GRIPEN SMART FROM THE START

07 December 2016

Smart has become synonymous with Gripen, we take a look to see just how this has happened.

Just what is ‘smart thinking’? Although for many ‘Smart’ has just become a fashionable term for marketing tech, for us it’s long been a part of our design DNA.

The first Gripen fighter took to the skies in the early eighties. Smart had not yet become synonymous with the latest must-have mobile phone. Could you use it to describe the thinking at Saab at the time? Absolutely. One could argue that the Gripen system could not have been achieved without it. 

The first Gripen was born of a specific need for a new type of fighter system. Not only did it have to out-perform other fighters on numerous levels but it also had to answer budget constrictions set by the Swedish ministry of defense. Gripen was not only to be a highly technologically ‘smart’- fully computerized for example, at a time when neither the computers nor the systems existed.  But additionally, Gripen was born of a smart design mentality rooted in evolutionary thinking. Put simply by Lars Sjöberg, head of Research and Design at Saab’s business area Aeronautics, “the smart process is to make the complex simple”.

Systems thinking and breaking the cost curve

The thinking was not only to create a fighter aircraft. It was to create a system that would evolve. A system that could, as a result of using split avionics, be updated without the updates affecting essential flight systems. Designers and strategists alike knew that a total redesign of the fighter aircraft each decade, as was the traditional method, was going to be extremely costly. Within the industry the development costs for new fighters were increasing at an unsustainable rate. Something had to be done to break the cost curve. Aside from costs the Gripen team were uniquely aware, that the old ways would not allow them enough time to adapt to future threat horizons fast enough. The Gripen system would have three-year cycle updates. Lifecycle costs were to be driven down, maintenance costs were made minimal. Efficiency became the watchword. As a result a perfectly balanced fighter system was created. Good in every operational level, yet affordable to acquire and affordable to fly.

Going lean

At Saab we define efficiency as a lean, model-based development process. Used when developing Gripen, 3D modeling techniques greatly helped to reduce risk. The method also helps each engineer to visualize and access the overall project. As Sjöberg explains, “it should be possible for a newly recruited engineer to enter my department to be productive as fast as possible”. The same computer models can be used throughout the entire lifecycle of each plane and for and the three-year cycle updates. There are no more blue prints or the 50,000 technical drawings that would usually be associated with such a project.

Ultimately it is Saab’s smart systems and smart thinking that have delivered such positive benefits – from the bottom line to overall efficiency and development.

GRIPEN E DESIGNED TO BE FUTURE-PROOF

21 June 2016

Pilots like nothing better than having the latest fighter, but few pilots ever fly a plane capable of evolving to meet an uncertain future.

Able to supercruise, and equipped with a weapons system that is more flexible than ever before, the Gripen E has much to recommend it. It has an enviable 10-minute operational turnaround time and is part of a fighter program on time and on budget – a matter of pride to Saab and a rarity in the industry. However, the truly impressive features of the Gripen E are hidden deep within the plane’s design.

A step ahead

Split avionics and a modular system ensure that Gripen E will always be mission-ready. “Computers, processors and electronics are continuously developing and it’s important that you can upgrade these as new tech emerges on the market,” says Saab’s Wing Commander Flying and Gripen test pilot Hans Einerth. The Gripen E system was specifically developed with future progress in mind. By managing to isolate systems affecting the core flight abilities, the plane’s split avionics system allows for the integration of off-the-shelf products.

“The future pilot will need the ability to continuously upgrade the hardware and software and not get stuck in old functionality; this is of increasing importance,” explains Einerth. Early in the development process both Gripen engineers and strategists knew that an upgradeable system would ensure that the fighter would maintain the necessary technological edge in ever-evolving battle scenarios.

Advanced algorithms

Focusing on the system’s software Einerth is keen to underline the importance of the ability to update Gripen’s algorithms to get full use of the airplanes state of the art sensors and datalinks. “Detection and tracking algorithms in our sensors need to be constantly upgraded, as well as the sensors which are using information from different platforms and different sensors.” The algorithm upgrades aid the Electronic Warfare systems and target tracking (both the Raven ES-05 AESA Radar and the infra-red search and track – IRST). “The radar will still be our main sensor in the future and it’s important to be able to update the radar’s detection and tracking algorithms."

Gripen – Constantly evolving

In an uncertain future one certainty is that the pilots with the most up-to-date intelligent systems will be the ones with the leading edge. Gripen is a smart fighter, built to evolve and has its systems ready to be upgraded for any eventuality.  An evolutionary mindset has been at the core of Gripen.
