Autogyro

På besøk i autogyroens hjemland Spania i forrige uke, observerte jeg en slik maskin over Las Palmas. Her er vanligvis lite å se til flytrafikken fra den travle internasjonale flyplassen lenger sør på øya, men av og til kommer det over en Puma fra Armada eller et SAR helikopter. En uvanlig lyd førte blikket mitt til himmels og jeg dro frem kameraet og tok dette bildet:


Senere samme dag var det en SAR/amulanse AW139 som jobbet et stykke fra kysten. Denne er en del av den sivile redningstjenesten som Helikopter Service startet opp tidlig på 90-tallet. Først i La Coruna, og senere over hele landet, også på Kanariøyene. Her opererer fremdeles en tidligere HS S-61N, vanligvis fra Lanzarote. Her  et dårlig bilde av AW139 på jobb vest av Las Canteras stranden:


Av annen trafikk så jeg en Herc. Den sto senere på flyplassen og var fra USAF. Der var også en A295 som tilhørte Armada, samt noen CASA maskiner.

AW169 - ULYKKEN I LEICESTER
Havarikommisjonen nærmer seg svaret på hvorfor AW169 styrtet i Leicester
Presenterer funnene som avslører teknisk feil på helikoptertypen som er svært viktig for Norge.
      7. DES. 2018 - 15:1
Da den katastrofale feilen oppsto, var det lite fra eller til flygeren kunne gjøre for å unngå havari. 
Det kommer tydelig fram i en ny foreløpig rapport fra den britiske flyhavarikommisjonen AAIB (Air Accidents Investigation Branch).

To foreløpige rapporter
Alle fem om bord omkom da et AW169 styrtet ved Leicester stadion i England 27. oktober. Videoopptak fra ulykken viser at flygeren hadde mistet kontrollen over halerotoren. Nå presenterer havarikommisjonen tekniske funn som viser at dette skyldtes teknisk svikt.
Den første foreløpige rapporten kom 14. november og sa ikke noe om årsaksforhold. Det var en kortfattet framstilling av hendelsesforløpet og presentasjon av data hentet fra ferdsskriveren.
Den andre foreløpige rapporten, som ble publisert 6. desember, er mer fyldig der den tar for seg de tekniske undersøkelsene. Halerotorsystemet ble gransket på havaristedet, og det ble påvist at forbindelsen mellom halerotoren og styrekontrollene framme i cockpit var brutt.
«Yaw»-pedalene er forbundet med halerotoren med en fleksibel kabel som er koblet til et styrestag i enden via en såkalt «bellcrank». Den andre enden av staget er koblet til det som kalles «Tail Rotor servo-actuator feedback lever» og som styrer halerotoren.

Styrestaget går på innsiden av en roterende aksling som overfører kraft. De tekniske funnene er forenlig med at også den innerste akslingen har rotert. Tilstrekkelig kraft og moment er påført mutteren i aktuatorenden av staget til at den er blitt friksjonssveiset fast i akslingen, mens saksesplinten er revet av.  
Da stagoverføringa feilet og gjorde feedback-mekanismen ubrukelig, hjalp det ikke å trykke ned pedalen, som ferdsskriverdata viser at flygeren gjorde. Halerotoren levde sitt eget liv og fortsatte å endre bladvinkel så langt det gikk an. Resultatet var en ukontrollerbar vridning mot høyre. 

Blant det som skal undersøkes videre er hva slags rolle i hendelseskjeden et lager («duplex bearing») har hatt. Det er gjennom CT-skanning observert skader på indre lagerbane, samt oppsamling av støv og metallpartikler, mens det var helt uten smøremiddel. 

