Denel Joins Local Drive To Develop Ventilators
Denel is mobilising its resources and expertise towards a priority project for the local design and development of medical ventilators in support of the national response to the Covid-19 pandemic.
Danie du Toit, Group Chief Executive of Denel says engineers from Denel Dynamics and Denel Aeronautics are already working round the clock on Project Sabela – ‘we are heeding the call’ – in partnership with other state-owned entities, research bodies and medical technology companies.
“We are still in the early stages of the project, but we are optimistic that this local initiative will help to alleviate the dire need for medical ventilators that are required in great numbers at both public and private hospitals,” says Du Toit.
The defence and technology company is also considering other initiatives in which it can repurpose its current operations and technology to assist the national efforts. This include the production of sanitisers and the conversion of Casspir mine-protected vehicles into ambulances.
“We are proud to respond immediately and positively to a request from the Department of Public Enterprises to drive the ventilator project. As a state-owned company we are committed to utilising our skills, technology and experience in support of the national objectives to combat the scourge of the Covid-19 pandemic at our doorstep”.
A task team has been formed consisting of experts from Denel, Armscor, Eskom, the CSIR and other entities to investigate designs and produce a prototype of a local medical ventilator.
Denel Dynamics is a global leader in the design and manufacturing of sophisticated missile and precision-guided weapon systems and also pioneered research and design for the production of unmanned aerial vehicle systems. Denel Aeronautics is the original equipment manufacturer of the Rooivalk combat support helicopter and design authority of the Oryx medium transport helicopter.
Du Toit says Denel employs some of South Africa’s top engineers, researchers and scientists who have worked on sophisticated technology projects in the past. This accumulated knowledge and expertise will now be mobilised to work closely with medical scientists to produce life-saving ventilators.
Globally the defence industry has been a catalyst for the development of products that have brought immense benefits to the broader society. Innovations that have been derived from Denel’s defence research are vastly used in areas such as border security, agriculture, mining, construction and civilian aerospace within the country.
“Through Project Sabela we are now focusing all our efforts on the current medical and humanitarian crisis facing South Africa and the world,” says Du Toit. “We are confident that we will soon make huge strides in the development of locally-designed ventilators at a time when global shortages are experienced.”
Denel PMP, Africa’s leading manufacturer of small- and medium-calibre ammunition is looking at options to produce sanitisers for industrial and medical uses once the product certification issues have been clarified. Many of the chemicals used in the manufacturing of explosives can also be utilised to make sanitisers.
The Casspir, is a highly mobile and versatile vehicle used extensively in conflict zones in demining and protection operations. Denel Land Systems are looking at options to convert Casspirs into field ambulances, says Du Toit
First Rooivalk Flight 11th February 1990-30 Years On!
The Denel Rooivalk is an attack helicopter manufactured by Denel Aviation of South Africa. Rooivalk is Afrikaans for “Red Falcon”
The Rooivalk attack helicopter First Flight Rooivalk XDM was 30 years ago on the 11th February 1990,back in the days of the then Atlas Aircraft Coporation now known today as Denel Aeronautics.
Development of the type began in 1984 by Atlas Aircraft Coporation its development is closely connected to the Denel Oryx medium transport helicopter, both aircraft being based on the Aerospatiale SA330 Puma Helicopter and having started development at the same time on both projects.
Development of the Rooivalk was protracted due to the impact of limited budgets during the 1990s, and a desire to produce a highly advanced attack helicopter.
Developing an entirely new helicopter from scratch would have involved designing and developing many accompanying subsystems and components, such as the turboshaft engines and the dynamic systems, such as the main and tail rotor systems and the gearboxes.
Due to the great difficulty posed by the prospects of designing and manufacturing a clean-design helicopter, which would have substantially increased the cost and timescale of the project, it was decided to base the attack helicopter upon an existing design. At the time, the SAAF operated two principal helicopter types – the Alouette III and the SA330 Puma.
The Alouette III was a small helicopter which originated from the 1960s; due to the age of the design and a lack of engine power, it was not considered a favourable candidate for further development work.
The Puma was substantially larger and was equipped with more powerful engines; both factors provided a broader basis for the accommodation of additional equipment and for potential growth.
Another key factor for its selection was the parallel development of a localised and improvement model of the Puma in South Africa, known as the Atlas AS32 Oryx. The Oryx possessed an increased power-to-weight ratio and had improved performance in the high temperature climate that the type was typically being operated in; development of the Oryx was far quicker than what would become the Rooivalk as it was a more straightforward program.
Other potential sources were mooted, such as the use of propulsion elements of the Aerospatiale Daulphin ; the adoption of these components has been speculated to have likely resulted in a smaller and potentially more economic rotorcraft.
Ultimately, it was decided to adopt both the powerplant and dynamic systems of the Oryx—which bore significant similarities to their Puma and now Airbus Helicopters AS332 Super Puma ancestors—as the basis for the planned attack helicopter;
Commonality with the Oryx systems would simplify logistics and reduce maintenance costs. This meant that the attack helicopter would have a significantly large airframe, giving it long range and the capability to carry many sensors and armaments.
