The IAI Heron (Machatz-1) is a medium-altitude long-endurance unmanned aerial vehicle (UAV) developed by the Malat (UAV) division of Israel Aerospace Industries. It is capable of Medium Altitude Long Endurance (MALE) operations of up to 52 hours' duration at up to 10.5 km (35,000 ft).
The plane and onboard computer are built by Malat, a division of Israel Aerospace Industries, based on the IAI Heron. The French Air Force ordered three planes and two ground control stations. The SIDM entered service in June 2008 in the Drone Experimentation Squadron 1/330 Adour, in Cognac, a unit of the Centre des expérimentations militaires ...
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).

In 2010 IAI offered the Eitan, under a teaming agreement with Rheinmetall, in pursuit of the German Air Force's long-term "Saateg" MALE UAV requirement. [16] On 21 May 2014, IAI signed a deal with Airbus to team up on a bid for a bridging contract to supply the German armed forces with the Heron TP from 2015 until 2020. A current contract ...
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
Waffle slab foundations adhere to International Building Code requirements. By 2008, most states put into effect the changes adopted in the 2006 IBC and, in regards to foundations, the on-grade mat foundation has become a more attractive design because, as an engineered system, it already accommodates the 2008 design recommendations, and required no major modifications to bring it into compliance.
In June 2014, Switzerland's procurement agency selected the Hermes 900 to meet the nation's requirement. The design had been in competition with IAI Heron to replace the RUAG Ranger UAV (ADS 95) of the Swiss Air Force. Planned was to replace the 15 Ruag Rangers with Six Hermes 900 (ADS 15) by 2019.
