Riad Dar Najat
This Riad is very well located just near the Jemah-El-Fnaa place. It is very well renewed, nicely arranged and very quiet.
The team is nice, very friendly and available : many good tips, friendly discussions and easy laughs ! The breakfasts are also very good.
The team had organized a party for new year's eve, with belly dancers and a Gnawa music band : very cool !

There is also a jacuzzi : as we were in winter, the water was a bit cold.

The river is quite slow moving in this part of Yosemite valley, in contrast to further downstream where it is a raging torrent. This makes for quite pleasant reflections.

3张14mm定焦横构图竖拼,总算把Swfc从天到地给拍全了,透视变形也挺难控制。由于太高,低层较难拍,只能站在边缘伸出手去盲拍了几张,金茂顶层的上面风很大,晃晃的,对有点恐高的我是个小考验。不过站在城市的顶端的感觉总是奇妙的。

周末开始6天的休假,不算旅行,只是放松一下,也希望有个好天气,出几张好片子。也希望回来后我的FLICKR能够正常点。

Soviet WWII Fighter Aircraft Lavochkin La-5. 1942. Советский истребитель Лавочкина Ла-5.

Soviet WWII Fighter Aircraft Lavochkin La-5. 1942. Советский истребитель Лавочкина Ла-5.

The Lavochkin La-5 (Лавочкин Ла-5) was a Soviet fighter aircraft of World War II. It was a development and refinement of the LaGG-3 and was one of the Soviet Air Force's most capable types of warplane.
Development
The La-5's heritage began even before the outbreak of war, with the LaGG-1, a promising yet underpowered aircraft – turning a full circle, for example, took 20 seconds. The LaGG-3 was a modification of that design that attempted to correct this by both lightening the airframe and fitting a more powerful engine. Nevertheless, this was not enough, and the lack of power remained a significant problem.

In early 1942, two of the LaGG-1 and -3's designers, Semyon Lavochkin and Vladimir Gorbunov, attempted to correct this deficiency by experimentally fitting a LaGG-3 with the more powerful Shvetsov ASh-82 radial engine. Since the LaGG-3 was powered by an inline engine, they accomplished this by grafting on the nose section of a Sukhoi Su-2 (which used this engine). By now, the shortcomings of the LaGG-3 had caused Lavochkin to fall out of Joseph Stalin's favour, and factories previously assigned to LaGG-3 construction had been turned over to building the rival Yakovlev Yak-1 and Yak-7. The design work required to adapt the LaGG-3 to the new engine and still maintain the aircraft's balance was undertaken by Lavochkin in a small hut beside an airfield over the winter of 1941-1942, all completely unofficially.

When the prototype took flight in March, the result was extremely pleasing - the fighter finally had a powerplant that allowed it to perform as well in the air as it had been supposed to on paper. After flying, the LaG-5 (the change in name reflecting that one of the original LaGG designers was no longer with the programme), Air Force test pilots declared it superior to the Yak-7, and intensive flight tests began in April. After only a few weeks, the design was modified further, cutting down the rear fuselage to give the pilot better visibility.

By July, Stalin ordered maximum-rate production of the aircraft, now simply known as the La-5 and the conversion of any incomplete LaGG-3 airframes to the new configuration. The prototype was put in mass production almost immediately in factories located in Moscow and in the Yaroslav region. While still inferior to the best German fighters at high altitudes, the La-5 proved to be every bit their match closer to the ground. With most of the air combat over the Eastern Front taking place at altitudes of under 5,000 m (16,404 ft), the La-5 was very much in its element. Its rate of roll was excellent.

Further refinement of the aircraft involved a fuel-injected engine, further lightening of the aircraft, and fixed slats to improve all-round performance. This was designated the La-5FN and would become the definitive version of the aircraft. A full circle turn took 18–19 seconds. Altogether, 9,920 La-5s of all variants were built, including a number of dedicated trainer versions, designated La-5UTI. Several La-5s had three Berezin B-20 cannon installed in the nose capable of a salvo of 3.4 kg/s rounds. Further refinements of the aircraft would lead to the Lavochkin La-7.

A number of La-5s continued in the service of Eastern Bloc nations after the end of the war, including Czechoslovakia.
Flying the La-5

In the summer of 1943, a brand-new La-5 made a forced landing on a German airfield providing the Luftwaffe with an opportunity to test-fly the newest Soviet fighter. Test pilot Hans-Werner Lerche wrote a detailed report of his experience.[1] He particularly noted that the La-5FN excelled at altitudes below 3,000 m (9,843 ft) but suffered from short range and flight time of only 40 minutes at cruise engine power. All of the engine controls (throttle, mixture, propeller pitch, radiator and cowl flaps, and supercharger gearbox) had separate levers which served to distract the pilot during combat to make constant adjustments or risk suboptimal performance. For example, rapid acceleration required moving no less than six levers. In contrast, contemporary German aircraft, especially the BMW 801 radial-engined variants of the Focke-Wulf Fw 190 front line fighter, had largely automatic engine controls with the pilot operating a single lever and electromechanical devices, like the Kommandogerät pioneering engine computer on the radial-engined Fw 190s, making the appropriate adjustments. Due to airflow limitations, the engine boost system (Forsazh) could not be used above 2,000 m (6,562 ft). Stability in all axes was generally good. The authority of the ailerons was deemed exceptional but the rudder was insufficiently powerful at lower speeds. At speeds in excess of 600 km/h (370 mph), the forces on control surfaces became excessive. Horizontal turn time at 1,000 m (3,281 ft) and maximum engine power was 25 seconds.

In comparison with Luftwaffe fighters, the La-5FN was found to have a comparable top speed and acceleration at low altitude. It possessed a higher roll rate and a smaller turn radius than the Bf 109 and a better climb rate than the Fw 190A-8. The Bf 109 utilizing MW 50 had superior performance at all altitudes, and the Fw 190A-8 had better dive performance. Lerche's recommendations were to attempt to draw the La-5FN to higher altitudes, to escape attacks in a dive followed by a high-speed shallow climb, and to avoid prolonged turning engagements.

The La-5 had its defects. Perhaps the most serious being the thermal isolation of the engine, lack of ventilation in the cockpit, and a canopy that was impossible to open at speeds over 350 km/h. To make things worse, exhaust gas often entered in the cockpit due to poor insulation of the engine compartment. Consequently, pilots ignored orders and frequently flew with their canopies open.[2]

In general, Soviet pilots appreciated the La-5 as an effective fighter. "That was an excellent fighter with two cannons and a powerful air-cooled engine", recalled pilot Viktor M. Sinaisky. "The first La-5s from the Tbilisi factory were slightly inferior, while the last ones from the Gorki plant, which came to us from Ivanovo, were perfect. At first we received regular La-5s, but then we got new ones containing the ASh-82FN engine with direct injection of fuel into the cylinders. It was perfect. Everyone was in love with the La-5. it was easy to maintain too."[3] Nevertheless La-5 losses were high, the highest of all fighters in service in USSR, not considering those of the Yak-1. In 1941-45, VVS KA lost 2,591 La-5s, 73 in 1942, 1,460 in 1943, 825 the following year and 233 in 1945.
