Mitsubishi Advanced Technology Demonstrator - Experimental (ATD-X)

[Marechal-do-ar]

Além de grande e caro pra caramba...

Mas é primeiro mundo, as coisas lá funcionam um pouco diferente, ao invés de colocar requisitos facilmente alcançáveis, eles colocam requisitos quase impossíveis de serem atingidos e depois relaxam os requisitos conforme os engenheiros apresentam dados mostrando a impossibilidade de atingir tais metas.

[FCarvalho]

Eles precisam de algo que seja capaz de enfrentar J-20 e J-31, e mais o que vier depois disso. Os chineses são pródigos em desenvolver novas tecnologias para sua força aérea e marinha.
Aliás o TO japonês é essencialmente aeronaval. Portanto, qualquer coisa que voe por lá tem de ter capacidade de operar sobre o mar em missões tipicamente da AN, mesmo que sejam caças da força aérea.
Estes requisitos buscam aninhar em uma mesma célula capacidades que fazem com que ele possa ser operado tanto pela força aérea como presumivelmente pela aviação naval nipônica.
Ou alguém acha mesmo que um Nae na armada imperial não é só questão de tempo?

Isto foi apresentado dia 14, tem algumas coisas interessantes o motor XF-9 parece que vai copiar o sistema russo de vetoração de empuxo. a estrutura interna da fuselagem não vai ter rebites para diminuir o peso em 10%, os motores vão ter uma proteção extra em volta dentro da estrutura para resfriamento.

[FCarvalho]

É, falando em tecnologia avançada, o Japão parece que definitivamente deixou para trás os seus mais que regrados óbices ao uso militar dela. A competição vai ser acirrada.

Que o mundo seja o grande vencedor desta corrida transloucada pela supremacia tecnológica.

DMU 25 (2013)


DMU 26 (2014)

Parece que colocaram CFT para ampliar o alcance.



Se sabe que existe o DMU 27/28/29 (2015/2016/2017) porem eles não divulgarão nenhuma imagem.

http://www.cavok.com.br/blog/proximo-ca ... nt-page-3/

O desenho do DMU26 acompanha os estudos feitos do DMU 25, em simulações um caça que permanece em combate por mais tempo tem mais vantagem do que um projeto que voa rápido, o DMU 25 é 10% maior que o DMU 23 e 24, por ser maior dizem que ele perderia a capacidade de voo supercruseiro.
Observando a imagem do DMU 26 ele fica mais gordinho ainda com esses CFTs o que leva a crer que ficaria mais lento ainda, provavelmente nos DMU 27/28/29 eles devem ter trabalhado em como manter a capacidade de voo supercruzeiro com grande autonomia e capacidade de carga.

Japan backs out of plan to develop fighter jet on its own
By RYO AIBARA/ Staff Writer

March 5, 2018

Japan is moving to scrap plans to domestically develop a new advanced fighter jet due to staggering costs and anticipated engineering pitfalls.

The Defense Ministry initially had three possible alternatives for the fighter jet that would replace the F-2 fighter-attacker that will be gradually mothballed from around 2030.

But with China and Russia showing greater military assertiveness in the region, Defense Ministry officials faced the key task of replacing the F-2 with a fighter with more advanced capabilities.

The ministry decided its options were to fully develop the next-generation fighter jet domestically, develop it jointly with other nations, or extend the life of the F-2 through various modifications.

It initially leaned toward domestic development as it was deemed to "be important in maintaining Japan's fighter jet technology," according to a high-ranking defense official.

There were expectations that Mitsubishi Heavy Industries Ltd. would play a leading role in developing the fighter jet. This was before a subsidiary of Mitsubishi Heavy Industries ran into difficulties developing the Mitsubishi Regional Jet passenger aircraft for commercial production.

Finance Ministry officials eventually urged caution, citing the huge costs that domestic development would entail.

The government began to realize that domestic development of the next-generation fighter jet carried enormous risks.

Against that background, the Defense Ministry will not seek funding for domestic development of a next-generation fighter jet when requests are compiled this summer for the fiscal 2019 budget, sources said.

Tokyo is expected to sound out Washington as early as this week on the prospects of joint development of the next-generation fighter jet.

