Conceptual Design Amphibious AI Rescue Aircraft Series (GLARE Trimaran Hull & Battery Electric Prop)

Това ми затруднява разбирането какво предимство предлага вашият летателен апарат. Ако хеликоптерите вземат ранени, защо да ги транспортират? Всяко прехвърляне е рисковано. Всяко прехвърляне отнема време и гориво, докато хеликоптерът се рее във въздуха. Ако възнамерявате вашият летателен апарат да предлага медицинско оборудване и услуги, които хеликоптерът не може, какво го прави по-способен да превозва този товар? Ако възнамерявате вашият летателен апарат да предлага по-бърз транспорт от хеликоптера, тогава всяко спестено по този начин време трябва да се компенсира с времето, необходимо за прехвърляне, и времето, необходимо за прехвърляне от мястото, където вашият летателен апарат каца, до болница. Ако болницата има хеликоптерна площадка, хеликоптерът не се нуждае от това прехвърляне и би спестил общо две прехвърляния - от хеликоптера до вашия летателен апарат и от вашия летателен апарат до линейка.

Дори ако вашият летателен апарат е по-бърз от хеликоптер, колкото по-далеч трябва да е той от мястото, където се качват ранените, толкова по-малко време може да спести. Ако вашият летателен апарат може да носи оборудване, което хеликоптер не може (макар че тогава може да е по-рентабилно да летите с по-големи хеликоптери, отколкото да комбинирате малки с вашия летателен апарат), колкото повече време отнема да стигнете до вашия летателен апарат, толкова по-малко предимство има в сравнение с директното отиване до болница.

Първоначално си мислех, че искате да вземете жертвите директно. Ако очаквате да разчитате на хеликоптери за първоначалното вземане, вижте по-горе. Доколкото искате да вземете жертвите директно, един пример би могъл да бъде илюстративен.

Важното не е разпределението на състоянието на морето във времето, а разпределението на жертвите по състояние на морето. Някои жертви могат да се случат в гладко спокойно море, но бурното море ги прави по-чести поради падания и повреди на оборудването, дори потъване. Поради липса на статистика, ще измисля някои числа, които можете да коригирате, ако имате данни за предвидения от вас район на действие.

Използвайки кода за състоянието на морето на СМО ( Sea state - Wikipedia https://en.wikipedia.org/wiki/Sea_state#WMO_sea_state_code ), да кажем, че жертвите са разпределени, както следва:
Състояние на морето 0:2
Състояние на морето 1: 3
Морско състояние 2: 5
Състояние на морето 3: 8
Състояние на морето 4: 12
Състояние на морето 5: 18
Състояние на морето 6: 22
Състояние на морето 7:16
Състояние на морето 8: 8
Морско състояние 9: 6

Доколкото мога да преценя от няколко видеа, спасителите от хеликоптери могат да вдигат хора от водата до състояние на морето 7, така че в обсега си те биха могли да вдигнат 86 от 100-те жертви, посочени по-горе. Ако вашият плавателен съд може да се приземи само до състояние на морето 2, тогава вашият плавателен съд може директно да вдигне 10 от 100 жертви, при условие че са в морето. Ако има спешен медицински случай на кораб в гладко спокойно море, хеликоптерът може да го вземе директно от кораба, докато вашият плавателен съд ще се нуждае от спускане на пострадалия. Колко кораба са оборудвани за това?

Като цяло, самолетите с фиксирани крила предлагат по-голяма скорост и горивна ефективност от хеликоптерите. Използването на батерии с по-ниската им енергийна плътност поне намалява това предимство.

В обобщение, не ми е ясно какво предлага вашият летателен апарат на службите за търсене и спасяване, че да си струва разходите. Очевидно те така или иначе се нуждаят от хеликоптери. Ако приемем фиксиран бюджет, спасителната служба ще трябва да намали броя на хеликоптерите и да преназначи персонал към вашия летателен апарат, който би бил по-чувствителен към състоянието на морето, просто защото трябва да кацне, а нископланът го прави по-чувствителен. Като се има предвид това намаление на броя на хеликоптерите и спасителните плувци, които са ви необходими за първоначалното вземане на кораба, как вашият летателен апарат помага?
Dear Mr. Robert,
Perhaps it is time for you to stop enthusiastically painting apocalyptic pictures and start looking at the actual facts. The truth is, I would never allow the design I proposed to the esteemed readers to land in unsuitable locations—such as the very depths of war or, metaphorically speaking, "in the eye of the storm." That would be like deciding to land a rescue amphibian near an erupting volcano, strongly believing that the lava would simply bypass it. Yet, who knows—after all, every rescue mission has a headquarters with a commander coordinating the rescuers' actions. Thus, someone might indeed decide to position the command headquarters closer to the ongoing events, precisely by utilizing such "small amphibious aircraft for emergency medical assistance, supply, and evacuation."
You must also accept the fact that I have never stated in my comments that the wounded should be transferred from large rescue helicopters into small amphibious aircraft. The designs I am proposing are meant to serve auxiliary functions, precisely defined by the rescue mission's headquarters.
You are correct that I do envision a direct water landing, opening the nose section of the aircraft, and taking in casualties from inflatable boats with the assistance of Navy SEALs (or maritime commandos). However, I will always repeat this "but"—only if the sea state and wind conditions are within the permissible limits previously calculated for the specific area the amphibious aircraft was designed for!
Sincerely,
Rabah

In my response to Blue Bell, I have already explained why there is currently no need for me to conduct a study on the necessity of such amphibious emergency medical service (EMS) aircraft.
Your question would be more appropriate if it were formulated in the following way: not whether they are necessary, but how many units should be built for the specific rescue service! However, an answer to this question is only possible after the construction of the first experimental prototype and, most importantly, after its successful testing.
Why are you designing something there is no need for? Unless you make a study that shows a need, this is an exercise in futility.

