What happens when a Gripen pilot reaches high altitude and the cabin pressure drops all of a sudden? It can actually have fatal consequences, and therefore it is very important to have systems in place that detect such scenarios in advance and take measures to protect the pilot.
Recently, as a part of Gripen E testing, a number of tests were conducted to verify these systems. Prototype 39-9 onwards, Gripen E has several new systems installed, including an On-Board Oxygen Generating System (OBOGS) and anti-g system.
Two different pressure chambers were used to conduct these tests; one simulated the cabin in the aircraft and the other simulated a non-pressurized space (device space), where OBOGS was mounted. A test doll with a respiratory simulator was used at first to conduct a few tests. This was followed by a test pilot stepping in to do corresponding tests and evaluate the functioning of these systems.
The tests were further enhanced by usage of explosive decompression, simulating the sudden drop in cabin pressure at high altitudes. Low pressure like this could happen in case of an explosion or loss of the aircraft hood. If this happens, the system will quickly detect it, and also take the necessary steps to protect the pilot.
"The focus was to verify that the system gave the correct pressure to the oxygen mask and G-suit depending on the actual altitude. In addition, it was checked that the oxygen level that the system generates ...
With advancements of technologies in the field of defence taking place at a rapid rate, combat and conflict situations will only get more complicated in future. The missiles are going to be bigger, better. What a fighter needs is survivability that is effective.
Enhanced Survivability Technology (ESTL), with its modular structure, offers efficient self-protection for virtually any type of fixed-wing aircraft on a mission-to-mission basis. Missiles of today maybe smart, but ESTL - together with the MAW (Missile Approach Warning) sensors, and AIM-9 and AIM-120 interface - acts as a powerful shield against them.
The Missile Approach Warning system (MAW) provides rapid, accurate detection and tracking data of approaching missiles.
BOP, the lightweight pyrotechnical dispenser, boasts of a forward firing capability enabling superior protection against latest missiles. BOL, on the other hand, is a lightweight electromechanical dispenser holding efficient chaff or IR payloads. Together with BOP, it gives ESTL an advanced countermeasure dispensing capability.
ESTL provides covert sustainable pre-emptive dispensing, missile warning, forward firing of flares, and cocktail dispensing. All these capabilities have been incorporated into the form-factor of a missile utilizing the well-established AIM-9 Sidewinder and AIM-120 AMRAAM interfaces and characteristics for lean aircraft integration.
ESTL offers state-of-the-art self-protection against 1st, 2nd and 3rd generation IR- seekers. A standard, AIM-9 Sidewinder and AIM-120 AMRAAM, interface makes it possible to share ESTL units among the aircraft of an entire fleet, which mean better internal coordination during missions. Not just that, ESTL can handle up to ...
Collaborations like that of Brazilian company Embraer and Saab mean an effective Gripen F development. The collaboration is an example of how true technology transfer works.
On 26 November, Saab completed the successful first flight of the second Gripen E test aircraft.
The second Gripen E test aircraft, designated 39-9, took off on its maiden flight at 09.50 am on 26 November 2018. The test flight was operated from Saab’s airfield at Linköping, Sweden, with Saab test pilot Robin Nordlander at the controls.
“Some people think being a test pilot is the most exciting job in the world and it should be. Flying Gripen E means breaking no sweat though, even on a maiden flight such as this. The flight was so smooth and 39-9 a real pleasure to pilot. I am looking forward to getting it back in the air again and soon putting the new systems to the test,” says Robin Nordlander, Experimental Test Pilot, Saab.

Last month, Saab successfully completed a test flight by a Gripen E aircraft with the Meteor Beyond Visual Range Air-to-Air Missile (BVRAAM) for the first time.
The flight included two Meteor missiles and the Gripen E aircraft (designated 39-8) was operated from Saab’s airfield at Linköping, Sweden.
“The aircraft continues to perform as smoothly as we have seen throughout the whole flight test phase flying with external stores. I’m really looking forward to the upcoming steps in the flight test programme, taking us closer and closer to completing weapon integration. Meteor makes Gripen E extremely capable in the air dominance role”, says Robin Nordlander, Gripen experimental test pilot, Saab.

