The World’s Smallest RC Helicopter for US$100

By - October 31, 2006 2 Pictures
November 1, 2006 The lines between manpackable UAVs for the military and high end Radio Controlled toys blurred some time ago, and when we saw the latest toy from Interactive Toy Concepts, we began to wonder just how far this trend might go, given the trend towards miniaturisation of everything. The Micro Mosquito is claimed to be the Worlds smallest, lightest and quietest full function indoor R/C helicopter and weighs only 15 grams – that’s hellishly impressive, but the startling bit is the retail price of just over US$100. We’re sure it’s not the smallest, because military contractors around the world no doubt have much smaller versions in the labs – but this one does have the advantage of being available on retail shelves within the next few weeks and is certain to be there only a short while.

UK's VTOL Harrier Jets upgraded

By - October 10, 2006 3 Pictures
October 11, 2006 An upgraded version of the iconic Vertical Take-Off and Landing (VTOL) Harrier GR9 aircraft has entered service with the United Kingdom’s Royal Navy and Royal Air Force after a GBP500 million improvement package. The GR9 programme provides updated digital systems and enhanced operational capability that will allow the RAF to hit a wider range of targets harder, at longer range, with greater precision and with less risk to aircrew. A number of new systems have been or will be integrated onto the GR9, linked by a new on-board computer. These include the Precision Guided Bomb and infra red & television variants of the Maverick missile. Also included is the Successor Identification Friend or Foe (SIFF) system, which will make the aircraft less vulnerable in an operational environment. The GR9 will also carry the Brimstone missile which will enable it to attack up to 12 ground targets simultaneously compared with just two with the GR7. Read More

Hybrid Manned/Unmanned Light Helicopter Makes First Flight

By - October 9, 2006 2 Pictures
October 10, 2006 This photo shows the first of two newly designed A/MH-6X light-turbine helicopters lifting off for the first time late last month at Boeing’s Rotorcraft Systems facility in Mesa, Arizona. The flight was a significant milestone in the continuing development of the versatile hybrid manned/unmanned military aircraft which combines the proven performance of the A/MH-6M Mission Enhanced Little Bird (MELB) with the unmanned aerial vehicle technologies of the Unmanned Little Bird (ULB) Demonstrator, a modified MD 530F civil helicopter that has been in development since 2004. Aircraft performance will be similar to the ULB Demonstrator with an additional 1,000 pounds of payload that can be used for increased range, endurance or mission hardware. Total payload for the ULB Demonstrator is greater than 2,400 pounds. Read More

Obstacle Cable and Terrain Avoidance System (OCTAS) showcased for rotorcraft

By - July 21, 2006 3 Pictures
July 22, 2006 BAE Systems has developed a day/night, all-weather, all-obscurant capability that enables helicopter pilots to fly safely and avoid obstacles, including cables, in darkness, bad weather, and brown-out conditions. The Obstacle Cable and Terrain Avoidance System (OCTAS), being demonstrated this week at the Farnborough International Airshow, combines a Radar Cable Detection (RCD) system with BAE Systems’ TERPROM terrain avoidance system and a pilot display. It offers a low-cost way to significantly improve pilot situational awareness and can be expanded through addition of other sensors and capabilities to suit specific missions. Read More

Little Bird - helicopter without a pilot

By - July 12, 2006 7 Pictures
July 13, 2006 Just three months ago we wrote about the AH-64D Apache Longbow helicopter demonstrating the ability to control an unmanned aerial vehicle (UAV) weapon payload using the Unmanned Little Bird (ULB) UAV technology demonstrator as the remote vehicle. Now the Little Bird has achieved a major milestone in its development by flying unmanned for the first time. The payload for the first unmanned flight weighed 740 pounds, but could have carried an additional 550 pounds of payload. A more advanced configuration, which is expected to make its first flight later this summer, adds an additional 800 pounds of payload. Add all that up and the weapon payload could be as great as 2000 pounds, flown autonomously while its payload or sensor is guided from a remote site or another platform. We suddenly see a future of battlefields with flocks of warbirds, all networked, armed and very, very dangerous ... and not a pilot in sight! Read More

ScanEagle UAV demonstrates maritime capabilities

By - May 17, 2006 5 Pictures
May 18, 2006 Last year we wrote about the ScanEagle UAV and its success in supplying U.S. Marines in Iraq with critical real-time tactical battlefield imagery. This time, we’re writing about the adaptation of the ScanEagle as a low-cost intelligence, surveillance and reconnaissance (ISR) platform for amphibious operations. Currently being trialled for its maritime capabilities by the UK Ministry of Defence (MoD) in "Trial Vigilant Viper" off the coast of Scotland, the ScanEagle completed ten autonomous flights with full launch and recovery from a Type 23 Frigate in rough sea conditions. A small UAV such as the ScanEagle can significantly increase the capability of a boat, and the missions conducted during the trial illustrate this enormous potential for land and sea surveillance, beach reconnaissance, force protection, maritime interdiction and naval gunfire support.

SkyTote - the VTOL UAV that transitions into horizontal flight

By - April 7, 2006 5 Pictures
April 8, 2006 One of the greatest difficulties with vertical take-off and landing (VTOL) aircraft is that they invariably don’t have high speed as one of their attributes. The principles are well explained in our article about the Cartercopter, and it’s one of the prime reasons the US military has persisted with the V-22 Osprey. There has been much emphasis on the development of new unmanned air vehicles (UAVs) in recent times, and development imperatives have often been torn between the various needs for UAVs that can quickly move from target to target yet loiter as a fixed and stable platform, all the while operating with no launch and retrieval infrastructure. One of the planet's most innovative companies, Aerovironment, has proposed an innovative configuration known as the Skytote to meet all of these needs. The SkyTote is a novel UAV using dual counter rotating propellers that will take off and land vertically like a helicopter, but also transition into horizontal flight like a conventional aircraft for efficient point-to-point operation. This complex vehicle uses an intricate drive system to allow helicopter operations with cyclic and collective control, as well as blade pitch control, combined with normal aircraft control surfaces in conventional flight operations Read More
