In this program, Brett Emeny, an experienced formation aerobatics pilot, takes us on a walkaround of ZX-RVM, a two-seat trainer version of the Vampire. Originally built in 1958 for the Swiss Air Force, ZK-RVM is now based at New Plymouth, on the North Island of New Zealand, and is a popular attraction at air shows all over the country.
A cockpit tour follows, and we learn a few interesting facts and figures: top speed is about 450 knots, stalling speed 95 knots, service ceiling 35,000 ft. Even though constructed largely of wood, the cabin is pressurized. Like most de Havilland aircraft, the Vampire has nicely balanced controls and is a delight to fly.
We then fly with Brett on an aerobatic sortie, in formation with another Vampire, flown by Paul “Huggy” Hughan.
Multiple cameras provide breathtaking coverage in the cockpit, air-to-air, and from the ground as the formation performs loops, barrel rolls, and several fast, low passes. Pilot concentration is intense as Brett maintains position, his wingtip only a couple of metres from the other aircraft
Paul then lands, leaving Brett to perform a solo routine. We are in the second seat as Brett, talks us through a number of low-level manouvres including loops, four and eight point rolls, and another spectacular low fast pass before breaking to land.
An extra feature of the program is a detailed look at the Goblin Mk 35, an early production jet engine rated at 3,500lb static thrust, which makes an interesting comparison with the engines of today. Early jet engines were notorious for their high fuel consumption, and the Goblin was no exception. ZK-RVM’s internal tanks have a capacity of 1,500 litres, which at low level limits endurance to only one hour. Above 25,000 feet however, fuel consumption is halved.
Fast and low!