Politiet og Kystverket
Det AAIB ennå ikke sier noe om, og som derfor fortsatt må holdes åpent, er for eksempel om dette skyldes en designfeil, produksjonsfeil/kvalitetsfeil eller vedlikeholdsfeil/monteringsfeil, eller kanskje en kombinasjon av flere ting.
– Den utløsende årsaken og det eksakte hendelsesforløpet undersøker vi fortsatt, og det er et prioritert arbeid, understreker havarikommisjonen.
Det er sendt ut flere hastekrav om inspeksjoner av halerotorkomponenter. Både gjennom flere «Service Bulletin» (SB) fra produsenten Leonardo Helicopters og «Emergency Airworthiness Directive» fra europeiske luftfartsmyndigheter (Easa). Den siste kom 30. november og krevde gjentatte inspeksjoner av låsemutter og lager. 
Det finnes fortsatt bare litt over 60 slike helikoptre i drift verden rundt. Havariundersøkelsen følges tett blant flere her til lands:

Det er under tre måneder til Politiet etter planen motta sitt første av tre bestilte AW169.

Helikoptertypen har dessuten vært i drift i tre eksemplarer i halvannet år allerede hos Airlift, som bruker det som loshelikopter for Kystverket. Dette er en svært krevende operasjon.
Airlift fortalte til Teknisk Ukeblad i slutten av november at de fortløpende har fulgt opp direktivene fra luftfartsmyndighetene i tillegg til å foreta inspeksjoner på sine AW169-helikoptre etter eget initiativ. De har ikke funnet noe ureglementert.

Tidl. President George H.W. Bush hedres big time - AVweb

21-Hornet Flypast At Bush Interment
 
Russ Niles
 
 

Rather than a 21-gun salute, the Navy’s planned tribute to the late President George H.W. Bush could be called a 21-top-gun salute. The Navy is planning a 21-aircraft missing man formation for the interment ceremony of the former president at the George Bush Presidential Library and Museum in College Station, Texas, on Thursday. It’s the largest-ever missing man formation attempted by the Navy. Naval Air Station Oceana, Virginia, deployed a total of 30 F/A-18 Super Hornets for the mission and they arrived in Texas on Tuesday.
Bush was a torpedo bomber pilot in the Pacific Theatre in the Second World War and had to bail out of his aircraft when it was shot down in 1944. He was rescued by a submarine and rejoined his unit aboard USS San Jacinto and flew a total of 58 missions, earning the Distinguished Flying Cross. “In addition to being our president, he was also one of our brothers, flying combat missions off aircraft carriers during World War II,” said Rear Adm. Roy Kelley, commander of Naval Air Force Atlantic. “His service to our Navy and nation merits a tribute of this magnitude.” The lead aircraft has been painted with Bush's name under the pilot's seat and his late wife Barbara's name under the backseater's canopy.

Toulouse, 7 December 2018 – Dublin, Ireland headquartered aircraft lessor Avolon has firmed up an order for 75 A320neos and 25 A321neos. The agreement is the single largest order for Airbus aircraft ever placed by Avolon.

The agreement takes Avolon’s cumulative orders with Airbus to 284 aircraft (240 single-aisles and 44 wide-body aircraft) including the A321neo, the A330neo and the A350 XWB.

Dómhnal Slattery, Avolon CEO, commented: “Our order for 100 A320neo family aircraft builds on our leading industry position and reflects our ambition to become the global leader in the sector. We continue to see robust demand from our customers for the A320neo family globally. This is consistent with our own market research and global fleet forecast. This order affirms our belief in the medium-term market outlook and the strong growth prospects for our business and our shareholders.”

“This order underscores the market appetite for the efficiency, reliability and passenger appeal of our A320neo Family,” said Christian Scherer, Airbus Chief Commercial Officer. “The A320 Family of aircraft is a future-proof asset for investors and airlines alike. Avolon’s recent success is a testimony to its leadership’s dedication to our industry. Its commitment to Airbus reflects its profound market insights. I personally look forward to further extending this relationship as we go forward.”

The new order for 100 aircraft together with the 22 single-aisles and four wide-bodies already delivered, increases Avolon’s Airbus backlog to 258, the largest of any lessor.

Featuring the widest single-aisle cabin in the sky, the efficient A320neo Family incorporates the very latest technologies including new generation engines and Sharklets, which together deliver more than 15 percent fuel and CO2 savings from day one and 20 percent by 2020 as well as 50 percent noise reduction. With more than 6,200 orders received from over 100 customers, the A320neo Family has captured some 60 percent of the market.

Flyplassikkerhet - "Walk Through" sjekk av passasjerer - Curt Lewis video

New passenger scanner uses space technology to speed up airport security


A super-sensitive passenger scanner that reveals hidden security threats is being trialled at Cardiff Airport in the UK.