During the 1980s, the defence budgets of South Africa were relatively generous, especially in contrast to later decades, thus Denel sought to provide a rotorcraft that would be amongst, even potentially superior to, the best attack helicopters in the world.
The helicopter, later named the Rooivalk, was envisioned as an agile, highly sophisticated gunship, especially suited to the threats of the Angolan conflict and countering vehicles such as the T-55 battle tank.
Three Rooivalk attack helicopters have been deployed with the United Nations to support of the stabilization in the Democratic Republic of Congo in 2013.
There has been more occasions where the Rooivalks have seen action with the support of fire power in the DRC on a number of peace support missions since 2013.
The Rooivalk attack helicopter is based at Airforce Base Bloemspruit in the Central Free state province, flying for 16 Squadron, also home to 87 Helicopter Flying School, flying Agusta A109LUH and Oryx helicopters. The South African Airforce have just under a dozen on strength flying to date.
General Fabian “Zakes” Msimang stated:”The continued operation and future sustainability of the hardest working air assets of the SAAF being the Oryx, Rooivalk and C130, rely on an efficient and effective Original Equipment Manufacturer and Technical Design Authority of the Rotary Wing assets” during the recent Prestige day parade held at AFB Swartkop on January 31.
SAAF Museum Flying Day 1 February 2020
The First flight training day for the year 2020 at Airforce Base Swartkop was different this year, it was the South African Airforce’s birthday, which was founded on the 1 February 1920.
With the Prestige Day parade held the day before at Airforce Base Swartkop, many of the aircraft that took part in the mass flypast were present and gave the visiting public a glance at both static and departing aircraft returing to their home bases across South Africa.
The Usual museum aircraft such as the many Museum Harvards, Patchen Explorer, Cessna C185, Kudu and Alouette II, III as well as the Puma continued with currency flights in between display slots.
Friends of the SAAF Museum sold Boere Wors Rolls, Refreshments and held guided tours of the airforce heritage displays located on the base premises.The windsock Café was also open for cool and hot refrements throughout the day.
The days proceedings started with a short display by a 35 Squadron C47TP Martime Dakota from AFB Ysterplaat in Cape Town. Major Paul “Raccoon” Kempthorn flew one of the best Rooivalk displays that we have witnessed in a long time.
The Silver Falcons Aerobatic Team 84 led by new team lead Major Sivu Tangana showed off the tight formation aerobatics of four Pilatus PC7MKIIs.
Two Cessna C208A Caravans from 41 Squadron, who operates out of neighbouring Airforce Base Waterkloof, gave a short formation display. Major Rehan “Kaine” Venter flew his second airshow display as he is now the new Hawk display pilot for 85 Combat Flying School.
Major Geoffrey “Spartan” Cooper flew a great display in the JAS39C Gripen before heading back to Airforce Base Makhado in the Limpopo Province.
The Museum Helicopter assets including the Alouettes II and IIIs closed the flying day with their helicopter display, with a big chance of seeing them do it again on 9th May 2020 at The SAAF Museum Airshow.
Well done to the Museum staff and AFB Swartkop on providing a different flying day as a gift to the public on the South African Airforce Birthday!

SAAF Prestige Evening Awards
The South African Airforce held a Prestige evening awards ceremony at Airforce Base Swartkop on the 31 January 2019.The following day the Airforce was to celebrate 99 years of air power excellence.
The aim of the Prestige Evening is to showcase the service excellence by bestowing honours and eminence to the sterling work the done by the different SAAF entities and individuals in their varied stations.
Invited guests were treated to a mini flying display by various aircraft in the South African Airforce inventory, that being the Silver Falcons led by Major Omphile Matloane ,an Oryx helicopter and the SAAF Museums De Haviland Vampire flown by Lt Col Glen ‘Gringo’ Warden.
Unfortunately there was no Rooivalk display due to the helicopter picking up a snag during its validation flight earlier in the afternoon. The Weather gods also didn’t agree with the evenings proceeding’s and rather made everyone move into Hanger 5 where supper and speeches took place due to the heavy rain downpour.
Once everyone had run for shelter due to the rain in hangar five “The Centre of Aviation Awareness Hanger ” where the to the choir entertained us until the awards ceremony began.
The Chief of the South African Airforce and MCs for the evening congratulated each of the following units for the outstanding contribution to making the organisation a successful team in their different roles they’re play in the SAAF.
For the rest of the evening we got to listen to the South African Airforce Band, with a special musician who joined us for the evening, Mr
Jonas Gwangwa. He has been an important figure in South African jazz for over 40 years.
We would like to say thank you to the South African Airforce for their hospitality and to the Chief of the SAAF for welcoming us to the event personally.We wish the SAAF a great and safe year ahead. The evening ended with a spectacular fireworks display.
