I have been asked by my peers, is it true that the small-scale prototype of the \u2018flying car\u2019 exhibited at LIMA 2019 was in fact true and not just a made-up fantasy?<\/p>\n
To answer that, and to be fair, I only made an engineering analysis on the prototype model (based on the model scale that went viral). No other information.<\/p>\n
If I was answering this in front of a class of engineering disciples, I would have to touch upon Bernoulli\u2019s Principle, Newton\u2019s Law, Aerodynamics, Aerothermodynamics, Fluid Mechanics and many more applied physics principles. I would ask my students to look into the power system, rotor size and design, vehicle design and structural integrity, materials noise and vibration analysis, manoeuvrability, control system, pay-load, power-to-weight ratio, certification and worthiness, dynamic stability etc. I would have them prove through computation fluid dynamics (CFD). But surely in this written piece I will not do the same.<\/p>\n
To appeal to the general public, the everyday reader, I will choose to merge my simple answer based on my background as a scientist, an engineer, a researcher and also as a politician; and thus I will do my best to share my opinion while eliminating scientific jargon so everything can be communicated clearly.<\/p>\n
Firstly, labelling this invention as a \u2018flying car\u2019 is provocative and sensational. Science and technology should exist on the basis of facts, not gimmicks and sensation. Undeniably, this mislabelling could lead to misinterpretation. Therefore it is absolutely crucial that those who introduced this as a \u2018flying car\u2019, the inventors and the ministry, rectify it\u2019s nickname so as to not cause mockery. That is the challenge of today. Minsters and Deputy Ministers would not do the invention any injustice to call it a more appropriate name such as \u2018vertical take-off transporter\u2019, \u2018automobile drone\u2019, \u2018drone taxi\u2019, \u2018auto hover\u2019 etc.<\/p>\n
An accurate name would be assigned based on the principles applied in launching it into the air, be it through \u2018vertical take-off\u2019 as much of the conventional drones on the market are, or just \u2018take-off\u2019 as is seen in small planes that have retractable wings.<\/p>\n
Secondly, some would ask, is it possible for such a thing to exist? Yes, principally it doesn\u2019t go against engineering and there are already vehicles that are capable of levitating at such a height such as drones that can support the load of a human.<\/p>\n
And so this begs the question, is it possible what we witnessed at LIMA 2019 would have the potential to \u2018fly\u2019?<\/p>\n
If it\u2019s construction and design adheres and obeys laws and principles of physics and engineering, there would be nothing stopping it from staying in the air. I believe the company who exhibited this has many able and talented technical specialists, but this prototype\/model still has a long way to go before it can be applicable in our daily lives. If that was the proposed design, I advise a more serious attempt to make certain it would be able to stay levitated.<\/p>\n
Had this been one of my student\u2019s projects, I would make an early comment on the bizarre design of the netting cover on the fan, which in my opinion would reduce the thrust force and power that would make it possible for the device to stay up in the air at certain heights. A critical factor is that the thrust force and power would be able to overcome the load of the vehicle and also it\u2019s pay-load (whatever the vehicle is meant to hold. Eg a human). This netting cover would only allow air to be expelled through the bottom in a uniform flow but with the consequence of reduced thrust. This would make it difficult for the device to reach a sufficient thrust power to lift it off the ground.<\/p>\n
Thirdly, in this new day and age of social media and technology, often times any government initiatives face harsh critiques from the public and other local authoritatives of all sorts of backgrounds and views. Trully understandable.<\/p>\n
Ministers and Deputy Ministers who released statements supporting the vehicle should take note that we as authoritative figures must try (and I say \u2018try\u2019 because often times \u2013 my self \u2013 it is hard to control our own emotions) to not react impulsively towards snide comments; that
\nis to not respond defensively and negatively. Take note and explain with an open heart.<\/p>\n
What if instead, we used words such as; \u201cI understand the critiques received and we have taken them into consideration to further improve said vehicle\u2019s design in the future\u201d, \u201cwe will provide a sound explanation in the future\u201d, \u201cthe technical explanation is so-and-so\u2026\u201d, \u201cthe exhibited model was just an example. The final design would be different, more refined and suitable to the vehicles objectives\u201d and etc.<\/p>\n
A quote by one fine former CEO of General Electric, Jack Welch : \u201cPeople have to trust you. You have to build in trust for people.\u201d<\/p>\n
Interesting, right? Objectives are easy to make but to make it work, now that\u2019s the real challenge!<\/p>\n
Good luck ! Benediximus !<\/p>\n
