The Scorpion Attack Aircraft

The Scorpion Intelligence, Surveillance and Reconnaissance (ISR) / Strike aircraft is being developed by Textron AirLand, a joint venture between Textron and AirLand Enterprises.

The aircraft is capable of performing air defence, irregular warfare, border patrol, maritime security, disaster relief and counter-drug missions.

The development of the Scorpion aircraft was commenced in January 2012, with the objective of producing the most economical jet-powered light attack aircraft in the world.

Excerpt

Conducted from McConnell AFB in Kansas on 22 December, the 1h 42min first flight “verified the avionics and aerodynamic performance, as well as a number of aircraft systems”, the Textron company says. Registered as N530TX, the jet “performed extremely well”, it adds.

Design improvements introduced with the new aircraft include a simplified landing gear, enhanced aft horizontal stabiliser and an additional 4˚ of sweep to its wing.

In the cockpit, the Scorpion gets a new head-up display, hands-on-throttle-and-stick controls and a Garmin G3000-based avionics suite. “The newly configured avionics system features a large, high-definition display complemented by touch-screen controllers and provides more mission capability in the forward cockpit position, additional navigation capability in the rear cockpit position and overall weight savings,” the airframer says.

Excerpt

Changes to the production-conforming Scorpion included 4 degrees of sweep to the wings, an enhanced aft horizontal stabilizer and a simplified landing gear design.

Officials from Textron AirLand, a unit of Textron Inc., said during the test flight that they verified the Scorpion’s newly configured Garmin G3000 avionics and aerodynamic performance as well as a number of other aircraft systems.

Now, the revamped twin-engine, multimission jet will undergo an assessment by the Air Force Airworthiness Office.

The Scorpion aircraft features an all-composite airframe and structure powered by twin turbofan engines. Its fuselage integrates a tandem cockpit, retractable sensor package, internal payload bay and external mounts for precision and non-precision munitions. The corrosion-resistant airframe offers 20,000 hours of service life.

The Scorpion aircraft accommodates two pilots in tandem layout. The two cockpits are equipped with advanced multifunction colour displays, providing the details of flight characteristics, aircraft operation, navigation and armament data.

The avionics suite integrates inherent Flight Management System (FMS), Class-B Terrain Awareness and Warning System (TAWS), engine indication and crew alerting system (EICAS), dual Air Data, Attitude and Heading Reference Systems (ADAHRS), dual GPS/Satellite Based Augmentation Systems (SBAS) and integrated moving maps.

The nigh-vision compatible cockpit also offers instrumentation for weather radar control, display of external video and digital flight data recording.

Thales successfully integrates I-Master radar on Textron’s Scorpion light attack and ISR aircraft: Here

defence24.pl

Excerpt

Thales and Textron AirLand announced today, June 17, 2015, at the International Paris Air Show 2015, that they have successfully jointly integrated Thales’ I-Master radar on to Textron AirLand’s Scorpion light attack and ISR aircraft. The addition of the radar into the Scorpion’s mission system compliments the Intelligence, Surveillance and Reconnaissance (ISR) sensor suite which already includes a high end EO/IR capability.

THALES I-MASTER RADARS

I-MASTER is Thales’ new lightweight high performance combined Synthetic Aperture Radar (SAR) and Ground Moving Target Indicator (GMTI). I-MASTER weighs only 30kg, and provides the perfect balance of capability, cost, weight and power consumption for use onboard a wide range of unmanned air vehicles (UAV)helicopters, small fixed wing aircraft and tilt rotor platforms.

High performance imaging radars are now essential in any programme that requires an all weather ISTAR (Intelligence, Surveillance, Target Acquisition and Reconnaissance) capability. To date, high quality SAR/GMTI radars have been too heavy and costly for tactical UAVs or small manned aircraft.

The low weight of I-MASTER means that a combined SAR/GMTI capability can be added to tactical UAVs either in addition to or instead of electro-optic (E/O) sensors. I-MASTER is also designed to fit existing E/O payload mountings. On smaller air vehicles, which are able to carry just one payload, this unique feature enables the sensor to be exchanged within a few minutes. This capability will allow the platform’s role to be quickly adapted as the mission tempo and the environment changes. For larger air vehicles, able to carry more than one payload, collaborative targeting using both SAR/GMTI and EO packages greatly increases the options available to the field commander.

I-MASTER builds upon Thales’ radar expertise that exists in depth in both the UK and France. This expertise has made it possible for Thales to develop a SAR/GMTI radar sensor that not only delivers high performance but also sufficiently light and inexpensive to be fitted to Tactical UAVs. I-MASTER provides an all-weather capability, which dramatically increases Tactical UAV mission effectiveness. High quality imaging is now possible in hostile environments such as cloud and smoke. The ability to image at long stand-off ranges improves UAV survivability by distancing the air vehicle from potential ground fire.

I-MASTER incorporates a high performance Ground Moving Target Indicator (GMTI) able to detect both vehicle and infantry movements at ranges up to 20km. Very low speed targets can be detected through the use of multi-channel processing.

With 360-degree coverage and an innovative stabilised antenna, I-MASTER provides high quality images over a wide area from small air vehicles in a wide range of flight conditions.

Key features

  • High-fidelity, 360° all-weather, day/night surveillance
  • Ground moving target indication (GMTI) & synthetic aperture radar (SAR) modes
  • Compact, single line replacement unit – interchangeable with electro optic/infrared turret sensors
  • Ideal for rotary, fixed-wing, manned and unmanned platforms
