Avia Press Associates 2021 Spring 2021 78 Page 67 IT DOESN’T SEEM LIKE 50 YEARS have passed since Agusta carried out the first flight of the shapely A109 helicopter at their Cascina Costa factory, but we remember at the time thinking how well the Italian flair for design had surely given the company a big head start over its competitors in the light twin market. The 2.4 tonne eight seater, with its four-blade articulated rotor, semi-rigid two-blade tail rotor and retractable landing gear certainly looked the part, but mechanical challenges meant it took a little over four years from the first flight on 4 August 1971 to certification and entry into service. Since then the basic model has been considerably improved and upgraded, with the current 3 tonne class AW109E Power, AW109S Grand, and GrandNew typifying the success of the aircraft. In fact over 1,600 aircraft have been sold over those 50 years, whilst the company itself found a firm foothold in Philadelphia where it established its first A109 support centre as North American sales lifted off. Whilst the lengthy gestation gave rivals, including the Bell 222, a chance to catch up, nevertheless the A109 was the first of a new generation and as such has a guaranteed place in history. * The US Army next generation FARA (Future Attack Reconnaissance Aircraft) and FLRAA (Future Long Range Assault Aircraft) competitions are beginning to look distinctly wobbly and very expensive to the outside observer. The Army’s project manager has already said that the original performance requirements for the future rotorcraft “are not compatible” with the law of physics and that the schedule previously set for the competitive fly off in the FARA programme is not attainable either. FARA sees Sikorsky with its advanced compound Raider X coaxial rotor design going head-to-head with the much simpler Bell 360 Invictus, which now uses the company’s Model 525 rotor and transmission system after abandoning various shrouded tail rotor options. Whilst the latter offers far less technical risk, it doesn’t meet the performance levels promised by the Raider X, provided of course that reliability and field maintenance issues are not an issue for the latter. These same features are in play with the FLRAA, where Sikorsky Boeing remain very coy regarding progress with their larger compound coaxial offering, the SB-1 Defiant X. In this competition the partners are up against a Bell tiltrotor, developed from the V-280 Valor which has already completed its full demonstration programme and has now been retired. With Bell now looking again at folded proprotors on tiltrotors to further increase range and performance, one wonders where FLRAA will eventually go. Page 68 DRF Luftrettung upgrade H145s DRF Luftrettung has begun upgrading its fleet of Airbus H145 helicopters from the four-blade to a five-blade configuration, in a three year programme that also involved modifications to the transmission, exchanging batteries and software updates. Previously the company took delivery last December of a brand new five-bladed H145 from Airbus, which entered operational service in the Stuttgart region in March and provided further confidence for the retrofit programme. This first retrofit was carried out the trials prove successful and demonstrate Above: This Airbus H145 of ADAC Luftrettung was demonstrated at the beginning of June, using in cooperation with Airbus at their the viability of the UAV operations, the partners believe that both the urban and sustainable aviation fuel in its Safran Arriel 2E Donauwörth factory, providing initial engines.

  • Bell 505 Jet Ranger X
    PILOT REPORT Bell 505 Jet Ranger X 505 single improves on the 206’s legacy by Alexa Rexroth In mid-January, 20-degree temperatures in Texas coupled with substantial wind gusts and the threat of snow almost placed me directly in the right seat of a Bell 505 simulator instead of the real helicopter. But with conditions improving upon my arrival at Bell’s Fort Worth, Texas factory, it was announced, with great relief to me, that the flight in Bell’s 505 Jet Ranger X would take place as planned. www.ainonline.com/order-reprints Championed by Bell as the most advanced light single in the market, the 505 Jet Ranger X offers first-in-class features including a dual-channel Fadec and fully integrated Garmin G1000H flight deck. Designed to echo the storied career of the B206-series JetRanger while advancing its class’s legacy into the future, the 505 is suitable for utility, corporate, parapub- lic, and training mission profiles. Bell is working on utility options for the 505 and expects to certify a cargo hook later this year. With commercial deliveries continuing to climb along with letters of intent, the heli- copter is retaining its welcomed entrance into the market. © 2018 AIN Publications. All rights reserved.

  • ERF2018-Active Vibration Control for the Kazan Ansat Submittal02
    Paper #133 ACTIVE VIBRATION CONTROL FOR THE KAZAN ANSAT Bastian KINDEREIT, [email protected], LORD Corporation (France) Paul BACHMEYER, [email protected], LORD Corporation (France) Alexandre BONDOUX, [email protected], LORD Corporation (France) Doug SWANSON, [email protected], LORD Corporation (USA) Anton BUSHUEV, [email protected], Kazan Helicopters (Russia) Abstract This paper presents a high-level overview of the implementation and the results of LORD’s OMNI Active Vibration Control System (AVCS) on Russian Helicopter’s Ansat helicopter platform as well as a brief description of principles of the technology. The AVCS is designed so that it can be easily adapted to both existing production aircraft and new aircraft development to actively reduce in-flight vibration levels. Vibration reduction allows for increased crew comfort, reduced equipment fatigue and in certain cases even an increased flight envelope at minimal installation weight versus performance compared to other vibration reduction technologies. The technology is architected with a high degree of modularity to allow it to be adapted to a wide variety of aircraft and customer use-cases. The primary goal on the Ansat was to configure the AVCS to reduce vibration levels at the VIP seats in the aft cabin although cockpit vibration levels were also to be considered. LORD engineers worked with the Russian Helicopters team at the Kazan, Russia facility to integrate and tune the system through simulation and flight test, which resulted in reductions in vibration levels at the VIP seats of up to 84% depending on flight condition. Ultimately, these efforts resulted in two production configurations, which first appeared on a production Ansat in February 2018, making it the first Russian helicopter with LORD’s Active Vibration Control technology.

We think that the most correct way will be to divide it, at first by subordination and then by purpose. There were three branches which had aircraft factories, namely: MAP Ministerstvo Aviatsionnoi Promyshlennosti (Ministry of Aviation Industry) MGA Ministerstvo Grazhdanskoi Aviatsii (Ministry of Civil Aviation) - about the same as Aeroflot MO Ministerstvo Oborony (Ministry of Defence) MAP - Ministerstvo Aviatsionnoi Promyshlennosti The MAP was responsible for the design and production of both civil In the mid-1970s and 80s, when secrecy (at least in its most foolish and military planes, helicopters, aviation weapons, equipment etc. Its examples) faded, most factories were renamed again as "[city's] structure includes two sorts of aircraft factories: usually in use as acronym only - [first letter[s] of city's name] APO", where APO means "Aviatsionnoye Proizvodstvennoye Obyedineniye" Serinyye zavody (those usually associated with the word "aviazavod") (aircraft production association - association means that this enterprise - intended for mass production of types which are selected for that.
