Embraer still bets on the STOUT hybrid plane


Manufacturer, however, said it needed a new partner after the Brazilian Air Force left the project

The STOUT project, for an aircraft with hybrid propulsion, remains on Embraer's agenda, despite the withdrawal of the Brazilian Air Force (FAB), which would be a partner in the development of the utility model.

In a meeting with journalists last week, Jackson Schneider, executive president of Embraer Defense & Security, said that the manufacturer remains committed to the project. "We intend to [resume the project] as the conditions allow, even with different partners," the head of Embraer's military products division told Flight Global.

In May, the Air Force Commander, Lieutenant Brigadier Carlos de Almeida Baptista Junior, confirmed the departure from the program due to budget constraints. The STOUT was proposed to replace the older C-95 Bandeirante turboprops, in service with the force for nearly five decades, in addition to the C-97 Brasilia.

According to the outlet, Schneider said that Embraer's initial studies of the hybrid plane proved to be valuable. However, the executive emphasized that the manufacturer needs "different potential partners" to take the project forward, which would eliminate dependence on the Brazilian Air Force.

Versatile and sustainable aircraft
Jointly announced by FAB and Embraer in 2020, the STOUT project was the reason for an agreement that would give rise to an advanced aircraft, capable of operating with a more efficient propulsion system and low emission of polluting gases.

Computer-generated images presented by Baptista Junior's predecessor, Brigadier Antonio Carlos Moretti Bermudez, in December 2020, revealed an aircraft with a configuration similar to the reduced-scale KC-390 Millennium, but equipped with four engines, two turboprops and two other engines. electrical, at the tips of the wings.

Also according to Bermudez, the STOUT, an acronym for "Short Take Off Utility Transport", would be able to operate on short and semi-prepared runways, would carry three tons of payload or 30 soldiers and would fly for up to 2,425 km without replenishment. The project was also supposed to have a civilian variant.

Gaat het om hetzelfde toestel of is dit weer een ander type toestel waarmee Embraer  bezig is?

Heb de indruk dat het om een ander type toestel van Embraer gaat.
A fighter without a gun . . . is like an airplane without a wing.

EMBRAER ZET ONTWIKKELING VAN NIEUW TURBOPROPTOESTEL DOOR



SAO JOSE DOS CAMPOS - Embraer wil de plannen voor de ontwikkeling van een geheel nieuw turboproptoestel doorzetten. De Brazilianen verwachten volgend jaar het programma te lanceren, en hopen de eerste toestellen in 2027 of -28 te leveren, zegt topman Arjan Meijer.

Het is al lang geleden dat er in de westerse wereld nog een turboproptoestel in het regionale segment ontwikkeld is. De populairste turboprops, de ATR's en de Dash 8's, stammen in de basis al uit de jaren tachtig van de vorige eeuw, al zijn ze sindsdien wel steeds verbeterd.

Volgens Meijer, de Nederlander die de commerciële vliegtuigendivisie van Embraer leidt, zal de nieuwe turboprop een veel betere passagierservaring bieden. Het toestel "gaat zich echt onderscheiden van de huidige producten in de markt", zo zei hij woensdag tijdens een online persbijeenkomst.

Een turboprop is volgens Meijer het ideale toestel om nieuwe, duurzamere aandrijftechnieken te introduceren. Hij noemt verder niet welke, maar het zou dan bijvoorbeeld kunnen gaan om hybridemotoren, die deels op accu's en deels op (bio)kerosine functioneren.

De Embraer-turboprop krijgt in de basis dezelfde romp als de Embraer E2-jets, maar dan korter en natuurlijk wel met de nodige aanpassingen. Het vliegtuig heeft naar verwachting een capaciteit van ergens tussen de 80 en 100 passagiers. Verder is er nog vrij weinig over bekend.

KLM-topman Elbers heeft overigens al aangegeven geen interesse te hebben. Hij richt zich op grotere toestellen, mede vanwege de beperkte ruimte op Schiphol.

