Walkaround vol.26: Sd.Kfz 161 Panzer IV


Subject: Sd.Kfz161 Panzer IV
Location: Musée des Blindés, Saumur, France
Comments:The Panzerkampfwagen IV (PzKpfw IV), commonly known as the Panzer IV, was a German medium tank developed in the late 1930s and used extensively during the Second World War. Its ordnance inventory designation was Sd.Kfz. 161.The Panzer IV was the most widely manufactured German tank of the Second World War, with some 8,500 built. The Panzer IV was used as the base for many other fighting vehicles, including the Sturmgeschütz IV assault gun, Jagdpanzer IV tank destroyer, the Wirbelwind self-propelled anti-aircraft gun, and the Brummbär self-propelled gun. The Panzer IV saw service in all combat theaters involving Germany and was the only German tank to remain in continuous production throughout the war. Upgrades and design modifications, intended to counter new threats, extended its service life. Generally, these involved increasing the Panzer IV's armor protection or upgrading its weapons, although during the last months of the war, with Germany's pressing need for rapid replacement of losses, design changes also included simplifications to speed up the manufacturing process. The Panzer IV was partially succeeded by the Panther medium tank, which was introduced to counter the Soviet T-34, although the Panzer IV continued as a significant component of German armoured formations to the end of the war. The Panzer IV was the most widely exported tank in German service, with around 300 sold to Finland, Romania, Spain and Bulgaria. After the war, Syria procured Panzer IVs from France and Czechoslovakia, which saw combat in the 1967 Six-Day War. 8,553 Panzer IVs of all versions were built during World War II, with only the StuG III assault-gun/tank destroyer's 10,086 vehicle production run exceeding the Panzer IV's total among Axis armored forces

Diorama vol.1: Ardennes street (UPDATED)





Subject:
Ardennes street
Scale:
1/35
Manufacturer:
Miniart
Price
US$35,00
Description
Limited run injection molded kit with vacuum formed parts. No decals
Comments
I always saw diorama building as one of the most challenging parts of plastic modeling.  The capacity of taking a mental image and turning it into a 3-d scenario was a long way ahead of my skills.
A few years ago a learned about this Miniart kits for diorama building. At first, the idea of working with vacuum formed parts was something that kept me away from this kit as i think that this type of model forms lack detail and are too difficult to work with. Just recently a model company started to import a few of these kits to Brazil. As the price became more attractive, i decided to give a chance to these kits. I was not disappointed!
I build it at first as an out-of-the-box project, just to see what i could get. It was a nice project, but of course not very realistic. Then recently i decide to add some ruble around the ruined house and improve the grass and other minor details of the kit. Here you can see how the two projects ended.

Aircraft Walkaround vol.81 : Lockheed F-22 Raptor


Subject: Lockheed F-22 Raptor
Location: USAF Museum, Dayton, Ohio, USA, 2014
Comments:The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and did its final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. After a protracted development and despite operational issues, the USAF considers the F-22 critical to its tactical air power, and says that the aircraft is unmatched by any known or projected fighter. The Raptor's combination of stealth, aerodynamic performance, and situational awareness gives the aircraft unprecedented air combat capabilities. The high cost of the aircraft, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35 led to the end of F-22 production. A final procurement tally of 187 operational production aircraft was established in 2009, and the last F-22 was delivered to the USAF in 2012.

Engine walkaround vol.22: Pratt & Whitney YF119 jet engine


Subject: Pratt & Whitney YF119 jet engine
Location: USAF Museum, Dayton, Ohio, USA, 2014
Comments: The Pratt & Whitney F119 (company designation PW5000) is an afterburning turbofan engine developed by Pratt & Whitney for the Lockheed Martin F-22 Raptor advanced tactical fighter. The engine delivers thrust in the 35,000 lbf (160 kN) class, and is designed for supersonic flight without the use of afterburner (supercruise). Delivering almost 22% more thrust with 40% fewer parts than conventional, fourth-generation military aircraft engine models, the F119 allows sustained supercruise speeds of up to Mach 1.8. The F119's nozzles incorporate 2D thrust vectoring technology. These nozzles direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability.
