraft, the Harrier 😂 . His conclusions on aircraft projects other than those he flew in [and I've read a few] are to be taken with a pinch of salt, as his actual in depth knowledge of them was limited. Case in point TSR-2. Farley's conclusion is not only incorrect from an aerodynamic perspective, but it also contradicts his former boss at Hawker Siddeley, Sir Sydney Camm. Given the respective qualifications of the two, I think Camm's verdict wins it by a mile.