“My manager called me into the room, shook my hand and said, ‘Congratulations, you’re going to Sweden,’” says António da Fontoura, a hardware and software engineer at AEL.
“We spent a whole week inside the simulators in order to understand how Gripen’s system works, and we could also feel how these systems - such as the helmet - operate. It has a display that keeps information on the pilot’s visor. If you have a designated target, when looking to the side, the helmet points to its location,” he adds.
Since 2015, several engineers like António have been extensively working to develop various parts of the Gripen fighter along with their Swedish colleagues. More than a 100 Brazilian professionals have been trained so far with a majority of them already working at Gripen Design and Development Network (GDDN).
According to General Márcio Bruno Bonotto, "So far, all our expectations have been met. Everything is going as per schedule. 50% of the technology transfer initiatives have been completed. This demonstrates the confidence that FAB and Saab have in each other."
In 2016, Saab and Embraer inaugurated GDDN in Gavião Peixoto, in the state of São Paulo. GDDN is responsible for providing the development environment and simulators required to undertake the fighter development work.
This year in May, Saab unveiled a 5,000-square-meter facility for its future Gripen fighter jet aerostructures plant: Saab Aeronáutica Montagens (SAM). SAM will be responsible for the development of aerostructures for the ...
When Captain Gustavo de Oliveira Pascotto flew Gripen for the first time in 2015, he was very impressed with the way Gripen managed the pilot work load. "What I liked the most was the highly advanced human-machine interface," he said.
Pascotto was one of the first few Brazilian pilots who left Anápolis for F7 in Såtenäs to learn all about the future fighter of their Air Force and pass on this knowledge to his colleagues and newly qualified Gripen instructors.
Fast forward to today, and more than 140 professionals have been trained in Sweden till date. They have already returned to Brazil, and most of them are working at the Gripen Design and Development Network (GDDN).
Today, there is an excitement amongst everyone at the Brazilian Air Force about the arrival of new fighters with people eagerly waiting for Gripen to become operational in Brazil.
“There is a desire and a thrill that has not been seen for a long time. Today we have a group dedicated to studying this aircraft, which asks us a lot of questions. The pilots know they will have the opportunity to operate a modern machine that will enable them to complete their missions successfully. FAB is restructuring and training the squadron to operate Gripen,” says Lieutenant Colonel Renato Leal Leite.
Those who have flown it never forget it. “Flying Gripen was challenging, rewarding and an operational crowning experience,” says Major Gustavo Pascotto.
Teams are working diligently on ...
With every passing year, the signal environment for Electronic Warfare (EW) systems is becoming more and more complex. There are more signals out there, both military and civilian. Hence it becomes imperative to have a smart EW systems which can quickly differentiate a threat signal from other signals.
All around us, there is an Electromagnetic (EM) spectrum which covers all energy radiated by means of electromagnetic waves including radio communication and radar transmission. According to Inga Bergstrom, Sales Director of Gripen EW, Electronic Warfare is the combat for control of the EM spectrum.
“EW may not be the primary function of a fighter, but it is an enabler to conduct a successful mission,” Inga says.
Some of the tactics used by pilots of fighter aircraft to avoid detection include silent flight by reducing emissions, or by flying at low heights. Even then, detection by enemy devices is a possibility, and in the event that Gripen E’s location has been compromised, EW system provides countermeasure techniques, such as Dispensing – in which decoys are released into the air, creating a false target to fool the enemy.
Elaborating on the features of Gripen’s EW system, Inga says that it is all about listening, detecting, identifying, and if you are detected first, about deterring, defending and defeating.
EW has been an important part of Gripen from the beginning. Today, Saab has a small, compact system that does a number of things while also reducing drag and ...

A group of 16 fighter pilots, 4 flight controllers and other personnel from the Brazilian Air Force (FAB) recently undertook a week-long course with Gripen simulators at the Swedish Air Force Combat Simulation Centre (FLSC) in Stockholm, Sweden.
The objective of this course, which included theoretical studies in Brazil, was to familiarize pilots with controls in the Gripen cockpit and understand the fighter system before it arrives in the country. During the week-long course, participants had the opportunity to train in complex scenarios and learn basic combat techniques, tactical datalinks and situational awareness using Gripen simulators.
Each pilot attending the course had flown at least 500 hours in a fighter aircraft. During the course, they went from theory to practice almost immediately and the degree of difficulty in the scenarios increased rapidly, ending in a very complex Beyond-Visual-Range (BVR) combat scenario.
“The pilots are able to fly Gripen in the simulators after only an hour here at the course. The advantages of Gripen is not only in its radars, sensors, weapons and other capabilities, but also the outstanding Human Machine Interface (HMI) that makes Gripen easy for the pilot to use and maneuver. This is something that we can see in the simulators as well,” says Colonel Ricardo Rezende, Leader of the Fox team responsible for the operational issues regarding implementation and developing operational concepts of Gripen in Brazil.
Four out of the 16 pilots who attended the course will be chosen as Gripen pilots ...
