Boeing nearing flight tests for all-new AH-64 engine
By Stephen Trimble
Boeing has outlined plans to integrate and test the power upgrades at the heart of the Block III upgrade programme for the US Army AH-64D Apache Longbow.
Manned-unmanned teaming and avionics improvements have been the focus over the past year of flight tests for the Block III system, the first major Apache fleet upgrade since the Longbow version was introduced about 20 years ago.
But the Block III programme is also aimed at improving the engine's thrust by 20%. The new General Electric 701D will increase its thrust rating from 2,828shp to 3,400shp.
Il y en a qui doivent regretter d'avoir critiqué l'Apache, et les clients qui l'ont acquis ! Il ne sera jamais rattrapé !
Meanwhile, an all-new drive system, including the operational debut of a gearbox with split-torque face gear, will enable the currently limited transmission to handle the higher power levels.
Boeing is now validating in ground tests that the new face gear technology is meshing most efficiently and making refinements, said Scott Rudy, Boeing's Apache programme manager.
Intéressant !
The face gear checks will be quickly followed by completing bench tests on the new drive system by end-May, Rudy said. The new transmission will be tested on a ground test vehicle in July, he said.
Devinez quel facteur 'in theatre" assez récents qui a accéléré ce genre de travail !
Finally, the new power and drive systems will be installed on a structures vehicle that arrives in the flight test fleet in August, Rudy said.
Ici, Boeing & GE avancent vite et bien !
The army will conduct a limited user test (LUT) using two Block III test vehicles starting in November, but neither will include the power upgrades. Instead the LUT is focused on evaluating the manned-unmanned teaming, including full control of an unmanned aircraft and sensor from the Apache cockpit.
Coopération actiuve et "pro-active" avec le militaire ! Admirable ! Approche très orientée "opérations en théâtre" !
Immediately following the LUT, the army will begin testing Block III test vehicles that have the full package of engine and avionics improvements, Rudy said.
The Block III programme then has two years to complete development before launching its graduation exercise - the initial operational test and evaluation (IOT&E) - in the first quarter of Fiscal 2012.
Travaux visiblement bien coordonnés. Et cette efficacité de coordination va se poursuivre !
The US Congress, meanwhile, is steadily expanding the programme.
A noter !
The army's initial requirement for Block III Apaches ranges between 224 to 236, but the Congress is adding up to 52 wartime replacements through FY11 and convert four Army National Guard battalions from AH-64As to the D-model.
Boeing also believes the army has a long-term requirement to acquire nearly 400 more AH-64Ds from 2017 to 2040, raising the overall fleet to about 800 aircraft over that period.
Avec une telle 'base installée USA', Boeing / GE pourront faire des offres 'agressives' à l'exportation !

Egypt to Buy 12 AH-64D APACHE Longbow Helicopters within FMS Programme

Boeing Remanufactures AH-64A Apaches to AH-64D Block II

http://www.defenseindustrydaily.com/115b-contract-to-remanufacture-129-apaches-to-ah64d-longbow-configuration-02972/#more-2972

08:38 GMT, May 28, 2009 WASHINGTON | On May 22, the Defense Security Cooperation Agency (DSCA) notified the US Congress of a possible Foreign Military Sale to the Government of Egypt of 12 AH-64D Block II APACHE Longbow Helicopters and associated equipment, parts, training and support for an estimated cost of $820 million.

The Government of Egypt has requested a possible sale of 12 helicopter of this type
as well as 27 T700-GE-701D Engines, 36 Modernized Targeting Acquisition and
Designation Systems/Pilot Night Vision Sensors.

The helicopters will be additionally armoured with M299 HELLFIRE Longbow Missile Launchers.
the aircraft receives also additional AN/ALQ-144(V)3 Infrared Jammers, and 39B(V)2
Radar Signal Detecting Sets.
Also included: composite horizontal stabilizers, Integrated Helmet and Display Sight Systems, repair and return, transportation, depot maintenance, spare and repair parts, support equipment, publications and technical documentation, U.S. Government and contractor technical support, and other related elements of program support. The estimated cost is $820 million.

A DSCA official said in an statement that this proposed sale will contribute to the foreign policy and national security of the United States by helping to improve the security of a friendly country which has been and continues to be an important force for political stability and economic progress in the Middle East.

Egypt will use the AH-64D for its national security and protecting its borders. The aircraft will provide the Egyptian military more advanced targeting and engagement capabilities. The proposed sale will provide for the defense of vital installations and will provide close air support for the military ground forces. Egypt will have no difficulty absorbing
these helicopters into its armed forces.
The proposed sale of this equipment and support will not alter the basic military balance in the region.