Nee

Dit toestel is heel erg klein, qua capaciteit vergelijkbaar met een CASA C-212 Aviocar (25 para's). Als je dan een civiele kist verbouwd tot marpat kies dan voor de Dash-8 die heeft tenminste nog de potentie om er ook echt iets mee te kunnen.

ALS we ooit zo iets zouden aanschaffen is het eerder iets voor SOF support dan voor iets anders.

Het vervangt dus de Embraer EMB 110 Bandeirante en Embraer EMB 120 Brasilia.

Het zit inderdaad in de militaire klasse van de CASA C-212 Aviocar, Antonov An-28, Short Skyvan, IAI Arava, Short C-23 Sherpa

De civiele versie valt in de klasse van de Havilland Canada DHC-6 Twin Otter, Dornier 228, GAF Nomad, Saab 340, ATR 42, Aircraft Industries L 410 NG

Embraer Defense Analyzes New UAS, Military Transport Projects


The Brazilian Air Force and Embraer are analyzing a concept for a Short Take-Off Utility Transport.

Unmanned aircraft systems and a hybrid-electric military transport could be added this year to Embraer's bulging portfolio of defense platforms, the company's chief executive said in an exclusive interview.

Eight months since planned joint ventures with Boeing on Embraer's commercial business and the KC-390 military transport fell apart in acrimony, the Brazilian manufacturer remains focused on broadening its portfolio of defense products, which include a partnership with Saab to design a two-seat version of the Gripen JAS 39, as well as developing airborne-early-warning-and-control aircraft, a light-attack fighter and small satellites.

Embraer may announce new family of UAS

Brazilian air force unveils STOUT concept

The first project that could be revealed later this year is a revived program to develop a large UAS for the Brazilian military. It would follow the Harpia joint venture formed in 2011 with Elbit Systems subsidiary AEL Sistemas and Avibras, which halted development five years later amid government spending constraints.

"We believe that this market—we have to be there," says Jackson Schneider, CEO of Embraer Defense and Security. "Perhaps we will be able to announce something in 10 months."

The former Harpia joint venture provided few details about the UAS program, except to release a concept image of a single-engine, twin-boom design. The medium-altitude, long-endurance aircraft was aimed at providing surveillance of Brazil's remote western borders with a beyond-line-of-sight control link.

Any future program may avoid focusing on a single-platform solution for a new UAS and focusing only on the defense market for applications, Schneider says.

"We are analyzing a full family," Schneider says. "Defense is already a market where this product is more than a concept; it's required. And the other markets perhaps will need more time to trust this technology."

Applying military-funded projects to the commercial market—and vice versa—has been Embraer's modus operandi since its founding 52 years ago. The Brazilian Air Force established Embraer to market a military transport called the C-95 Bandeirante to airlines as the EMB 110. The follow-on EMB 120 was designed for the commercial market but also sold to the air force as the C-97 transport.

As the C-95 and C-97 fleets approach retirement, a new concept has emerged to replace them. The Short Take-Off Utility Transport (STOUT) concept was unveiled in November by Gen. Antonio Moretti Bermudez, the air force commander. Embraer, and the air force signed a memorandum of understanding in December 2019 to begin research for such an aircraft.

The concept revealed in November shows an aircraft with a T-tail and a fuselage roughly comparable in length to the 65-ft. 7-in. (20-m) EMB 120, although wider. The STOUT aircraft also would use a hybrid-electric propulsion system with four propulsors fed by two gas generators on the inboard wing stations. The air force requirements include an aircraft that can operate on the unpaved landing strips of Brazil's Amazon region while carrying up to 6,600 lb. (3,000 kg.) of cargo.

So far, the air force has supported only research and concept studies, but a funded development program could be a natural follow-on to completing deliveries of all 36 F-39E/F Gripens and 28 KC-390s to Brazil, which are scheduled in 2026 and 2027, respectively.