Gonzo, I’m sorry, but I cannot show proper respect to people who twist my words. Can you point out any text in my comments where I stated that the aircraft I am proposing are not needed?
I said, and I repeat my answer to your inappropriate question: There is absolutely no need right now / at the present moment / for me to address the question of whether such aircraft are necessary.
But you are not following the comments at all, otherwise you would know that this question was already raised by Blue Bell, and I have already answered it.
And one more thing—stop trying to lecture me on how to organize my work on this design! I simply see no value in your comments. You would be better off focusing on publications where you feel more in your element.
I do not intend to answer any more of your provocative questions in the future!

Dear Blue Bell,
[...]
Your comment that this is not an aerospace forum should be directed to the forum moderators, not to me, as there is a specific section here named "Hydrodynamics and Aerodynamics". Why do you think aerodynamics should only apply to the sails of sailing yachts, but not to a hydroplane with a trimaran construction?
Aircraft need to be designed with stability issues in mind that don't apply in the same way to boats. A fixed wing aircraft may go into a spin. It's stabilisation in pitch and roll while in the air is different from that of most boats. You will need to talk to aircraft designers about those aspects of your design.

You must also accept the fact that I have never stated in my comments that the wounded should be transferred from large rescue helicopters into small amphibious aircraft.
I got that impression from your reply on the 22nd:
I have already commented on this issue before. Initially, the "heavy artillery" is sent to the disaster zone—meaning Navy SEALs or rescue teams in large helicopters, who deploy inflatable boats and winch lines. These rescue teams will secure the people in distress and transport them to the safely landed amphibian aircraft.


You are correct that I do envision a direct water landing, opening the nose section of the aircraft, and taking in casualties from inflatable boats with the assistance of Navy SEALs (or maritime commandos). However, I will always repeat this "but"—only if the sea state and wind conditions are within the permissible limits previously calculated for the specific area the amphibious aircraft was designed for!
You have made that clear, and I have not disputed it. I argue that:
1) When a flying rescue craft must touch down to do its job, then the greater the restrictions on where and when it can touch down the less it can be used.
2) Your design with its low wing seems to be more restricted than others.
3) Rescue services would have to finance buying and operating your craft from an existing budget, so would have to cut down on other equipment and personnel. I have asked what your craft offers that would justify cutting down on other equipment and personnel. I expect your potential customers will ask themselves and possibly you that same question.
 
I think Gonzo may have said it best:
this is an exercise in futility.
Best of luck to you Rabah, being a humanitarian and rescuing people in distress at sea are noble endeavours but your approach is questionable at best.

Dear Robert,
We have different perspectives regarding my publication. However, this does not mean that I agree with you! We diverge on three specific issues:
The first issue—which you were actually the first to mention, and which was quickly adopted by Blue Bell and gonzo, who immediately chimed in that if this is not implemented, further design is pointless—namely, the SOR (Statement of Requirements ) issue, does not concern me at all at the moment, because I first need to refine the proposed design. For me, this is of paramount importance.
The second issue where our views differ is the following: Before a design can fly, it must first be able to move on water with increasing speed, during which the bow begins to rise due to the generated hydrodynamic lift—meaning it must operate in planing mode. Therefore, hydrostatics and hydrodynamics come first. Let us briefly mention the primary laws:
a) The lower the design's CG (Center of Gravity), the better the initial stability at small angles of heel (up to 10 degrees), because we have a higher value of initial metacentric height;
b) At large angles of heel caused by wind pressure, a lower CG increases the righting lever (GZ) in the static stability curve, making the righting moment greater than the heeling moment. Consequently, low-mounted wings, which are the reason for the low CG (as they contain volumes that can accommodate medical and other supplies), favor transverse stability in heavy seas and high winds.
The third issue we disagree on is your assumption that the design will be built and deployed immediately. But you are mistaken! I stated very clearly at the beginning of my publication that these amphibious rescue aircraft will not use liquid or gaseous fuel for their engines, but electricity only. Therefore, this is not about competing with previous aircraft designs at all—nor is it about budgets or constraints on available personnel to maintain them. Considering that I propose using AI instead of a human pilot, and knowing that AI will continue to be refined for a long time before it can be fully trusted, it appears that your comments address the current situation, whereas I am looking to the future.
Sincerely,
Rabah,

If you have no SOR and have no concern about requirements, what is that you are refining? No SOR = no proposed design.
