Interesting Flateric; the configuration on the cup and sticker (high wing, apparently cruciform tail) is not the same as the Northrop design as flown. Is it an early version or did McDonnel Douglas (as shown on the cup) have an unsuccessful competitor to Northrop?

SpaceX set for Indonesian satellite launch and Israeli moon mission

Quote
A SpaceX Falcon 9 rocket will launch from Cape Canaveral Thursday, carrying a payload of three very different spacecraft: an Indonesian telecommunications satellite, an experimental spacecraft for the US military and the first commercial mission to attempt a landing on the Moon. Falcon is due to lift off from Space Launch Complex 40 (SLC-40) during a 32-minute window that opens at 20:45 Eastern Time (01:45 UTC on Friday).

The primary payload for Thursday’s launch is Nusantara Satu, a high-throughput communications satellite that will be operated by Indonesia’s PT Pasifik Satelit Nusantara (PSN), however much attention in the build up to launch has been paid to the Israeli Beresheet spacecraft that is piggy-backing on the Falcon 9 launch.

Beresheet will attempt to become the first Israeli spacecraft, and the first privately-operated mission, to land on the Moon. The third satellite aboard Thursday’s launch is S5, a space situational awareness demonstrator for the US Air Force Research Laboratory which will be deployed by Nusantara Satu at a later date.

Retracting into the conformal is something already demonstrated in India with the Illyushin (CARTS), so I'd be surprised if that is not the plan.


Edit: a quick look also includes HAL work as part of the CARTS project.

Postwar Aircraft Projects / Re: Mirage 4000

I think for a Fr Gov to find that it economically acceptable to get a twin jet fighter, it had to be able to replace and do the work of ALL combat aircrafts then in service in the AF AND Navy, that is MIII/5s, Mirage IVs, Jaguars, Mirage F1s, Etendards/SuperEtendards, Crusaders ,(that’s a lot…). The M4000 was too big and expensive for that, and moreover would have been difficult to adapt it to carrier operation on small Fr carriers.
Dassault managed to sell the Rafale to FrAF/Navy cause it was intended to do all that, AA combat, strike, recon, and even nuc strike both from land and carrier, and replace the old stuff. Rafale was a generation after the 4000, so could do the same and more, while being lighter, so finally acceptable for a fr Gov.
Though still a very expensive toy, and deliveries spread several times.

But the 4000 is a beaut for sure.
In term of capabilities, I would really think of it as a "double M2000" :)
Engine more optimized for Hi supersonic, but twice. Almost same aerodynamics and controls system but a bigger airframe , thus more internal fuel so more range (and that was a problem with the 2000).

Main rotor hub that was standing in the middle of the wreckage appeared to be very much a standard H-60 rotor hub  While there could have been much change to the blades they appear to have been mated to a standard hub.

Hi,

here is a nuclear-powered bomber Project,but I can't ID it,and maybe it was just a Hypothetical
one ?.

I wonder if there's a reason they're carrying Derby and not Astra.

Probably it would be.  This document was agreed in 1977, so a bit too late to apply for Vietnam.  Possibly it was even drafted in response to campaigns like that.

I have not seen any good pictures of the main rotor blades that would indicate active rotor control techniques, such as harmonic pitch control (HHC) or individual blade control (IBC) through small outboard flaps on the main rotor blades. However, piezoelectric material or shape memory alloys could have been used in the MRB to actively reduce noise and vibration as these technologies were developed in the late 1990's. Blue Edge demonstrated both modified tip sweep and IBC technologies to reduce rotor noise. Maybe someone has better pictures of the MRBs to make an assessment. The rotor mast probably had some form of masking as well (like the anti-torque rotor) to reduce gearbox noise, possibly similar to the RAH-66 or S-92.
