Slazem se sa tobom, i Dinja je predlagao tu kombinaciju kao najoptimalniju.

Toni ::Ih za njega kukamo isto toliko godina a cak vise i nije Poljak nego je i on sad Airbus.
Zar nije Sikorsky/Lockheed Martin vlasnik PZL-a?

A izvini jeste, ja sam pomesao. PZL Varsava je otisla pod EADS a PZL Milec pod Lokid.

Doduse Spanci vise neprave C-212 a uzimati avion iz Indonezije je...Filipini cekali taj Skadar na Bojani godinama.

Da, već smo čini mi se zaključili da je M28 jedini preostali u klasi. Dakle ili to kao zamena za Anušku, ili se pomiriti sa manjkom zadnjih kargo-vrata i uzeti možda Twin-Otter, L-410, Kodiak, ili onu novu Fedex Cesnu. Mada sumnjam da je bilo koji od njih jeftiniji od Jenki-Poljaka. Svakako ima posla za bar dva takva, zar ne?

Marko Marković ::Za naše uslove i potrebe, kombinacija C-295 i PZL M28 bi bila sasvim dovoljna.

darkangel ::Eto na taj sam izvestaj mislio za C27J (Shone89 je moj stari nalog).

U medjuvremenu je C295 dobio vinglete i pojacana je snaga motora pa se dobilo nesto na povecanom doletu te su rezultati nesto bolji nego kada je Dinja odgovarao ali ne drasticno. Istina i C27J je u medjuvremenu dobio vinglete.

Koliko znam, vingleti pomažu kod performansa oko 1 tone. Inače ono što se napisali kod stvarnih performansa ovih avijona su daleko od onih, koje se reklamiraju. Vjerovatno bi tako možda bilo najbolje, da se umjesto ovih avijona uzme pokoji herkules. Barem C27j i nije toliko jeftiniji.

AN-2 standardna dnevna rutina u Nisu jedno 5-6 tura padobranaca svaki letacki dan. Tako da ima.

M-28 su oko 4-5 miliona komad placali razni civili.

To je jos jedan podatak kojim se lako moze manipulisati jer se ne precizira na sta se odnosi. Da li dozvoljava recimo 7 tona a ne 6 na istoj razdaljini nebitno o kojim se aerodromima radi, ili je to mozda (a ja bih rekao da jeste ) stvar koja je vezana za aerodrome sa velikim nadmorskim visinama (Andi, Himalaji) gde zbog nadmorske visine pada efikasnost motora pa se posledicno smanjuje nosivost.

Ono sto je sigurno je da nesto jaci motor (tacnije pojacana snaga u odredjenim rezimima) i vingleti koji poboljsavaju aerodinamiku daju bolje preformanse ali je pitanje pod kojim uslovima je ta navedena nosivost od dodatne tona ostvariva, jer sigurno nije u opstem slucaju.

Opet zavisi od potreba svake konkretne zemlje i njene situacije (privredne, politicke...) ali i od mogucnosti i zelja vazduhoplovstva. Nije moguce dati odgovor koji vazi za sve.

I C-295 i C-27J su dobili vinglete tako da su sada bazni modeli C-295W i C-27J NG i vec su prodati kupcima.

C-295W

Citat:Airbus DS did not disclose a contract value, which would likely include infrastructure, training, and support, or provide a delivery timeline. While the company noted only that the aircraft is to be delivered in its baseline transport configuration, this now includes winglets and modified engines for greater fuel economy and/or range. This version is designated C295W.

According to Airbus DS, the winglet and engine modifications add 3-6% in overall performance, with just a 30 kg weight penalty. Figures released by the company show an increase of 320 km in the aircraft's range and 30 minutes of additional time on station. In addition, the engine upgrade alone affords an extra 1.5 tonnes in payload in hot and high conditions.

C-27J NG Vingleti + nova avionika, nov meteo radar...

Citat:Their introduction allows increasing the Take-off Weight (TOW) of the aircraft whenever there are limitations on the climb gradient. For example, if in order to take off from a runway and due to certain altitude and temperature conditions (typical conditions in which a series of performance penalties are recorded for each aircraft), there are TOW limitations in order to respect the gradient minimum climb on the second segment in single-engine conditions, thanks the winglets presence it will be possible to increase the weight by 1,000 kg. This increase is always obtainable, regardless of the altitude and temperature at which the airport is located. This gain on TOW will therefore be available to the C-27J NG user, who will be able to exploit it either for increasing the payload or the fuel load. In the Next Generation version, structural changes have also been made to increase the Maximum Take-off Weight (MTOW) by 1 tonne and the maximum transportable payload by 3 tonnes.

In addition to this, the winglets allow the C-27J, at the same weight, to increase its operational ceiling in single-engine conditions by 500 ft. This last benefit is also independent of the temperature. Asked on beneficial effects on fuel consumption, Leonardo pointed out that the winglets have been developed and optimised to reduce the intensity of the extremity eddies at high angle of attack, thus further improving the climbing characteristics in single-engine conditions and increasing the availability of payload, as stated before. However there are also improvements in other areas of the aircraft’s flight envelope, i.e. aircraft controllability, in particular when flying at slow speed. No winglet retrofit kit has been developed, therefore these performance benefits will be available only to C-27J NG customers.

Citat:Among those new systems the Spartan NG cockpit includes the Future Air Navigation System (FANS) 1/A+ data link that allows aircraft to be seen by ATC in areas where radar is not practical, the TCAS II 7.1 that resolves safety issues with the current TCAS II, a Cat. II Instrumental Landing System (ILS), and an enhanced video Terrain Awareness Warning System (TAWS). The new cockpit does not look only at navigation in civil airspace, but has it been fitted with state-of-the-art systems in place of legacy ones that can also facilitate the pilots task in tactical missions. Among those we find five new Colour Multipurpose Display Units, which feature new and enhanced LED lighting and panels that increase pilots’ efficiency, a dual redundant Flight Management System, and two Digital Autopilot-Flight Director Systems with auto-throttle capabilities. Leonardo’s Next Generation tactical transport aircraft has also been fitted with a new weather radar, new radio navigation, enhanced satellite communications and radio communication capabilities, a new intercommunication system, and the Mode 5 IFF/ADS-B (Identification Friend or Foe/Automatic Dependent Surveillance-Broadcast) with tactical VNAV (Vertical Navigational) and Search and Rescue modes. Moreover, former avionics and general systems interface boxes have been replaced with new equipment provided by Leonardo’s Electronics.
