LIPNUR Belalang
The LIPNUR Belalang ( id, Grasshopper) was a military trainer aircraft built in small numbers in Indonesia by LIPNUR in the late 1950s. It was essentially a Piper L-4J Grasshopper converted to give it a low wing. The NU-85 prototype flew for the first time on 17 April 1958 and the first production of NU-90 took place in 1959. The aircraft was operated by Indonesian Air Force. Indonesian Army and Indonesian Civil Aviation Institute at Curug, Tangerang also used this aircraft. Design and development In 1949-1950 period, the Indonesian Air Force (then called AURI) received around 60 Piper L-4J Grasshoppers from Royal Netherlands East Indies Air Force as part of the transfer of sovereignty. AURI used them as liaison and primary trainer aircraft. In 1957, AURI decided that their ex-Dutch L-4Js, which were powered by 65 hp Continental O-170, were already ageing and needed to be replaced. The L-4Js also has high wing so its aerobatic performance is very limited. Nurtanio Pringgoad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Continental O-190
The Continental O-190 (Company designations C75 and C85) is a series of engines made by Continental Motors beginning in the 1940s. Of flat-four configuration, the engines produced 75 hp (56 kW) or 85 hp (63 kW) respectively.Teledyne Continental Motors: ''Continental Aircraft Engine Operator's Manual'', pages 4-5. Teledyne Continental Motors, FAA Approved December 1980. Continental Form No. X30012 The two variants shared the same bore, stroke and compression ratio. The C85 produced ten extra horsepower by virtue of having a maximum permissible rpm of 2575 versus the 2275 of the C75. The C75 was in production from 1943 to 1952 and the C85 from 1944 to 1970.

LIPNUR Kunang
__NOTOC__ The LIPNUR Kunang was a single-seat sports aircraft built in Indonesia that first flew in 1958 in the hope that it would inspire interest in aviation amongst Indonesian youth. The only example that was built was subsequently grounded. It was a single-seat monoplane of conventional layout with fixed tailwheel undercarriage.

Flat-four
A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indonesian Army Aviation Command
The Indonesian Army Aviation Center ( id, Pusat Penerbangan Angkatan Darat) abbreviated Puspenerbad or simply Penerbad is the Army aviation unit of the Indonesian Army which has a means to support the combat mobility of the troops and also transport Infantrymen for Air assault operations. Penerbad is considered as an integral part mainly in cases of Air assault operations parallel to other Armament Corps of the Indonesian Army. Other additional tasks conducted by the unit can be implemented to support non-combat operations such as Search and rescue, Disaster relief, etc. History The Indonesian army aviation was born in 1959 - the beginning of Guided Democracy - when the doctrine of Heliborne Troops or Air Mobile was being developed in various countries. In Sarawak during the Confrontatiion, the British Special Air Service, SAS launched an air assault operation with Westland Wessex helicopter containing 16 personnel.

Bracing (aeronautics)
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more impo ...