A decision on how to proceed will likely be formally made between fiscal 2019 and fiscal 2023 as that is the period covered by the Mid-Term Defense Program that will be put together before the end of the year.

It is still possible that Japan will place additional orders with the United States for the advanced stealth F-35A fighter jet manufactured by Lockheed Martin Corp. as the replacement for the F-2.

The government has already decided to purchase 42 stealth fighters to replace the F-4.

In light of pressure being applied by the Trump administration on allies to "Buy American," government officials may also decide to acquire the F-35A as the successor aircraft for the F-2.

The ASDF now has around 200 F-15 fighter jets, 50 F-4s and 90 F-2s. One F-35A fighter jet has been delivered.

The F-2 was jointly developed with the United States and deployed in fiscal 2000.

No dia seguinte o MD questionado sobre o assunto desmentiu tudo o que o jornal Asahi publicou, não foi tomado nenhuma decisão, no momento esta se recolhendo todas as informações para se apresentar o novo plano de defesa de 5 anos.

O jornal Asahi acho que e o segundo maior em circulação no Japão são anti qualquer coisa sobre assunto militar, se a fonte for Yomiuri da para confiar porque eles não publicam nada sem ter uma fonte oficial.

http://www.sankei.com/politics/news/180 ... 12-n1.html

O governo japonês pediu RFI para algumas empresas para poder apresentar todos os dados e definir o que fazer no próximo plano de defesa.

Acontece que eles tem que substituir 100 unidades dos primeiros lotes do F-15 urgente ate 2020, o programa de substituir os F-2 por F-3 e para 2030 por motivos obscuros $$$ se mistura o assunto diferente tentando encerrar o desenvolvimento do F-3.

Lockheed Martin to Propose 5th Gen F-22/F-35 Hybrid to Japan.



By Tom Demerly

New Proposed Stealth Hybrid Fighter to Expand Japanese Fighter Capability. Re-opening the F-22 Production Line might be an option too.
Late Friday, April 20, Reuters journalists Tim Kelly and Nobuhiro Kubo reported that Lockheed Martin will propose a new 5th generation low-observable (stealth) combat aircraft to Japan. According to Kelly and Kubo’s article, the two sources who provided the information to Reuters have direct knowledge of the upcoming proposal.

According to the sources with direct knowledge of the program quoted in the April 20 Reuters story, “Lockheed has discussed the idea with Japanese defense ministry officials and will make a formal proposal in response to a Japanese request for information (RFI) after it receives permission from the U.S. government to offer the sensitive military technology.”

Reuters quoted one of the two unnamed sources as telling them, “The proposed aircraft would combine the F-22 and F-35 and could be superior to both of them.”

The F-22 Raptor is only used by the United States Air Force and is not exported because some of its capabilities remain a national security asset. The F-35 Joint Strike Fighter was originally conceived as an export project to provide cost sharing and capability commonality between partner nations as a force multiplier.

The new Japanese aircraft to be proposed by Lockheed Martin will be an air superiority aircraft with a similar role to the F-22 Raptor.

The Japanese rolled out their first domestically built F-35A Joint Strike Fighter from Mitsubishi Heavy Industries Komaki South F-35 Final Assembly and Check Out (FACO) facility on June 5, 2017. Lockheed Martin built four of the first Japanese F-35s in the U.S. and delivered them to Japan. The remaining 38 of 42 total F-35As Japan has planned will be built at the Mitsubishi Heavy Industries Komaki South facility. Mitsubishi was the builder of the famous A6M Zero fighter used in WWII.

The Reuters report about the new Lockheed Martin proposal is set alongside the existing Japanese Mitsubishi X-2 Shinshin design originally designated the ATD-X for “Advanced Technology Demonstrator – X”. This aircraft bears a strong resemblance to the Lockheed Martin F-22 Raptor, using the same basic overall configuration. The ATD-X/X-2 Shinshin is a two-seat experimental aircraft whereas the F-22 and F-35 are only single seat aircraft. Only one X-2 Shinshin has been produced by Japan as a technology testbed. It first flew on April 22, 2016.

The reports of the new upcoming proposal from Lockheed Martin could suggest that Japan is considering abandoning its own indigenous fifth generation air superiority development program in favor of a design from another country. One stipulation reported by the source who spoke to Reuters was that any new proposed aircraft from outside Japan must have Japanese engines, radar and other components. This suggests that an additional, new vendor like Lockheed Martin may be primarily an airframe supplier.