At this point, Embraer is seeking to reapply the familiar development model: a military transport program with dual-use applications in the commercial market. The same design requirement to operate from unpaved landing strips in the Amazon may be relevant in certain commercial markets such as countries comprising many islands, Schneider says.

Its hybrid-electric propulsion system also may provide a more environmentally friendly alternative for inter-urban transports, he notes. "This is what we are analyzing," he says. 

If the UAS and STOUT projects move into production, Embraer would gain two new defense platforms in the second half of the decade.

At the moment, Embraer's defense production facility in Gaviao Peixoto, Brazil, is assembling the first locally built Saab Gripen F-39E for rollout later this year as well as KC-390s for Brazil, Portugal and Hungary and A-29 Super Tucano light-attack aircraft.

Only a year ago, Embraer planned to join forces with Boeing to establish a joint venture to market the KC-390 in international markets, particularly the U.S. When Boeing severed the commercial and KC-390 joint ventures in April 2020, the U.S. company noted that a 2016 agreement to market the KC-390 outside a joint venture remained in effect. Both companies are still discussing the future of the KC-390 marketing relationship, Schneider says, but he adds: "I cannot elaborate more on it."

Embraer shows images of new hybrid-electric short take-off transport

Brazil's air force previewed renderings of a proposed Embraer hybrid-electric short take-off military and commercial transport aircraft for the first time on 13 November in a video at a defence seminar.

Embraer and the Brazilian air force signed a memorandum of understanding in December 2019 to develop a new light military transport aircraft. Embraer acknowledges that the hybrid-electric renderings are the product of its memorandum of understanding, but declines to provide additional information beyond the video.


Embraer STOUT military variant

The Short Take Off Utility Transport (STOUT) is intended to replace the Brazilian air force's Embraer EMB-110 Bandeirante (designated C-95A) and EMB-120 Brasilia (designated C-97), according to recordings of the video presentation posted online by several Brazilian media outlets on 13 November. The STOUT would have two turboprop engines that also turn generators to provide power for electric-driven propellers on the aircraft's wingtips.

The continued pursuit of the STOUT project comes as Embraer's commercial airliner manufacturing division has been hard-hit by the coronavirus downturn, as well as Boeing's decision in April to walk away from a deal to acquire the company. Boeing also cancelled a planned joint venture agreement with Embraer to promote its C-390 Millennium medium-lift transport outside of Brazil.

Brazil has 64 examples of the twin-turboprop EMB-110 light transport in service, with an average age of 38.3 years, according to Cirium fleets data. The country's military has 19 examples of the EMB-120, a twin-turboprop commuter aircraft, with an average age of 26.5 years.

The STOUT is designed to have roughly the same height, width and length as the EMB-110 and EMB-120, according to the Brazilian air force video presentation.

The aircraft is intended for "serving remote locations with short, narrow and unpaved runways", says Brazilian aviation publication Poder Aero. It must be capable of "transporting cargo and personnel in jungle areas, reaching major airports in South America, launching parachutists, extracting pallets and transportation of the sick".

The transport must also be able to take off from a 1,200m (3,940ft) runway and operate in an "Amazonian environment".


Embraer STOUT civilian variant

The hybrid-electric transport is to have a 1,310nm (2,420km) range and maximum payload of 3 tonnes. It would come with a rear cargo ramp for loading and unloading cargo and passengers, says the promotional video. The EMB-110 and EMB-120 lack a rear cargo ramp. The STOUT aircraft would be capable of carrying 24 paratroopers or 30 soldiers.

Embraer and the Brazilian government intend to use the country's need for a new military transport to jumpstart hybrid-electric aircraft development, a new form of aircraft that many believe is promising for regional or commuter commercial passenger service due to possibly lower fuel and maintenance costs, as well as a lighter environmental impact. The company brands the aircraft as "dual-use".
