Your Sunday Morning Jet Noise

The HondaJet, which was just granted a type certificate.

  1. Is there any aerodynamic advantage to the over-the-wing mounted engine pods, as opposed to the fuselage mounts most business jets use, other than noise reduction?

  2. Besides the noise reduction, having the weight of the engine on the wings is a little easier on the structure. Might not be as important with a smallish airplane. And in an engine-out situation, there's going to be more adverse yaw.

  3. I know Honda mentioned FOD prevention too. Reminds me of the old English Electric Lightning with the over the wing hardpoints for drop tanks or weapons. The little suckers seem to fly nice enough, but are typical VLJ slow. They were practicing over at KGGG awhile ago.

  4. So how long do you think before Honda car and motorcycle ads mention the Honda Jet?

    I think one of the reasons for the unique engine placement is that placing an engine crossbeam through the composite fuselage would have been much heavier and reduced the baggage compartment. The engine crossbeams on biz jets such as the Cessa Citation and Canadair Challenger are behind the rear pressure bulkhead. They have to be because fuel lines are not allowed in the pressure vessel on anything certified after 1972(?) or thereabouts without heavy and maintenance intensive air tight shrouds around them.