The walk-through scanner, which uses space technology to image human body heat, is the result of a collaboration between Sequestim Ltd. and Cardiff University scientists.

Computer learning allows the scanner to distinguish between threats and non-threats but without the need for passengers to keep still or remove outer clothing.

Globally, around 12 million passengers travel by plane every day on 120,000 flights.

The technology has the potential to cut queues at airport terminals as it screens people on the move. It will also impact on the effectiveness of security and help keep passengers safe.

"Passenger numbers are expected to double in 20 years, putting airport security facilities under immense pressure," said Ken Wood, Sales and Marketing Director of Sequestim Ltd, a joint venture between Cardiff University and QMC Instruments Ltd.

"Our scanner combines a number of world-leading technologies developed by our team here in the UK. It uses the human body as a source of "light", in contrast with existing scanners which process reflected and scattered millimetre-waves while the passenger is required to strike a pose."

"Our system only needs a few seconds to do its work. Passengers walking normally through security would no longer need to take off coats and jackets, or remove personal items such as phones."
The trial takes place privately, by invitation only, from 4 to 7 December 2018 and will not affect passenger journeys.

The project is one of eight to receive some of the £1.8m funding made available by the UK Government earlier this year through a Defence and Security Accelerator themed competition. Part of the five year Future Aviation Security Solutions (FASS) programme, the multimillion-pound initiative seeks innovative ideas such as this new passenger scanner to help strengthen aviation security.

Originally built to study the furthest reaches of the universe, the technology used is so sensitive it could see a 100W light bulb at a distance of 500,000 miles (twice the distance to the Moon.)


The scanner quickly "learns" the difference between items that can and cannot be taken onto an aircraft, reducing the risk of false alarms which inconvenience passengers and slow down screening.
"The detector technology was originally developed to study the most distant astronomical phenomena. For example, we study how stars are born from gigantic clouds of gas and dust," explained Mr Wood.

"It detects millimetre-waves, which are just like visible light but at a wavelength more than one thousand times longer. The ability of the scanner to reveal hidden objects has also attracted interest from Border Force, responsible for the UK's frontline border control operations at air, sea and rail ports.

The airport trial aims to prove that passive terahertz imaging is robust, versatile, fast and convenient.

UK Aviation Minister Liz Sugg said: "We have a proud history of innovation here in the UK and passenger safety across all modes of transport remains an important priority for the government. The Future Aviation Security Solutions programme demonstrates our support for pioneering projects that can help to reduce security threats in airports. I am pleased to see that the funding awarded to Sequestim has helped the team take space technology and trial it as part of a new passenger screening system at Cardiff Airport."

Cardiff Airport was bought by Welsh Government for £52m in 2013. Nearly 1.5m passengers passed through the airport in 2017. The trial of the passenger scanner in December represents a first for Wales, and a local collaboration with enormous impact potential.

First Minister of Wales, Carwyn Jones, said: "Welsh Government and Cardiff Airport are delighted to be hosting the proof-of-concept trial of Sequestim's innovative technology. This cutting-edge security camera not only promises a huge improvement in our experience of air travel, but also brings with it the prospect of job creation as Sequestim aims to manufacture future scanners here in Wales."


The purpose of the trial is for key members of industry, the Centre for the Protection of National Infrastructure, the Civil Aviation Authority and other government bodies including BorderForce to see the technology in action.

Ny E190-E2 med spesielt utseende - Curt Lewis

Air Astana takes delivery of its first Embraer E190-E2 jet


Air Astana, the flag carrier of Kazakhstan, has received its first of five Embraer E190-E2 jets. The aircraft is registered as P4-KHA and was ferried from Brasil to Kazakhstan last week.

To draw global attention to the threat of extinction of the snow leopard, which is native to the mountain ranges in southern Kazakhstan, the brand new jet wears a special Air Astana 'Snow Leopard' livery.


The new generation Embraer E190-E2 aircraft will replace older E190s in the fleet. The airline currently operates a fleet of nine Embraer E190 aircraft, with the first aircraft having entered service in 2011.
