The Martin Jetpack is a single-person aircraft
under development after 30 years of work. Despite its name, it does not use a jet pack
as such, but ducted fans for lift. Martin Aircraft Company of New Zealand (not
related to Glenn L. Martin Company, the US company also known as Martin Aircraft) developed
it, and they unveiled it on 29 July 2008, at the Experimental Aircraft Association’s
2008 AirVenture in Oshkosh, Wisconsin, US. The US Federal Aviation Administration classified
it as an experimental ultralight airplane. It uses a gasoline (petrol) engine with two
ducted fans to provide lift. It is specified to have a maximum speed of
40 km/h, a flight ceiling of 2,500 ft, a range of 15–20 km and endurance of about 28 minutes
flight. Empty weight is 200 kg. The first customers are said to be first responders.==History==
The Martin Jetpack has been under development for over 30 years. Glenn Neal Martin (not to be confused with
Glenn L. Martin, of US Martin Aircraft) started work on it in his Christchurch garage in the
1980s.New Zealand aviation regulatory authorities approved the Martin Jetpack for a limited
set of manned flight tests in 2013. As of 2016, the price of the commercial production
units is expected to be US$250,000 and sell in the US for US$250,000-350,000
subject to local tax and customization requirements.Glenn Martin suddenly resigned on 4 June 2015 after
investing 30 years in the product.In August 2016, CEO Pete Coker was replaced by the former
CFO James West. The company closed it’s doors in 2019, with
KuangChi Science, Martin Aircraft’s 52% majority shareholder, now looking for a buyer for the
few remaining assets.==Description==
The Martin Jetpack is a small VTOL device with two ducted fans that provide lift and
a 2.0-litre V4 piston 200-horsepower gasoline engine. Although its pilot straps onto it and does
not sit, the device cannot be classed as a backpack device because it is too large to
be worn while walking. However, the Martin Jetpack does not meet
the Federal Aviation Administration’s classification of an ultralight aircraft: it meets weight
and fuel restrictions, but it cannot meet the power-off stall speed requirement. The intention is to create a specific classification
for the jetpack – it uses the same petrol used in cars, is relatively easy to fly, and
is cheaper to maintain and operate than other ultralight aircraft. Most helicopters require a tail rotor to counteract
the rotor torque, which, along with the articulated head complicate flying, construction, and
maintenance enormously. The Martin Jetpack is designed to be torque
neutral – it has no tail rotor, no collective, no articulating or foot pedals – and this
design simplifies flying dramatically. Pitch, roll and yaw are controlled by one
hand, height by the other.===Version P12===
A further version of the Martin Jetpack has been built to prepare for manned flight testing. The new prototype, with the descriptor P12,
has several design improvements over earlier versions, including lowering the position
of the Martin Jetpack’s ducts, which has reportedly resulted in much better maneuverability. It also has a fully integrated fly by wire
system. P12 will be developed into a First Responder
production model. A lighter personal jetpack should be available
in 2017.===Safety features===
In order to enhance safety, the finished product will feature a low opening ballistic parachute
along with carbon fibre landing gear and pilot module.==Flight testing==
On 29 May 2011, the Martin Jetpack successfully completed a remotely controlled unmanned test
flight to 1,500 m (5,000 ft) above sea level, and carried out a successful test of its ballistic
parachute.A second version, designated prototype P12, of the Martin Jetpack received approval
from the New Zealand Civil Aviation Authority (CAA) to begin manned flight testing in August
2013. According to an investor update from August
2016, additional funding will be required to complete the certification process.==Potential markets==
In 2015, the company as part of its listing on the Australian Securities Exchange (ASX:MJP)
stated that the jetpack could be available on the market as in late 2016; it was expected
to sell for approximately US$250,000. However, the delivery date has again been
postponed. Governments are expected to be a large share
of initial consumers. The first production model aimed at military
and first responder emergency crews, such as police, firefighters, and medical personnel,
enabling them to have faster response times, to reach areas inaccessible by road, and to
get to the top of tall buildings quickly. Interested buyers include the government of
the United Arab Emirates; it was reported in November 2015 that Dubai (part of the UAE)
had placed an initial order for twenty units, simulators, and training, for delivery in
2016.==Specifications==