The prime contractors will be The Boeing Company in Mesa, Arizona, and St. Louis, Missouri, General Electric Company of Lynn, Massachusetts, and Lockheed Martin Missiles and Fire Control in Orlando, Florida. There are no known offset agreements proposed in connection with this potential sale.
Implementation of this proposed sale requires the assignment of one U.S. Government representative to Egypt for a period of six years to provide intensive coordination, monitoring, and technical assistance to assure a smooth transition of the helicopters in country. Additionally, six contractor representatives will be in Egypt conducting duties as Contractor Field Service Representatives for a period of five years and with a possible five-year extension.
There will be no adverse impact on U.S. defense readiness as a result of this proposed sale.

Boeing AH-64D Apache Block III Successfully Demonstrates Level IV UAS Connectivity

http://www.defpro.com/news/details/8267/

13:32 GMT, June 24, 2009 MESA, Ariz. | Boeing [NYSE: BA] today announced that the AH-64D Apache Block III prototype helicopter successfully demonstrated Level IV unmanned aircraft system (UAS) connectivity on June 8 during a flight test over the Arizona desert.

Level IV UAS connectivity is one of the key technology enhancements being developed for the U.S. Army's Apache Block III attack helicopter program. At this level, the Apache crew is able to fully control the
navigation of an assigned UAS. The capability provides enhanced situational awareness and over-the-horizon, beyond line-of-sight reconnaissance, improving survivability for the crew and the aircraft. (Level I connectivity is receipt and transmission of secondary imagery or data, Level II is receipt of imagery or data directly from the UAS and Level III is control of the UAS payload.)

During the test, the Apache proved capable of controlling the UAS via a Tactical Common Data Link connection. The Apache crew received real-time video from the UAS, controlled the UAS's three navigation-loiter patterns -- orbit, racetrack and figure eight -- and altered the UAS's airspeed and altitude.

For this demonstration, Boeing, under Army direction, used a Boeing AH-6 helicopter as a surrogate for Sky Warrior, the Extended Range/Multi-Purpose UAS that is not yet available.

"Integration of UAS control is a key technology for the Apache Block III helicopter as we prepare
for the limited user test scheduled for later this year," said Scott Rudy,
Boeing Apache Block III program manager. "The members of Team Apache -- the U.S. Army, Boeing and our industry partners -- are proud to have achieved this critical capability."

Merci Paul
Modernisation des cellules actuelles
Etonnant de parler de T-700-GE-701D alors que les WAH64 sont en Turbomeca
Cette version fait 2000shp au max ( http://www.geaviation.com/engines/docs/military/datasheet-T700-701D.pdf ) vs 2100shp pour les RTM322 sélectionnés ( http://www.turbomeca.com/sites/turbomeca/files/rtm322_-_sale_brochure_1.pdf )

https://www.avionslegendaires.net/2019/08/actu/le-maroc-souhaite-remplacer-ses-gazelle-par-des-apache/

C’est un contrat d’un peu plus d’un milliard d’euros que le gouvernement marocain se préparerait à signer avec la branche voilure tournante du géant américain Boeing.

Les Forces Royales Air, ou si vous préférez l’aviation marocaine, sont actuellement en pourparlers avec l’industriel autour de la fourniture de vingt-quatre AH-64E Guardian, l’ultime évolution du célèbre Apache.
Des hélicoptères de combat qui pourraient à l’horizon 2022-2024 remplacer les Aérospatiale SA.342 Gazelle, des machines en service depuis la fin des années 1970. Il est à signaler qu’à aucun moment le royaume chérifien n’est passé par un appel d’offres internationales.

Les militaires marocains ont de toutes manières toujours agi de la sorte. Quand un matériel de défense leur plait, s’il est dans leurs moyens financiers ils vont essayer de l’acheter. La règle d’or sur les appels d’offre n’a jamais vraiment été leur dada. On se souvient de l’achat des Alpha Jet E qui avait en son temps soulevé quelques indignations chez les avionneurs concurrents du consortium franco-allemand conçu par Dassault-Breguet et Dornier.
Mais dans le cas présent il ne devrait pas forcément y avoir de remous, l’hélicoptère en question n’a pas vraiment de concurrence sur le marché marocain.

Car ce sont donc vingt-quatre Apache qui devraient très prochainement être achetés par le ministère marocain de la défense. Pour être exact ces machines seront des Boeing AH-64E Guardian, la version la plus récente de cet aéronef issu de la guerre froide.

Si le Maroc a un temps envisagé l’AW.129 Mangusta proposé par le groupe européen Leonardo il s’est rapidement ravisé pour commander l’appareil américain. L’Airbus Helicopters Tiger n’a jamais été dans la compétition, car jugé trop onéreux.

Je serais étonné que le Maroc achète du matériel militaire non-américain. Dans ce cas précis, ce type d'appareil répond-il vraiment à un besoin militaire ? Un hélico plus léger ne ferait-il pas l'affaire ?