The Reuters report did quote the Japanese Ministry of Defense as saying, “We are considering domestic development, joint development and the possibility of improving existing aircraft performance, but we have not yet come to any decision.”

There are a number of motives for Japan to consider a ground-up aircraft development for its own Gen 5+ aircraft. Perhaps the most compelling reason to consider a new direction are the lessons learned from the massive development processes for both the U.S. F-22 Raptor and the F-35 Lighting II Joint Strike Fighter.

Both the F-22 and F-35 programs were expensive and groundbreaking in terms of leading the Gen 5 integration of combat aircraft into an air force. The attendant costs of those programs can be amortized and benefitted from in new development aircraft. The implication is they could be both better and cheaper.

Another reason for the shift in interest to a new Gen5+ direction for Japan’s next air superiority fighter is China. A March 15, 2018 article by Kyle Mizokami in Popular Mechanics quoted Chinese aircraft developer Yang Wei, deputy director of advanced of science and technology at Aviation Industry Corp of China and member of the Chinese Academy of Sciences, as saying, “We are not complacent about what we have achieved. We will develop the J-20 into a large family and keep strengthening its information-processing and intelligent capacities. At the same time, we will think about our next-generation combat plane to meet the nation’s future requirements.”

China has also been active in expanding its export market for tactical aircraft, although advanced aircraft like the J-20s are likely to remain exclusively Chinese. Japan may look to co-develop a new aircraft that could possibly have limited export appeal in the region, provided the buy-in were lower than F-35.

The costs of re-opening the F-22 production line, or even some version of it, have been generally regarded as prohibitive. However, Tyler Rogoway at The War Zone has long been advocating a sale of Raptors to Japan. In the 2016 story “Just Allow The F-22 To Be Exported To Japan Already“. Here’s a short excerpt from Tyler’s latest article on this subject (but I strongly recommend reading the whole story):

“Although Japan has put forward notional Raptor-like designs, what they could also be talking about here is merging the higher kinematic performance and low-observability of the F-22 with the F-35’s smarter attributes—including updated avionics, mission computers, and sensors—as well as new lower-maintenance skin coatings.

[…]

That cost [to put an updated F-22 back into production] may be too high for the USAF to stomach, but for Japan, it’s highly unlikely they will be able to field something superior to an updated F-22 for anywhere near less. It’s also likely that once the U.S.-specific politics of putting the Raptor back into production are removed from the equation, the cost of doing so would drop.

But if Japan is willing to buy an updated Raptor instead of developing a near identical but still unique design, clearly doing so would present a mutually beneficial opportunity. If the U.S. would become a minority stakeholder in an F-22 production line restart of sorts, with the intent on buying a number of airframes to bolster the USAF’s undersized and cherished F-22 fleet, then the opportunity could work out for both parties.

[…]

We will watch how this story develops closely, but if the Pentagon was smart, they would embrace an upgraded F-22 restart with Japan, and if Tokyo is willing to foot the majority of the bill for doing so, the USAF would be nuts not to take advantage of it. “

Indeed, this cost-sharing strategy between the U.S. and Japan would be a significant win-win, especially with the U.S. need for more F-22s. Let’s see what happens.

Resumindo ficou pronto a turbina XF9-1 de 15t de empuxo, foi entregue dia 29 ao ministério de defesa para iniciar os testes.
tem 4.8m de comprimento, 1m de largura, 15t com pôs combustão e 11t sem pôs combustão, foi projetada para sustentar 1800°C no compressor, o desenvolvimento se iniciou em 2010.

[Juniorbombeiro]

Não leio japonês, mas certamente essa temperatura deve ser na turbina e não no compressor. Aliás uma turbina que trabalha a essa temperatura não deixa de ser um grande feito de engenharia.
Para efeitos de comparação, o atual Benchmark da indústria de turbinas é a PW F-135 (desconheço as russas), com alegados 1982° C de temperatura máxima na entrada da turbina. Isso não quer dizer que vá operar sempre nessa temperatura. Se especula que a maioria das turbinas militares de vanguarda não operam a mais de 1700° C, os japas estão de parabéns.
